Perfect sawing in the circus tent
Per Simon Edström with his sawmill.
|Per Simon Edström has the perfect saw house for his Logosol Sawmill: an old circus tent, which also has room for the sawn lumber.
It is never too late to realize your dreams. Ask Per Simon Edström, 78 years old and busy creating the perfect acoustics with the help of 200 spruces and one Logosol Sawmill.
Per Simon Edström has devoted his life to realizing his theatre dreams. He has done the most: Written plays and books, directed, acted, worked with lighting and as a theatre architect. He is mostly known for being the driving force behind the theatre boat Arena, a government-funded region theatre, which berthed at 60 places in the Stockholm and Lake Mälaren archipelagos. This adventure ended in 1985.
”The politicians thought we were too left-winged, so they closed us down,” Per Simon says.
Cognac in the sauna
But instead of retiring, he took the opportunity to realize his own ideas, everything from an experimental theatre at home on his farm, to a wood-heated sauna built of a gigantic cognac barrel.
”The first time we used the sauna there was a delightful scent in it. Later on, the scent disappeared and you needed a bottle of cognac each time to recreate the atmosphere. It became too expensive to use the sauna, Per Simon says jokingly.
His great passion is the theatre on his farm. He compares it to an instrument, which you have to give the correct acoustics, and there also has to be a closeness between the audience and the actors. In order to exploring the possibilities, he built his own theatre called Modellen (the model) with room for an audience of 80 people.
Here he has produced plays in all kinds of theatre forms, and the experiments have proven what Per always has maintained.
”The classical arena theatre is superior,” he says.
The arena is like a circus with the audience around the entire ring. A circus tent lacks the acoustics, and the arenas of today, like the Globe Arena in Stockholm, lack the closeness to the audience. The best would be an arena of wood, like the Drottningholm Theatre.
“The walls will speak if they are built of two inch thick spruce boards,” Per Simon says.
He designed an arena theatre for Ramallah, the Palestinians’ temporary capital on the West Bank. It was never built, but everything needed for realizing the dream was closer at hand, at home on Värmdö.
“50 years ago, my father planted spruces in an enclosed pastureland. To be honest, I did not like that the pastureland disappeared,” says Per Simon, who after a couple of years changed his opinion.
”Instead of thinning, we sold Christmas trees. People came here by car with newly-bought roof racks and axes. They cut down their Christmas trees themselves and paid 25 Swedish kronor each.” As time went by, the spruces grew tall. Per Simon saw the opportunity to restore the old pastureland and get himself building material for the perfect arena theatre. He bought an extended and completely equipped Logosol Sawmill, which was placed in a circus tent.
”You can’t find a better sawing house. The sawmill and the lumber are protected from wind and weather.”
The theatre manager had no difficulty in learning how to handle the sawmill. When he was young, he worked as a timber estimator in the forest, and he trained two persons who used the first chainsaws. Nowadays, he also has help when sawing, but he himself takes care of the most important job: sharpening the chains.
“A sharp chain means everything, especially when you are cutting into a spruce with hard knots in it,” Per Simon states.
Officially a barn
Actually, it is not a theatre he is building. The 24 metre (79 ft) long building will primarily be a hay barn for the ewes and lambs on the farm. Today the bales of hay are stored in two old circus wagons.
”But when the barn is empty in the summer, there is nothing stopping you from having a theatre here, so you might as well build it right in the first place,” Per Simon says.
The ’theatre barn’ will also serve as an exhibition room for a travelling waxworks show from the 19th century. It has been exhibited in the Museum of National Antiquities, but today it is stored up. *
High potential for small-scale wood processing!
|This tree (Bulnesia sarmientoi) is very unique for its dark green color and its special oil content which makes it very resistant against decompostation. It weighs between 1100 to 1200 kg / m3 (15% humidity) and is also used for posts. Dieter Stosiek (closest) helps lifting the tree.
|Although we are absolute beginners, we were able to cut some really fine boards.|
|Here Dieter Stosiek is cutting an Aspidosperma quebracho-blanco. These trees are most interesting for us as they normally form very good and straight trunks and are not as hard as the others. They weigh around 880 to 900 kg / m3 (15 % humidity). These trees were used in former times by the Mennonites for building the roof-truss of their houses, but was later on replaced by imported beams from the eastern part of Paraguay. It needs a special treatment and careful drying process in order to avoid deformation. It will be very interesting for building gates, sheds, houses for the workers and in the corral.
After work was done, the cut material and the sawmill are transported to a shed at the center of the farm.

Logosol got a letter from Dieter Stosiek. For the last 15 years he´s been living in the Central Chaco of Paraguay. He bought a Logosol M7 and are now planning for demonstrations and sales.
Read his letter to Logosol:
"For the last 15 years I am living in the Central Chaco of Paraguay. I have a Master of Science degree in tropical agriculture from Hohenheim University in Germany and came to Paraguay as a member of the GTZ (Gesellschaft für Technische Zusammenarbeit) to work in a bilateral development project at an agricultural experimental station. In 1995 I started my own consulting, specializing in land development and farm planning. For the last 10 years I worked as an expert for the National Forestry Service and the Ministry of Environment, advising the local farmers in setting up their cattle ranches.
In the Paraguayan Chaco between 20.000 to 50.000 ha of natural woodland will be cleared annually and transformed into pastures. So far, only a small amount of the resulting timber is used - mainly as posts for fences and corrals. All the other wood products (boards, beams...) for necessary farm constructions (gates, sheds, corral, houses) comes mainly from the eastern regions of Paraguay where we have much higher annual rainfalls and a much better infrastructure.
So far, the transport of trunks to the populated centers in the Chaco (German speaking Mennonite colonies) for further processing, is due to the long distances, poor infrastructure and often low trunk quality not profitable.
A rising demand of construction wood and decreasing natural resources in the eastern region, led to steadily increasing timber prices and at the same time to a decreasing quality. In the last years I spoke with many farmers about the problem and most of them would be very interested in a flexible, comparatively cheap wood processing system, to make use of their own resources.
This is not only an economic but also an ecological concern. Normally, almost all the residues of the woodland clearing will be burned about one to two years after the deforestation. The possibility of processing their own trunks directly on the farm with a chainsaw operated sawmill, can greatly reduce this waste of valuable timber.
For these reasons, I bought on my last trip to Germany in August a LOGOSOL M7 from your representative in Bad Saulgau and shipped it to Paraguay where it arrived around Christmas.
The unit will be operated with a Stihl MS660 chain saw, mainly for testing and demonstration. We have tested the sawmill with different types of wood and I was really pleased of the good results we could achieve right from the start.
As soon as we our selves have enough operating experience, we will invite - for a start - all the local farmers for an on farm demonstration. I’m very confident, that there will be a high potential for selling your products on the local market. Basically we have three target groups: German speaking Mennonites, Paraguayan and Brazilian ranchers and investors from Europe. The farms range between some hundred to some ten thousand hectares with demand for low cost solutions like your Timmerjigg or Big Mill System to more expensive and more sophisticated units like the M7 or the new band saw LM40 you developed.
A Format Saw with high quality and stability
The Logosol PS315!
Logosol PS315 is a precision saw within reach for small joinery shops and choosy amateurs. It is just as stable and versatile as many industrial saws.
We have many names for the things we love, and this type of machine is called a dimensioning saw, trimming saw or resaw. They come in different sizes, from simple constructions of sheet metal, to the industrial, computer-controlled, cast iron machines.
Together with the jointer/planer and the upright drilling machine, it is one of the most important machines in a joinery shop.
Logosol has chosen to call it PS315. The abbreviation stands for ‘precision saw’ and the figures stand for the dimension of the tiltable saw blade. It looks like a professional saw, it works like a professional saw, and it feels like a professional saw. But the price tag shows a reasonable price. Logosol PS315 has a combined machine table and frame in cast iron. The carriage runs on sixteen steel balls with a diameter of 19 mm (0.7”). The balls run in tempered steel tracks, which are fitted in the cast iron. It is a rigid construction to ensure the highest precision. All fences are of indus-trial quality and can be precision-adjusted.
The adjustable circular saw blade is 315 mm (12”) in diameter, and is suitable for both laminates and solid wood. The carriage takes pieces that are up to 1200 mm (47”) wide. If you fit an extension table it will take all sizes. This precision saw is a versatile machine. You can use it for cross cutting, mitring and rip sawing. It can also be used for grooving and tenoning, or for dimensioning board material. It is a machine that the pros cannot do without. With Logosol PS315, you too can allow yourself that luxury.
Logosol Goes “Hollywood”
“They’re gonna put me in the movies…and all I gotta do is act naturally!” Remember that song by Buck Owens? That’s the tune the WoodWorkers Mill is singing these days.
|The WoodWorkers Mill - a star in the video Logs to Lumber. “The mill did great!” George Vondriska, woodworking expert, says.|
The Logosol WoodWorkers Mill was recently used in a WWGOA (WoodWorkers Guild of America) video titled “Logs to Lumber.” The video, hosted by nationally recognized woodworking expert, George Vondriska, covers how logs are converted to usable lumber, plain sawn versus quarter sawn, and air drying versus kiln drying, including a visit to a solar kiln. It also touches on hardwood grading and, once dry, how rough sawn lumber becomes suitable for high quality cabinet and furniture work. It promises to be a valuable video on the basics, as well as advanced techniques of bringing the best lumber out of a log.
Vondriska is the Managing Editor of the WWGOA web site where users have free access to a variety of woodworking articles covering tool reviews, shop improvements, and assorted tips and techniques. He also owns and operates The Wild Earth Woodworking School in Hudson, WI where he teaches hands-on woodworking classes. George, who is a former contributing editor and writer for American Woodworker Magazine, remembers the WoodWorkers Mill from when it was recognized as one of the top New Tools of the Year by that magazine.
The WoodWorkers Mill was chosen by WWGOA for this video because of its position in the marketplace. When Vondriska had to choose a sawmill for the upcoming DVD, the WoodWorkers Mill’s price point, intuitive use, and versatility made it the clear choice. “I’d had some previous experience with small scale sawmills prior to this,” Vondriska said. “I knew, from talking to many woodworking students over the years, that the Woodworker’s Mill would be a great fit for the video.”
The video, which was shot over a two day period, will edit down into two hours when complete. In addition to lending his own expertise, Vondriska used industry experts to help explain how to optimize what a log can produce, and how the solar kiln works. The DVD will be released in Spring 2009 exclusively through the WoodWorkers Guild of America (WWGOA).
So, how did the WoodWorkers Mill perform? “The mill did great!” George says. “It performed right on cue – never missed a line. However there was some confusion whenever the director yelled ‘cut!’”
Now that the shooting is complete the Woodworker’s Mill will remain at The Wild Earth Woodworking School where it will be integrated into the curriculum. Vondriska does frequent presentations for clubs, guilds, schools, and woodworking shows and the mill has already traveled to some of those events.
Sheriff’s Office with a solid desk of oak
Leake county, Mississippi sheriff Greg Waggoner has what may be one of the most elegant offices of any sheriff in the country. The desk, cabinets, shelving and trim were all cut on the PH260 planer/molder and installed by volunteer inmates at the regional prison next to his office.
This book case and media center show off the quality of the trim and the attention to detail that Steve and his crew put into the office.
The woodwork at the Leake county sheriff’s office is as functional as it is elegant.
Steve Whittle supervised the inmates who volunteered to cut and install the trim in the sheriff’s office. According to Steve, the PH260 was easy to learn to use, and was a central part of teaching the inmates skills that they could use when they left prison.
Walking into the office, Olof Almstrom, Charlie Griffin, and I were struck by the elegance of the wide crown molding, wood paneling, and beautifully built book cases. A hand crafted solid oak desk dominated one side of the room. With a cowskin rug on the floor and Remington prints on the wall, the office was one that any Texas lawyer would be proud to work in.
But this is the office of Leake county, Mississippi sheriff Greg Waggoner. And in spite of its elegant appearance, the office was built and furnished on a very limited budget.
By David Boyt
Sheriff Waggoner has the sort of no-nonsense personality that commands respect from first eye contact. He extended to us the gracious hospitality for which the south is well known, kindly taking time from his morning schedule (which included a meeting with the Governor) to visit with us about the role the Logosol PH260 played in furnishing his office, as well as the rest of the building.
Built with volunteer prison labor
When the new sheriff’s office was proposed two years ago, there were the usual questions of how to keep expenses to a minimum. The one thing not in short supply was labor. Other than the concrete, brick work, and sheet rock finishing, the entire office building-including the electrical, plumbing and heating & air conditioning-was built with volunteer prison labor. The inmates are generally glad to get out for a while, says Sheriff Waggoner. "The only problem was finding the ones who wanted to work."
"We wanted the office to look nice, but we knew we couldn’t go out and buy all of the materials. For example, the cost of the trim and cabinets would have been about $37,000. So we decided to buy a four-head planer molder." Steve Whittle, who supervised the project, recalls "We had the inmate labor and access to oak, so we decided we could save a lot of money if we bought a planer/ molder. I got on the internet and searched for machines. I found a company called Logosol located in Madison [Mississippi], so I went up to look at it. They gave a demonstration, and we bought one."
Over the next eight months, Steve and his group of volunteers produced and installed trim and moldings for the office. Not satisfied to stop with that, they built the cabinets, book shelves, tables, shelving to hold evidence, and even a built-in wash basin for the Sheriff’s office.
Covered the old desk with oak
The desk in the office was absolutely beautiful. "They took an old surplus desk, and covered it with oak," the Sheriff explained. "This [workmanship quality] was a lot more than what I expected. You could call Steve a perfectionist. The crown molding in my office looked fine to me, but the next morning, Steve had taken it all down and was having the inmates re-install it." "It wasn’t sitting against the sheet rock just right," recalled Steve.
This attention to detail paid off in more ways than one. "We had a lot of good inmate labor." says Steve. "By the time we were finished, they had a lot of pride in their work."
He continued, "A lot of these are good guys that just didn’t get raised to stay out of trouble. They get out here and get some good supervision. I’ve gotten calls from several after they got out to tell me that they’ve gotten jobs installing trim."
It is obvious that Steve takes pride in more than just the woodwork. With the job finished, the machine is idle, for now. Soon, they hope to use some of the inmates to teach others how to run it, and continue to use it to teach a useful trade.
The Children Learn Everything from Woodworking
The children are gathered for a woodworking lesson. But it is also a lesson in mathematics, language and geography.
Wood types from all over the world are represented in the stock, which makes the woodworking a geography lesson.
Woodworking is a subject that usually gets stuck in the middle when there is reorganization and downsizing of a school. But the woodworking still exists, due to enthusiastic teachers who know that this subject is important. One of them is Stig Fritzon, teacher in wood- and metalworking in Sweden.
This article came about, due to the fact that Stig ordered a jointer/planer from Logosol this spring. He was so pleased with it that he contacted Logosol to praise the machine. “This is a small professional machine,” says Stig, who especially likes that you can joint and plane without having to fold up the planer table or move the chip duct between the two operations.
We visited the school to tell them how good the machine is. Now that we have done that, the article will continue to be about the school subject woodworking and the enthusiasts who have seen to it that the subject is still on the schedule, even though the theoretical subjects are the most emphasized when the choice of which to offer is discussed by school administrators. “Here, the children have the opportunity to try theoretical knowledge in practice,” says Stig just before welcoming a group of third graders to the lesson.
Everybody can work with wood
In class there are also two special school pupils. It is impossible to tell the difference between work done by the ordinary pupils and the special school pupils. Woodworking is a subject that levels out differences.
”All pupils can do this, and all pupils are good enough. I have never met anyone who is all thumbs. We all need different amounts of time, but the things we make in the woodworking class are not judged by how quickly they are produced but by the result,” says Stig.
Woodworking gives both self-confidence and another way to knowledge than the books offer. “All subjects are included in woodworking,” says Stig and explains what woodworking provides: ”Touching is knowing.”
He shows how geography is lying on the shelves in the form of wood pieces from all over the world. Here, both America and Spain are represented in the form of oak and olive wood.
Easier to learn
You have to know mathematics to be able to calculate how to make these things. Furthermore, you have to calculate three dimensions, which makes the whole thing extra tricky.
”Did you see how easily he worked out where the center is? This boy has a problem with figures,” says Stig when seeing how one of the special school pupils without hesitation uses the folding rule for measuring where he is to place the hook for hanging up a small shelf.
Another important aspect of woodworking is that it helps the pupils to build up their self-confidence. Stig encour-ages his pupils by exhibiting their work in a showcase for one week. In addition, he takes photos of the work and publishes them on the Internet.
In the woodwork classroom, they use real tools and real machines. This is a place of work and not a place where you can run about and play.
“You should have respect for the machines and the tools, but not be afraid of them,” says Stig.
The lesson with the third grade in the Kesberg School in Vårgårda is very soon over. When Stig tells the pupils that it is time for tidying up, they are all protesting. Woodworking is not only educative, it is also great fun.
“There’s money to be made with this machine”
I met brothers John and Ron Arnett at the Logosol open house in Jackson, Mississippi last summer. They had just finished a job resurfacing the bleachers in a local high school gymnasium and were looking for ideas on other ways to use the PH260 in their business. So how were they doing? I drove up to their business near the tiny northwest Missouri town of Philadelphia to find out. Coming in from the blowing snow, the first order of business was to “inspect” their old pot-bellied wood stove.

|John Arnett (right) puts a board through the PH260 to test the knife settings. His brother Ron (center) and nephew Zach watch the outfeed.
Ron Arnett shows the final trim test piece. They are now ready to start production.
The shop is a 40’ by 60’ sheet metal building housing a variety of production equipment, including table saws, radial arm saws, a band resaw and, of course their PH260 moulder/planer. The Arnett brothers have put a lot of thought into the flow of materials when they arranged their machines. Although the shop is small, it is not cluttered, and material flows easily from one machine to the next one. All guards and shields in place, and the Arnetts have added to them to make it almost impossible to get a finger near the blade. “When we start our next production run, we plan to have some of our kids working with us.” explained Ron. “It gives them a little spending money, and it keeps them out of trouble.” While my hands thawed out over the wood stove, Ron talked about his experiences with the PH260.
“There’s money to be made with this machine,” he says. “We bought it about this time last year [Feb 2007]. My brother John found it on the internet, and we got a job refinishing bleachers in a gymnasium. What he bid on the school job was double the price of the Logosol, so we knew we could buy it and pay for it and put the other half in our pocket. We took the old boards off, ran them through the Logosol to clean them up, applied a new polyurethane finish, and put them right back in place. John and I had our kids, plus three nieces and nephews up there helping. We brought the Logosol to the school and set it up right in the gymnasium with a rotary three-phase converter and dust collector.” After that, they started to look for other ways to use the machine.
Things had changed quite a bit for the Arnett brothers since we met at the Open House. They visited several local lumber yards, one of which produced its own moulding on a high production six-head machine.
The owner showed Ron a sample of his moulding and asked what he thought of it. “It had ripples in it and some tear-out. I think he may have pushed it through the machine too fast,”, said Ron. “John told him that in our shop, trim that looked like that went into the wood stove. John is a little too direct, sometimes!” His direct approach, followed up with some samples of trim from the Logosol convinced the owner of the lumber yard to shut down his production moulder and buy his trim from the Arnett brothers. “This looks like a good, long-term job for us,” says Ron.
Ron and John make trim rings that they can leave with potential customers. This is a set of 8 inch sample trim sections on a short length of chain. Ron writes the knife numbers on the back of each piece for reference. “When a customer wants a certain piece of trim, he can read off the numbers, and I know exactly how to set up the machine,” he said. Matching trim is also a strong selling point. “We just trace around the trim on a piece of trim and fax that to Logosol’s knife maker, and he can grind a set of blades for that profile.” More than a dozen pattern knives hang on the wall behind the machine. “They [the knives] are expensive,” says Ron, ‘but we’ve got more on order.” To sharpen the blades, they send them out to a local sharpening shop.
According to John, it takes about 30 minutes to change the knives. The focus is on producing a high-quality product.
“We generally run this at the slowest feed rate-- I think its about 11 linear feet per minute-- to give the smoothest cut. We don’t push it,” said Ron. “I think the lumber company probably lost quality because they were pushing the trim through their machine to fast. They were set up like a factory,” he concluded.
The positive response to the quality of their products has resulted in a few changes around the shop. A new band resaw sits next to the Logosol. “When we started it up, the lights in the shop just dimmed.” recalls Ron. “We’ve got an electrician coming in tomorrow to put in some heavier wiring for us.” They are also considering installing a chip bailer. “Hopefully when we do that, we’ll be able to sell the shavings for bedding. There’s money to be made here, but you have to look at every possible aspect of it, including the waste,” says Ron. “By this time next year, we’d like to be in a building twice this size.” One thing is certain—the PH260 will be in it! According to Ron, “We hope that the Logosol lasts a long time, but at the same time, we hope to keep it busy enough that we wear it out!”
There’s nothing better than words of wisdom from someone who has been successful. Ron says that the best approach is always to be honest with your customer and produce a good quality product. “The biggest thing is don’t feed the customer a bunch of bull. Just be yourself and show ‘em what you’ve got.” *
Pleased with the stack cutter from Logosol!
Bettna has installed a second planing/moulding line to meet a growing demand for wooden packages, mouldings and panelling.
”Our standard range is also special for this district,” Kåre Björnsbråten says and examines a 120 mm wide skirting board.
Kåre Björnsbråten runs the Bettna Sawmill with seven employees. With every year that passes, he becomes more and more pleased with the stack cutter from Logosol.
“Especially when we were rebuilding the planer shop. At that time, the moveable stack cutter was invaluable,” says Kåre.
He bought the stack cutter to saw board stacks into accurate lengths, both for the manufacturing of wooden packages and for his DIY store. The timber is nowadays bought from larger sawmills.
”At the beginning, I was hesitant about the stack cutter. It seemed weak, but I have changed my opinion on this point,” says Kåre.
Kåre realized how good the stack cutter is when the planer shop was being enlarged. Then there was no room for the stack cutter in the shop. No problem: it has wheels, and due to this it could temporarily be placed outdoors, where it continues to do good service.
“This arrangement doesn’t look all that nice,” Kåre says apologetically and explains that the stack cutter will be placed under roof again as soon as the building project is finished.
He does not have to excuse himself. Logosol has designed the stack cutter to stand up to outdoor use.
Compressed Planer Shavings Save Space and Creates Income
Lennart had no previous experience of planing when he bought his Logosol PH260. Two years later, he is a skilled pro.
– I bought the briquette press to be able to handle all the shavings from the planer in a rational way, Lennart Eriksson says.
When a small planer shop receives a big order it meets with a great problem. What should you do with all the planer shavings?
Lennart Eriksson solved this problem with a briquette press. The compressed shavings became easier to handle and in addition he got a product he could sell.
Lennart Eriksson lives outside Mellerud in Sweden. He is an instrument technician at a paper mill. A couple of years ago, he bought a Logosol PH260. His aim was to develop his own business, and his partner Annette Lundgren shared the same vision.
"Annette is a handcrafter and she was thinking of starting a shop together with a friend," Lennart says.
Big order from DIY store
The couple bought a small farm, just outside the town, for both their businesses. The old barn became Lennart’s Wood & Planer Shop, and in the dwelling house Annette opened the handicraft shop.
Just over a year ago, Lennart received a big order from a small DIY store.
It was an order for so much four-sided planing, that it was equivalent to a half-time job. Lennart resigned from his job at the paper mill, and started to plane. Everything went according to plan, with the exception of all the planer shavings. He could dispose of it as stall bedding to local farmers, but handling it was time-consuming.
Lennart is of the type who sees opportunities where others see problems. He bought a briquette press and installed it above the planer. The shavings are transported direct from the planer to a chip duct on top of the press. The finished briquettes end up in large sacks and are then delivered to be used as solid fuel.
"The volume is reduced and the briquettes are in demand," says Lennart, who himself uses direct-acting electric heating at home. "But I have installed a stove that takes briquettes."
Planing for sawmills
The contract with the DIY store was time limited, and when it expired Lennart chose to return to the paper mill, where he now works in five shifts as an instrument technician. This is an occupational group that installs and maintains measuring and regulating systems, something that suits a clever person like Lennart. In his time off, he works at the planer shop, producing customized mouldings to customers, and planing on subcontract for small, local sawmills.
"In the long run, the goal is that Annette and I can move out to the farm and earn our living from our businesses," says Lennart, who has several other ideas about developing the business.
Modern Vikings’ voyage to Vinland starts here
The future Vikings next to the log, which is to become the ship that will take them over the Atlantic to America, where the Vikings landed 400 years before Columbus.
Meter after meter of first-class oak, without a single knot.
The Swedish navy planted the oaks in the 1800s to have building material for warships.
The Logosol Big Mill LSG can handle long logs of really large diameters.
It is early morning on the island Visingsö in Sweden’s second largest lake, Vättern. With the exception of the persistent whirring from a chainsaw, this could just as well be a scene from a thousand years ago. Here, the keel is being shaped for a 52 feet long Viking ship, a knarr, which will sail all the way to America, or “Vinland”, as the Vikings would have said.
Members of the association Vittfarne are making the keel using a sawmill from Logosol, a Big Mill LSG. The log is as straight as an oak can be. When the slab is lifted away, something is revealed that few are privileged to see: Meter after meter of beautifully patterned oak, completely free from knots.
"Are we really going to build a boat of this?" Rickard Zetterqvist asks when seeing what has been hidden under the bark.
But it is for building a ship. The Swedish State has given the association permission to cut down oaks on Visingö.
"The oak wood was planted in the 1800s to meet the navy’s demand for building material. The trees are intended for building ships," says Håkan Altrock.
The story is probably true
He is the president of the association Vittfarne. It was founded in order to carry out a scientific expedition in 2004. The aim was to look into the veracity of the story about Ingvar Vittfarne’s (Ingvar the Far-Travelled’s) eastbound passage. The voyage is described on some thirty rune stones and in one of the Icelandic sagas.
Ingvar reached as far as Särkland (the land of the Saracens), the Vikings’ name of the Muslim countries. Archaeological finds indicate that he and his crew travelled through Georgia and Azerbaijan, all the way to the Caspian Sea. Ingvar and the majority of his crew died in battle or succumbed to diseases.
Historians have doubted the veracity of the story, since the route means that you have to drag the ship a long way on land, on narrow tracks and over high mountains.
"There is nothing that contradicts that Ingvar really travelled this route," says Håkan, who was the leader of the expedition and took the ship as far as the Caspian Sea.
They build as the Vikings
But there are other Viking Age passages worth examining, especially the theory that the Scandinavians discovered America several hundred years before Columbus, and that Vinland, which is mentioned several times in old stories, was eastern Canada.
The present-day voyage to Vinland on a Viking ship starts with cutting the keel this autumn morning on the island Visingsö.
"We will as far as possible build the ship using methods from the Viking Age," says Håkan.
The Vikings cut the keel and other rougher details using axes, and they cleaved the logs for planking. This meth-od is too time-consuming for the project. For this reason, a chainsaw and the Big Mill LSG are being used instead.
Håkan expects that they can produce sawn timber of the same quality. The timber becomes stronger if you follow the grain, which is one of the reasons that the Viking ships were so sleek and hardy.
According to the preliminary schedule, test sailings will be carried out in seven years. In ten years, the trip will begin starting from Stockholm, then via Norwegian Bergen to Iceland, Greenland, Labrador, Newfoundland and Nova Scotia.
The crew will navigate using Viking Age methods. Present on the voyage will be archaeologists, who will look for settlements along the way on which the Vikings once came.
Logosol cut the first FSC marked log in Sweden
|The log arrives from Brazil.|
The log that was cut with Logosol’s Jungle Mill weighed over 4 tonnes.
|The sawmill is mounted!|
|Bengt-Olov Byström poses next to the log.|
|The first FSC sawn board in Sweden was cut by Logosol!|
Logosol was one of the first Swedish companies to join FSC, an international organisation that work for environmentally friendly forestry. At the Elmia Wood Fair in 1998, Logosol cut the first FSC marked log in Sweden.
“In connection with our commitment to village forestry, we encouraged the eco-labelling of the forests of the world that was introduced at that time. Together with the Worldwide Fund for Nature we wanted to show that it was possible to conduct environmentally friendly forestry also in the rainforest,” says Joakim Byström, one of the owners of Logosol.
Environmentally friendly forestry
After having been in the Solomon Islands, Logosol had developed the Jungle Mill, a sawmill that can handle large-diameter timber.
“This product is a tangible contribution to environmentally friendly forestry in rainforests,” Joakim Byström says.
A large-diameter log was transported from the jungles of Amazonas to Elmia Wood Fair in Jönköping, Sweden. The log of high-grade wood weighed 4.5 tonnes and the diameter was 1.3 metre (4 ft)!
“We had a big audience when we cut up the log using the Jungle Mill. After that, the boards were auctioned, and the money went to the Worldwide Fund for Nature,” Joakim Byström remembers.
A successful cooperation
The wide boards were impressive, and as a memory of the event some boards were used for making a large conference table to Logosol’s Swedish head office in Härnösand. The table is used every day and it is a real work of art!
”The project was a successful cooperation between the Worldwide Fund for Nature, Stihl, Elmia Wood Fair and Logosol,” says Joakim Byström, who still remembers the scent of sawdust from high-grade wood that he felt when he was cutting the first board from the 4-tonne log.
”It was an amazing feeling, moving from abstract discussions about environmental problems to a practical demonstration of a solution to how the rainforest can be used environmentally friendly.
FSC, Forest Stewardship Council, is an international organisation which promotes an environmental, socially responsible and economically viable use of the forests of the world.
Joakim’s work also attracted the attention of His Majesty the King of Sweden. For his achievements in ”combining research, environmental commitment and private enterprice” Joakim Byström was awarded an environmental grant of SEK50 000 from King Carl XIV Gustav ‘s 50th Anniversary Fund.
Logs before and after the Timberjig
The difference between the photos is a Timberjig. Earlier, all trees became firewood, now Goran Sahlqvist cuts lumber and has, among other things, built this fence.
Photo: Birgitta Sahlqvist
‘It’s insane that I didn’t buy this thing earlier.’ It is not only Goran Sahlqvist that is satisfied with the Timberjigg. Also his wife Birgitta and their neighbors are pleased.
Birgitta was so satisfied with her husband’s work that she sent some photos of the result to Fresh Cut with the following message: ‘Look what a beautiful fence and gate we’ve got. All thanks to Logosol. I have also sent you a photo of the firewood that was what we got before my husband found Logosol. He is delighted! And what else can I be but satisfied with these products?’
Needed a new fence
Goran and Birgitta had access to timber from some vacant lots in the neighborhood. Before the Timberjig was purchased, all the timber became firewood. It was the need for a new fence that brought about the purchase. Goran thought that buying lumber when you have access to trees was foolish. He had a chainsaw and the Timberjig is reasonably priced.
‘The old chainsaw was too weak. I bought a bigger Stihl chainsaw, and now I can quickly cut the lumber I need,’ says Goran. The fence became a success, and he has received a lot of admiration from his neighbors.
Better than TV
As a result, Goran got hooked on cutting lumber and has felled a number of trees and cut them for future projects. Even though the sawmill is of the smallest model, he has succeeded in cutting spruces that have been close to three feet in diameter on the root side.
‘I just can’t sit still. Sawing lumber is fun, and at the same time relaxing. In addition, you save a bit of money,’ says Goran, who warmly recommends sawing to everyone that wants to fill his or her life with something more than television.
The Logs Go on Private Railway to the Sawmill
Bo Malmborg works as a production technology manager at Electrolux in Motala, so it is not surprising that the logistics around the sawmill are well thought out. The logs arrive on the track to the right. Then, they are lifted onto the Logosol Sawmill with the help of the electric gantry crane. Finally, the boards and planks are placed on the wagon to the left and transported to be seasoned.
Even small railways require a turntable. Behind you can see the line’s engine depot. The engines and the wagons Bo has built himself.
Bo Malmborg recommends using a gantry crane for lifting logs. He himself has two, and this one is portable.
Bo Malmborg is probably the only Logosol-Sawmill owner in the world who carries logs from the forest to the sawmill on his own personal railway. The line is 2.3 kilometers (1.4 miles) long, and is found in Tiveden in Sweden.
The idea of building a railway started to develop in 1969, when Bo Malmborg’s parents bought a small forest property at lake Örkagen. To provide capital for the purchase they harvested trees on the property, but some logs were left on the other side of a bog.
"I considered making an aerial ropeway, and also other methods to carry home the logs," says Bo.
Most of all, he wanted to build a railway, inspired by the Märklin trains of his childhood. But how would he, as a private person, be able to build a full-scale railway? During his military service, five years later, he found the solution by a roadside outside the town Tibro.
Railway from a peat bog
"There was a pile of rails from a closed-down peat litter factory. I bought the rails and financed the purchase and the transport by selling half of the rails to a scrap dealer. I kept all the switches and axles."
The width of the track is 600 mm (24"), the standard for small industrial railways. In Sweden, this type of railway has mostly been used on peat bogs. The trains have been replaced by vehicles with balloon tires, which has resulted in a supply of rails, axles, wagons and engines available at reasonable prices. The laying of the rails started immediately, but when the goal was reached, all the remaining logs had been used up for making the ties of the railway.
Since then, the railway has been improved and extended success-ively, and today it is 2.3 kilometers (1.4 miles) long.
The first board hangs on the wall
With their own forest, railway and a constant need for timber for hobbies and renovations of the buildings on the property, it was only a matter of time before a sawmill was acquired. Today, the Logosol Sawmill has its natural place by the railway.
"The first sawn board hangs on the wall in the bedroom," says Bo’s wife Elisabeth, who has become accustomed to the many years of railway building.
"At my first visit to my then future parents-in-law, we spent two days painting railway wagons."
The combination "railway and Logosol Sawmill" is both entertaining and useful. In civilian life, Bo is a production technology manager at Electrolux’s stove factory in Motala, and at work he organizes streamlined productions. In the case of the railway, he has also succeeded in this.
Safe lifting in the forest
Örkaggen Railway, as the line is called, has several technical solutions that other Logosol Sawmill owners should consider copying. Especially when it comes to log handling.
"In the forest we pull the logs to the tracks with the help of an iron horse, and load them on the wagon using a gantry crane," says Bo.
The gantry crane is easy to take down and bring with you out into the forest. It straddles the wagon, and the logs are lifted by an ordinary chain hoist which can be pushed backwards and forwards on the crane beam. This results in safe lifting, even when handling heavy logs.
The Logosol Sawmill stands beside a double track under a big gantry crane, which extends over the two tracks and the sawmill. The wagons loaded with logs stands on the track furthest away from the sawmill. With the help of the gantry crane the logs are lifted over to the sawmill. The processed timber is then placed on another railway wagon on the track closest to the Logosol Sawmill.
Even more enjoyable
The most dangerous operation, when it comes to all types of sawmills, is handling of heavy logs. Many people have a hoist fastened to the ceiling above the Logosol Sawmill, but what do you do when there is no ceiling? Well, you build yourself a gantry crane. The example from Örkaggen Railway shows that it can be used both in the forest and by the sawmill.
"Building a gantry crane is not so complicated. I welded together rails in triangles to be used as legs, and used a part from an industrial conveyor belt as crane beam enabling the hoist to be moved. But you can just as well use an I-beam," Bo states.
It can also be worth laying rails next to the Logosol Sawmill and obtain a couple of wheel axles, to build a movable log table. Carrying logs on rails only takes a fractional part of the effort, compared to using rubber wheels on the ground. Furthermore, there is no denying that wagons and a gantry crane make the sawing even more enjoyable.

"You can phone Logosol without fear of disturbing."
"As a customer, you can phone without fear of disturbing." Runo Johansson explains why he chose joinery machines from Logosol.
"The vertical milling machine is the best machine for an innovator. Here, I’m trying out angles and profiles," Runo Johansson says about the Logosol MF30.
Runo Johansson believes in his business concept. And he believes in it to such an extent that he did not give up even when his workshop burnt down to the ground. Now he has bought new machines from Logosol and got his business going again.
Runo’s business concept is built on the most important thing in the world: the photosynthesis. This is the process in which the energy from the sun helps green plants to turn carbon dioxide and water into food.
"We have to learn to work with nature instead of against it," says Runo, who early committed himself to environmental issues.
When he started to think about the environment it was considered bohemian.
Today, the reality has caught up with us. The Nobel Peace Prize was given to Al Gore and the UN’s climate panel. Our shared environment is now at the top of the agenda.
A room for learning
What distinguishes Runo from most of us, is that he goes further than talking and writing. He created a "room for learning" in which the prerequisite of life becomes evident and comprehensible.
It is a greenhouse with the name GrowPoint. The greenhouse is a selfsupportingand very strong latticework construction whose design seems to appeal to most people. Stylish, is a common comment.
Each building element is a triangle-shaped wooden frame with a transparent sheet of insulating polycarbonate.
These elements are put together into a geodesic dome. The construction has several advantages. It is prefabricated and thus easy to assemble. It stands wind and weather much better than conventional greenhouses, and it is fitted up both for plants and people.
"In 18 square metres there is room for about 5000 seed plants, a table and five chairs. The GrowPoint greenhouse is also a fantastic outdoor room," Runo says.
The workshop burnt down
Its weather resistance was proven when the storm Gudrun hit southern Sweden. The Swedish university of agricultural sciences in Alnarp has a GrowPoint greenhouse in its rehabilitation garden. The storm destroyed a lot, but on the greenhouse there were only a couple of ventilation hatches that were damaged.
The entire construction and its function is well thoughtout, but when the interest in it was about to turn into sales, something devastating happened. The production building burnt down to the ground. The entire stock and assembly of machinery was destroyed by fire. Among the things lost in the fire was a Logosol PH260 four-cutter planer/moulder and an MF 30 vertical milling machine.
A disaster of this proportion can make even the most enthusiastic person give up. But this is not the case with Runo Johansson. While waiting for the workshop to be rebuilt, he has rented a place in Limmared and purchased new machines:
"Choosing Logosol again came naturally. If you have any problem you can phone Logosol for support, and you are always treated professionally and friendly," says Runo.
This time, due to economic reasons, the assembly of machinery became slightly different. He bought the multi jointer/planer MH410, the table saw PS315, and also the, to him, indispensable MF30.
He chose separate machines instead of a combi machine, and this is Runo’s explanation: "The logistics in the workshop becomes much better when you have separate machines. A combi machine of the same quality is, strange as it may seem, more expensive to buy," says Runo.
The machine he appreciates most is the vertical milling machine. He uses this to try out angles and profiles before they are put in production. He also uses it for tenoning and routering. When he has found the right shape, he orders knives and starts producing in the multi jointer/planer which is also equipped with a side cutter.
"Two persons can operate the machine at the same time. One takes care of the jointing operation and the other planes and moulds.
I know that the four-cutter planer/moulder gives more possibilities and has more capacity, but the vertical milling machine is enough for the wooden details that I need," says Runo.
The GrowPoint is manufactured in a couple of standard sizes starting from 15 square metres. Due to the flexible assembly of machinery he can produce a great number of furnishing options and vary the design according to customers’ desires.
The first pilot series were made of aluminium profiles, but Runo soon changed to wood. It is a more natural material, which is appreciated by the customers. The building elements are made of pine heartwood, larch or oak. The goal is, as far as possible, to use timber from his own forest. This is why he has established a cooperation with a nearby company, Å-såget in Limmared. The next investment will be another machine from Logosol, the circular resaw KS 150. The circular resaw will streamline the processing of the beams that are made from his own timber.
Runo’s greenhouse includes functions, thoughts and ideas that would take several pages to describe.
Instead, we recommend a visit to the website of the company, www.growpoint. se. Finally, we give you a quotation, where Runo, in poetic form, summarizes the thoughts behind his business:
"If we create environments where butterflies are pleased, minds will be opened and mouths will be fed ". *
Imagination and Logosol SH230
– a Successful Combination
”When you yourself process the wood, you can allow yourself a little extra,” says Arne Karlsson, who has processed all aspen in the relaxation area, using Logosol SH230.
The window seems to be at the end of a tunnel. This is an optical illusion made of mouldings. The wall is level.

Take two creative persons and add a Logosol SH230.
The result is creative solutions, exciting choices of wood, and an extremely pleasant home. At least this is the case when the couple happens to be Arne Larsson and Marjatta Oksanen.
Arne and Marjatta have handed over the family business to the next generation and are now concentrating on feeling good. For this purpose, a piece of land was bought in Tryggeboda, near Mullhyttan, Sweden. It was completely covered with forest and bordered on Lake Multen.
”We hired a contractor who felled 700 cubic metres (915 cubic yards) of timber. We kept 150 cubic metres (196 cubic yards) and sold the rest,” says Arne. The timber we kept has now been processed by the Logosol Sawmill and Logosol SH230 into a strikingly beautiful house, both on the outside and the inside. On the inside all sorts of wood from the forest compete with each other in being the centre of attention in panels and mouldings. Here, there are panels of waxed aspen, varnished casings of pine, and doors of oiled elm for the wine cellar. But most eye-catching is the hexagonal relaxation area including a big sauna and a room for relaxation with a window wall facing the lake.
”All aspen is machined in the Logosol SH230,” Arne tells us. Panels and mouldings of aspen have been used with great imagination. One of the windows is framed by mouldings that overlap each other, creating the illusion of a tunnel. The walls are covered with angled panels, and the ceiling is made of squares of mouldings.
”Making things good doesn’t cost any extra when you yourself process the wood, and then it would be foolish not to,” says Arne. He is very satisfied with his Logosol SH230. It is easy to reset, easy to use, and gives a good result. That opinion is shared by the joiner Bertil Fahlström, who has lent a hand in the building and decoration.
"I used my PH260 for all the woodwork in the house"
Mr. Raymond Leroux.
I try to use the same profile knives for many products.
The bathroom is beautifully
Red Oak in the living room.
Mr. Raymond Leroux is the fourth generation growing up on his farm in Casselman, 50 km outside Ottawa in Ontario, Canada. He took over the farm in 1979 and is now working as a professional logger on the private woodlots in the local area.
"A modern harvester is too expensive for this type of forest," says Mr.Leroux, "so we work with conventional chain saw and skidder methods.
Farmers still find it economically beneficial to transfer forest land to agriculture land and we often get this type of logging. In this area, man made forests started early on. Today you can find nice stands that were planted 40 to 50 years ago.
Build a new house
There are some big trees around. I cut five White Pines but needed two truck loads to move them. There must have been over 5,000 board feet between those five Pines.
In May last year my wife and I decided to build a new house. After searching the market we decided to purchase a Logosol PH260 4 -sided planer moulder.
Through my work as a logger I have access to all sorts of logs, "tells Mr. Leroux. " I have a small sawmill and saw White Pine, Red Oak, Sugar Maple, Black Cherry. White Ash, Elm, you name it !
I extended my garage with a wood shop where I keep the PH260 and also dry my lumber. I heat the house and workshop with an exterior wood fired furnace.
The exterior of our new house is covered with White Pine Siding. To use the wood optimally, I used both 8 inch and 6 inch wide boards that I run through the PH260.
"I placed three 8 inch wide boards in a row and then a 6 inch wide board to make it look nice."
To optimize the use of the wood is an important factor for me, "says Mr. Leroux".
I can save a lot of money by doing so."
I made the deck from local Cedar that I rounded in the planer. I planed the boards when they were green but they did not warp at all. My wife and I decided to open a Bed & Breakfast. We put in three rooms with baths in the basement, that we will rent out. They look out over the 90 acre farm land where you often see deer feeding.
Our community has an outdoor summer theater and one problem has been for visitors to find a place to stay. Hunters are also looking for local lodging in the area during the fall. The Bed & Breakfast will be a nice complement to the income.
I used my PH260 for all the woodwork in the house, the Red Oak floor in the living room. For the kitchen floor I made narrow boards out of Maple.
More and more requests
The bedroom has a spectacular Black Cherry floor that will only develop into nicer colours over the years. I saved smaller cut-offs and used a few basic knife cutters for all the patterns to save money."
The bathroom is beautifully trimmed with shorter cut-offs from the wood work. Mr. Leroux hopes to finish the house within the next few months.
"The local building supply store phones me when they need custom work. I didn’t want to sell too much of my own wood until now as I needed most of it for the house. The word spread and I started to get more and more requests for using the PH260 planer- moulder," ends Mr. Leroux.*
Every plank, panel and moulding is made by Marita and Per
”When the piles of timber were at their largest point, we had to do as marathon runners and concentrate on one log at a time,” says Marita Lindgren. Marita and Per sawed around 70 cubic metres of timber using their Logosol Sawmill and then built their dream house.
Per and Marita Lindgren are townies and did not originally own any forest. The couple has four grown-up children and an old dream of building a house after their own ideas. When a property in the village where Per spent the summers of his childhood became for sale, the dreams began to take shape.
A M7 Sawmill and a two-cutter planer/moulder was bought from Logosol. Shortly thereafter, the storm Gudrun came, which felled large parts of forest in the north of Sweden, and suddenly there was more timber than they could take care of.
When everything was sawn up, it was about 70 cubic metres of timber. At the same time they started to build their house. Last summer, the dwelling house was built. It is a two-storied house of 190 square metres, and it is built in the same style as the old buildings in the village.
But why would two townies start sawing, planing, moulding and building themselves, when there are ready-made houses that they can buy? Well, this house becomes exactly as the Lindgren family wants it, down to the last detail. But the feeling of wholeness is just as important.
”To people of today milk is just a carton in the grocery store. We seldom think of the whole. If you are sawing the timber yourself, you are taking part of the entire process from fresh-cut timber to beautiful boards,” says Per.
The first time he read Fresh Cut he nearly burst with laughter when people in the magazine described the act of sawing timber as almost a spiritual experience. Now he is not laughing anymore.
”It may sound silly, but you can actually get a relationship with a plank.”
The building project has now come so far that the Lindgren couple has sold their house in the town in order to move to the house of their dreams in the country.
The Harpmaker Found the Perfect Tone in the Logosol Big Mill!
Harp builder Dave Kortier recently added a chain saw and Logosol Big Mill to his shop in Minnesota. "This mill is the perfect tool", he claims. "I can get everything lined up before the cut".
Dave Kortier´s harps have been sold around the world. "The internet has made the market a global business."
Building musical instruments requires extreme skill and precision. So what place does a chain saw and the Logosol Big Mill have in an instrument builder’s shop? Dave Kortier of Duluth, Minnesota has the answer. "I have always been involved in music", Dave explained. While his instrument of choice is a bassoon, he has repaired all types of instruments, and now specializes in building authentic reproductions of antique Irish harps. Recently he added a new tool to his shop—a chain saw and Logosol Big Mill.
By David Boyt
It started in 1991 when he met a local harp teacher, who complained that it was extremely difficult for her students to find suitable instruments at a price they could afford. Not one to turn down a new challenge, he used her harp as a pattern to build one, and immediately sold it to one of her students.
Dave now builds harps full time, in a variety of sizes and styles. "I build about thirty instruments per year," he says. Most of these are for students. Accurate reproductions of authentic Irish harps take much longer to build, and are more expensive.
The sounding boxes of the antique Irish harps were built from a hollowed-out block of maple or willow measuring roughly 5" thick, 18" wide an d 48" long. "I just couldn’t get blanks commercially," he recalled. The solution appeared in front of his house when he watched a truck from a tree trimming service haul off two huge silver maple logs. "I just stepped out the door and there they were on a truck. One was about 42" diameter by 8’ long, and the other was 36" diameter." Convincing the driver to leave the logs in his yard instead of hauling them to the landfill was easy. Now Dave was faced with the challenge of cutting soundbox blanks out of them.
The right equipment
"I started doing research, and decided that I needed a way to move the saw through the wood, instead of moving the log through the saw." Through an internet search he learned about Logosol, and decided that the "Big Mill" would do the job. He says that the video on Logosol’s web site convinced him that this was the right equipment.
His next task was to locate a suitable chain saw. "I had run a chain saw maybe ten minutes in my life", he recalls. Dave went to a local Stihl dealer, and requested the biggest chain saw they had. "They kept trying to sell me smaller saws before I convinced them to special order an 880 with a 36" bar." "This mill is the perfect tool", he claims. "I can get everything lined up before the cut."
Once he has a slab cut to the desired thickness, Dave traces around a template to mark the outline of the sound box, then cuts out the rough shape with a smaller chain saw.
"I feel really good about this [investment]," he says. "I spent about $2,000 on equipment to saw these two logs, but when I get them cut up, I’ll be looking for more." He should not have a hard time finding them. Many of the old silver maple trees lining the streets of Duluth are being removed.
Dave’s replicas of Irish harps are the product of years of careful study and research. In 2002, Dave traveled to Ireland to study first-hand some of the traditional harps. With the assistance of the Historical Harp Society of Ireland, he arranged to examine the Trinity College harp, the national treasure of Ireland. It is the oldest known Irish harp, built around the year 1400. "It was quite an honor to be allowed to handle it and examine it closely," he says. Dave has also examined a number of other antique harps housed in museums in Ireland and Scotland. This has enabled him to create accurate replicas of these harps.
Global business on the Internet
While Dave mostly builds for the U.S. and Canadian harp players, his instruments have been sold around the world. "The internet has made the market a global business." I have shipped harps to Ireland, Sweden, Austria, and Japan." One customer shipped Dave two blanks of willow from Ireland for her harp.
The internet is not the only modern technology to creep into Dave’s business. Strings are a fluorocarbon polymer plastic. In addition to the traditional harps, he now has an electric model with MIDI interface, allowing it to connect to a computer to produce the sound of any of 256 different instruments (including, of course a harp).
While chain saws and Logosol mills were not available to the original harp makers, there is little doubt that they would have put them to good use. Dave has demonstrated that modern techniques, combined with traditional craftsmanship can create instruments that accurately reproduce the sound and feel of these ancient treasures.
For more information, check his web site: kortier.com. It contains more photos of his harps, as well as information on purchasing the different models. The web site also contains sound tracks from a CD of harp music by Siobhan Armstrong, played on one of the harps he built from the Irish willow.
Both butterfly-nets and chainsaws are required to save the rainforest!
Timber waiting for shipping. Felling timber without damaging the forest is the key to environmentally friendly forestry in rainforests,” says Joakim Byström, who invented the Jungle Mill.
|Bengt-Olov Byström demonstrates sawing in the Solomon Islands.|
Logosol’s small-scale technology is still used to create more environmentally friendly forestry. Here is a photo from Peru.
|Mattias Byström, Logosol, is following bulldozer tracks in the jungles of Costa Rica.|
After a trip to the Solomon Islands Logosol developed the Jungle Mill, a sawmill that can handle large-diameter timber.
“This product is a tangible contribution to environmentally friendly forestry in rainforests,” says Joakim Byström, one of the owners of Logosol.
But small-scale technology is hard to promote in this context, and today the sawmill is mainly sold in Europe, the US and Russia.
The story begins in 1996, when the founder of Logosol, Bengt-Olov Byström, and his son Joakim were phoned by CDI, a humanitarian aid department within the EU.
“They had heard that we are good at small-scale wood processing and wanted us to help them develop a sawmill project in the Solomon Islands. We travelled to the other side of the world, and were welcomed by the Forest Agency of the Solomon Islands,” Joakim Byström remembers.
A revolution for the villages
The sawmill they already had in the Solomon Islands was not working well, the saw blade only had four teeth – the motor was not able to run more than that. Nevertheless, ”the Walkaboutsawmil”, had been a revolution for the villages out in the rainforest. Now they could saw the logs on the spot in the forest and, without using any heavy machines, carry out the cut timber to sell it. The alternative was to sell standing timber, and this alternative meant significantly less money to the villages and large bulldozers that damaged the forest when driving in to bring out the valuable trees.
Of course, the Byströms thought that the villages definitely should have had a Logosol Sawmill. And here an almost incredible coincidence happens. 200 metres from the sawmill in the Solomon Islands there was a local Stihl dealer, who had a Logosol Sawmill in stock!
“We had travelled 10 000 km and ended up 200 metres from a Logosol Sawmill! The Stihl dealer had got it from Australia and had never unpacked it. We assembled it and could straight away demonstrate what a revolution the Logosol Sawmill is for small-scale wood processing,” Joakim Byström says.
The Jungle Mill was developed
But rainforest trees are not like Swedish spruce. The Logosol Sawmill was unable to manage the large logs. Here they had a problem to solve!
”Already on the plane home, Bengt-Olov and I were designing a new type of saw – a lightweight sawmill with which it would be possible to cut really large-diameter logs.
The Jungle mill would open the door for environmentally friendly forestry in the rainforest.”
“We really wanted to do something about the problem, and the Jungle Mill felt as the best solution,” says Joakim Byström, who together with his brother Mattias registered for a course in tropical ecology to learn more.
The course was ended with a trip to Costa Rica. In the luggage the brothers had a Jungle Mill prototype and a Stihl 064.
”At the airport we met the other course members, botanists with butterfly-nets. And there we were with our chainsaw – it was a veritable culture clash,” Joakim says.
No support for small-scale technique
In Costa Rica the brothers tested the Jungle Mill, while the botanists were studying how the villagers could earn money from selling rainforest butterflies and insects to Europe.
“The Jungle Mill tests went really well, and we also became more aware of the destructive forestry that is going on in the rainforests,” Joakim says. “We also succeeded in convincing our course members that, if rainforest is to be saved, you need both butterfly-nets and chainsaws.”
That simple truth was, however, harder to promote in a wider context. The support for small-scale echotechnology turned out to be non-existent:
”It seems that environmental and humanitarian aid organisations either invest in democracy education or high technology, such as hydroelectric power projects. There is no interest in small-scale technology.
A big success in Europe
The Jungle Mill, which was originally designed for the large-diameter logs of the rainforest, became instead a big success in Europe, the US and Russia. But now it is used for cutting stubborn oaks, large-diameter aspen and huge spruces. Today, this sawmill is one of the packages that make up the Big Mill System, which Mattias Byström has designed. The Jungle Mill is now called the Timberjig, and it constitutes the base of the system, which can be adapted to the sawyer’s particular needs.
Anders is the New Record Holder
Logosol has held the world record for the longest plank for more than ten years. Double records, that is. But now the last record is beaten. In next year’s edition of Guinness Book of World Records the record-holder’s name is Anders Nykvist from Onsala in Sweden.
|The record was broken sooner than planned. Due to that, this is one of the few photos that show the event. The press of the world did not make it in time.
|With the help of five other sawmill owners and a total of ten Logosol Sawmills, Anders Nykvist succeeded in breaking Logosol’s world record in the event ‘the world’s longest plank’. The new record is 38.9 metres (127.6 ft).
It was Logosol that initiated the event ’longest plank’ in 1995 at Elmia Wood Fair in Jönköping, Sweden. According to the rules, which have been approved by the record book, the plank must be of the dimensions 2x4” all along the plank. The part of the plank that does not come up to the mark is deducted. Logosol’s first world record was a 34.1 m (112 ft) long plank. Two years later, it was time for another go when Logosol’s US office in Mississippi was inaugurated. The earlier record was surpassed by more than one metre (3.3 ft), and up to now the world record has been 35.2 metres (115 ft).
Since then, no one has been able to break the record. At Logosol it has been speculated if anyone else would be able to succeed. The guess has been that a new record would be set in the US, where there are much taller trees than in Sweden and they have the helicopter lifts needed for lifting the giant log.
What no one expected was that a guy from Onsala in Sweden would break the record after having seen the first record plank hanging in one of Elmia Wood Fair’s exhibition halls in Jönköping.
“When I saw the plank, I decided to beat the record,” Anders Nykvist remembers.
He worked as a carpenter on the East Indiaman Gothenburg, and took part in making the floor timbers, which were sawn with the help of a Big Mill from Logosol.
”I knew how to do it, and a couple of years ago I bought a Logosol Sawmill,” Anders says.
But one Logosol Sawmill is not enough for breaking any world record. And furthermore, you need a tree of extraordinary length. Anders works with felling trees in a residential area, and he knew of some really tall and straight spruces in Tulebo, south of Gothenburg.
”I contacted the land owner, who probably thought I was out of my mind. But he gave me his permission,” Anders says.
Then, he put an ad in the local paper announcing that he wished to get in touch with other Logosol Sawmill owners who were interested in lending him their sawmills to take part in breaking the world record. The newspaper thought the idea was so funny that he was allowed to insert the ad for free. Some twenty Logosol Sawmill owners announced their interest.
When everything was pieced together, Anders contacted the record book, and they were interested in sending out a controller. The intention was that the preparations for the sawing should be made in good time, but when the controller phoned at the beginning of May in 2007, Anders had to skip that plan.
“It was a Friday, and he asked what I had planned to do the day after. He was in Gothenburg and thought that it was about time to saw the world’s longest plank,” Anders says.
He accepted the challenge, and the same evening he went out to fell the record spruce. The sawmill owners were contacted again, and at six o’clock in the morning, on Saturday the 12th of December, there were ten Logosol Sawmills and five sawmill owners at the site in Tulebo. Anders had prepared himself by cutting new aluminium profiles into lengths, which were then used for rebuilding the sawmills. He removed the lifting devices from the sawmills and joined the guide rails together. What was left was a 50 metres (164 ft) long guide rail, which was placed on the road, and then adjusted straight with the help of a string.
The tree was lopped and lugged out in the road with the help of a tractor and an excavator. It was placed on a number of garage jacks beside the guide rail. The preparations took four hours, and ten o’clock in the morning the sawing of the first slab began. The cut was taken deeply in the log so that the first board would come in the centre.
“We cut the slab in one metre (3 ft) long pieces to be able to lift it away,” Anders explains.
In the next stage, the log was lifted up with the garage jacks, and a four inch beam was cut out. The beam was then turned over, resting on the part of the log that was still lying on the garage jacks. After this another slab was cut from this beam, and finally it was time to cut the record plank.
“I wore out two chains before everything was finished towards evening. Since we had dragged the log on the ground, the bark was full of sand and dirt,” Anders says.
The plank was well over 39 metres (128 ft), but on the last part of it the measurement was not correct. The accepted part of the plank measured 38.9 metres (127.6 ft), which will be the new world record that Guinness book of records presents in the edition of 2008. And the record holder is Anders Nykvist.*
”Circular sawmills are not complete without a Rip Saw Assistant. The sawmill becomes both safer and easier to work with,” Yngve thinks.
Never cut again without the Rip Saw Assistant
”A sawmill is not complete without a rip saw assistant. I am one hundred percent satisfied with this treasure,” says Yngve Karlsson who has a forest property and a circular sawmill of the type Laimet 100.
Two years ago he bought Logosol’s Rip Saw Assistant. It was left in its package half a year before he had time to assemble it. His advice to other circular sawmill owners is that they promptly order and mount a Rip Saw Assistant.
”I can’t be without it. Since the Rip Saw Assistant was installed I haven’t even once climbed up on the saw table. This is the best you can do for safety.
To his wife Gudrun, safety is most important.
“I’m always worried about Yngve when he’s working at the sawmill. It’s good that he thinks about safety,” she says.
For his own part, Yngve thinks most about the safety of his sons, who also use the sawmill and in course of time will take over. One of the sons took the initiative to buy the Rip Saw Assistant to make his father’s working situation safer. From the Karlsson family you can learn that the safety given by Logosol’s Rip Saw Assistant concerns everyone, not only the one who is sawing.
10 years with the PH260!
This year, Logosol’s four-cutter planer/moulder celebrates its 10-year anniversary. You could read about this occasion in the last issue of Fresh Cut.
The constructor Bosse Mårtensson means that in most cases PH260 is better than a large industrial planer!
At least when it comes to small-scale wood processing.
– PH260 is better than industrial planers when it comes to small-scale wood processing, the constructor Bo Mårtensson says. His company manufactures both PH260 and CNC-controlled machining centres for joineries.
PH260 is celebrating its tenth anniversary. It is better than industrial planers at professional small-scale wood processing.
There are few four-cutter planers/moulders that are as spread over the world as PH260. Today, it is mass-produced in Östersund in Sweden.
"There are few planer/moulders that are as spread over the world and used under as varying conditions as the PH260. It has proved itself to be durable and easy to service and maintain," says Bo Mårtensson.
The development of PH260 started in 1993. Bengt-Olov Byström, founder of Logosol, was in the process of drawing up the outlines of a planer/moulder that would have the low price of the SH230, be easy to use and give high-class results. He met Bo Mårtensson at a trade fair, and their cooperation resulted in a small, innovative four-sided planer/moulder.
Logosol launched PH260 in 1997. Consequently, this year the machine is celebrating its tenth anniversary.
The statement that PH260 is better than a large industrial planer when it comes to customized producing of building timber and mouldings, is well founded. Here are the proofs:
1: The size.
PH260 does not require large premises. Fit wheels on it or place it on a pallet and move it away when you are not using it. Industrial planers require concrete foundation and heated facilities.
PH260 is reliably rust protected and stands condensation. You can use it outdoors and store it in cold rooms. Industrial planers are built for standing in the warmth, and contain parts that rust.
3: High efficiency – low amp.
Even though PH260 has a total continuous output of 12.2 kW, it only needs 16 amp fuse, 400V three-phase. There is enough electricity in an ordinary private garage. Industrial planers require 63 amp, which costs a small fortune just for the connection and the standing charge.
Everything is gathered under one raisable protective cover. You can see and have access to the whole machinery without difficulties.
5: Large dimensions.
PH260 manages to process thick and wide boards. The planing width of an industrial planer is normally 160-230 mm. PH260 can process 260 mm wide work pieces. PH260 also surpasses industrial planers when it comes to handling thick work pieces, since it can process pieces that are 230 mm thick.
6: Better result.
Quite contrary to what many believe, a small cutter gives a better surface finish than does a large cutter. The reason is that the board springs every time the knife enters the wood. A larger cutter produces more springing. The less springing the better surface finish. The limitation of the small cutter is the feeding speed, but when producing on a small-scale basis it is more important to have a high-class result.
7: Simpler to mount knives.
It goes without saying, that a small planer/moulder is easier to set up than a planer/moulder with large cutters and many knives. The largest industrial planers require a crane when knives are to be replaced.
8: Smaller working radius.
All wood becomes more or less bent when it dries. In a long machine the boards are forced straight during the machining, otherwise they do not become parallel. Long boards cannot be straightened, since they then become pointed at the ends. A short distance between the cutters makes the board wriggle its way through the machine, and by this it becomes parallel.
9: Lower cost.
The price label on Logosol PH260 speaks for itself. In reality, PH260 becomes even more advantageous than a second-hand industrial planer. It needs less and cheaper tools, it does not require any conveyor belts and no special-built house. Not to mention the spare parts and the maintenance, which only cost a fraction compared to an industrial machine.
10: Stable construction.
Everything is bigger on an industrial planer. It is easy to believe that this makes the large planer more stable. But PH260 is very stable by its construction. The cutters in an industrial planer are suspended on one end to be easy to replace. The cutters in PH260 are suspended on both ends. The difference can be compared with holding a rolling pin with one hand or with both hands.
A REAL PRO MACHINE
An increasing number of owners around the world can add more advantages to this list. But on one point there is no difference between PH260 and new industrial planers.
"The components are of the same quality. PH260 is a pro machine, only it’s smaller," Bosse Mårtensson states.
2 600 metres of planed 8 x 12 inch timber
What do you do when the building material you have consists of 2600 metres (8530 ft) of timber, sawn from large-diameter logs and by three different methods, with different surfaces and varying measurements?
“The only solution was to plane the whole lot,” says the timberman Per-Arne Ragnarsson.
– Per-Arne Ragnarsson and Peter Hall are building a log house of 270 square metres.
Building a house of 270 square metres is an extreme project, even for an experienced timberman as Per-Arne Ragnarsson.
Peter Hall is the customer, and he owns a Logosol PH260 four-cutter planer/moulder.
This is the photo that Per-Arne took with his cellphone , showing the planing of a 12 metre long beam with the measurements 8’’ x 12’’.
Per-Arne makes a living by renovating and building log houses, and manufacturing windows. He lives south of Vetlanda in Sweden. At the moment, he is building a log home of 270 square metres (approx. 2900 ft2). The customer’s name is Peter Hall, and luckily he owns a Logosol PH260 four-cutter planer/moulder.
Grind the knives often
"The logs were cut with chain, circular saw blade and frame saw. It would not look good with all the different sawing surfaces," says Per-Arne.
He phoned Logosol and asked if it is all right to use the four-cutter for planing beams that are up to 8 x 12 inch. The answer was "Yes, if you know what you are doing". Per-Arne knew what he was doing and went ahead with the project.
A couple of days later Logosol received an e-mail. It was Per-Arne who sent a photo he had taken with his cellphone showing the planing of a 12 metre long beam with the measurements 8’’ x 12’’. The photo had the accompanying text: "Sending a photo of how to use a PH260".
It almost looks unreal when such a long and thick beam comes out from this relatively small planing machine.
It was not only this beam that was planed. Altogether it was 2600 metres of the dimensions 6 and 8 inches. The only problem was that large-diameter timber of this size often has sand and dirt in the wood.
"You have to have double sets of knives and grind them often," says Per-Arne.
Sawing is relaxing
Building a house of 270 square metres is an extreme project, even for an experienced timberman as Per-Arne. Normally, he works with smaller houses and produces the timber on the spot using his Logosol M7. When he works on commission he uses a petrol chainsaw; at home he uses Logosol’s bandsaw, about which he has only good things to say.
"It works really well," he says.
Per-Arne also runs a small joinery shop in which he manufactures windows for his house projects. Here, too, his home-cut timber comes in handy. In addition, the Logosol M7 has another advantage that is appreciated by a craftsman.
"Sawing is relaxing, somehow. And furthermore, I can beat any sawmill when it comes to measurements and surface of the timber, says Per-Arne Ragnarsson.
