Portable saw mill

http://youtu.be/2D3_901kV54
Chainsaw sawmill from Logosol using Stihl chansaw. Portable like an Alaskan mill but with extendable aluminium guide rail that definitely increases the precision and milling possibilities.
Great fun for woodworkers.
There are more amazing tools on Logosol´s website. Perfect for DIY.
--------------------
Design seems simple and sturdy, always good signs.
A few starter tips for the worriers, since it seems that is their level.
For extensive use, quality chains. Make sure the chain gets oiled. Check that the chain tension is correct. Try to avoid getting the logs covered in sand\dirt. Make sure you begin the cut without skipping. Make sure you are not applying too much force. Cut in such a manner that the log do not trap chain and blade. Sharpen chain before the smoke start rising.
--------------------
someone actually makes an oiler that attaches to you bar over the front oil hole that when filled with bar oil, drips it into the hole for constant oiling of the chain... that and a good quality ripping chain should do you well!
--------------------
It is faster than getting hold of a lorry, load the log, drive it to the sawmill, unload the log, let the sawmill saw the planks, load the planks and drive the planks back home. Cheaper too.
--------------------
Canadier??I don't know how it cost in USA , but i do know 2 guys that cost 350 $ per day ( a full 8 hours of working ) and they can procede a minimum of 200 4X8X12 feet long plus 16 8X8X20 feets long plus 30 6X6X20 feets long in a single day ( all this for a structure of a small home pieces on pieces 20X30 with a second floor and the 6X6 are for the roof trust . it's not expenssive 350 $ for all the structure of a house , my father give me the trunk so they are free
--------------------
Use a ripping chain
Somebody needs to make a thinner titanium saw blade for this. Chainsaw blades are rather thick, it would waste less wood, cut faster, and place less stress on your chainsaw.

The Story of the Unplugged Sawmill

15 December 2011 kl 11:46

This year it is the tenth anniversary of the Logosol Sawmill model 7.  Logosol celebrates this by taking the next step in development, the M8. But what happened on the way here?
1989. The Logosol Sawmill was introduced for the first time in 1989, on the exhibition Elmia Wood. It struck like a bomb. At that time a mini-sawmill was actually a large piece with a wood bench and ignition bulb motor. Or with a very large electric motor that depended on high-amp fuses.
     The first Logosol Sawmill was an “unplugged” sawmill. No cord, and with a big petrol powered chainsaw running it. The saw unit was by far the biggest chainsaw on the Swedish market, Stihl 066. The world’s most sold chainsaw received Swedish type approval because Logosol started to sell the Logosol Sawmill.
     As all Logosol Sawmills, the first one was also lightweight and very portable. It was designed to make it possible for one person to lift it onto the roof of his or her car, drive it to the woods and cut timber there on the spot. The sawdust was left in the woods, and you could drive back home with sawmill and timber.
     The sawmill was not bound to any specific place and over the years it has been transported by air as hand luggage, tied to pontoons on seaplanes, and so on.

1990. Model 1 was made of standard aluminium profiles, screwed together like a big Meccano construction. Fascinating for those who like building kits, complicated to others. Due to this the M2 was introduced already in 1990. It was then the guide rail, which is still in use, was designed. By using aluminium profiles made specially for the purpose, the sawmill became simpler to assemble and its length was increased to five metres.
     During the 1990s new models were introduced every second year and the number of accessories increased. When the M5 came, all development potential was exhausted. The work with developing a new generation of sawmills begun. The M5 is the ultimate sawmill of the original type, and is still being manufactured.
     The 066 became the present Stihl MS660. It is still the world’s most sold professional chainsaw. Extremely reliable, and almost impossible to wear out. It does its job during many years, on the sawmill and when felling trees in the forest. In addition, it is a workhorse on the woodyard.

1993. The old village sawmills disappeared one by one, and the need for stationary sawmills grew. Modern circular and band sawmills were unreasonably expensive. The demand for an improved Logosol Sawmill increased. It already started in 1991 with extensions for the guide rail of the Logosol Sawmill. In 1993 came the first electric saw unit, E5000.

1995. The most common objection to the Logosol Sawmill was about the wide sawing kerf. In practice, the difference was minimal compared to a circular sawblade, especially when considering the fine and smooth sawn surface. If you plane off the defects that the surface gets when being sawn by a circular sawblade, the difference in material loss disappears. But Logosol chose to listen to the customers’ demands for a narrower kerf. In 1995 the first bandsaw unit, BS320, was introduced. Initially, it was a sensitive machine, but after years of improvement it has become a reliable workhorse.

2001. The Logosol Sawmill model 7 is introduced, 5.5 metre long, wider, sturdier, and with more accurate height setting. On older Logosol Sawmills the height is adjusted with the help of lock pins. On the M7 the log beds are raised to the sound of clicks by using a crank. One click is either 1/8 or 1/4 inch, depending on the setting. With the M7 came more accessories to make it possible for everyone to build a sawmill that is perfect for his or her needs.

2011. Now model 8 is introduced. It is described in the article next to this. The Logosol Sawmill M8 is the combined unplugged and stationary sawmill. Perfect out in the woods and at home on the backyard.

New Logosol Sawmill Gives Further Possibilities

6 December 2011 kl 12:01

For the first time in ten years, the wood-processing company Logosol presents a new Logosol Sawmill. The model passes under the name of M8 and includes a number of new modifications. Comfort and performance have been further raised. A new design gives the small sawyer more possibilities for both efficiency and job satisfaction.

“Not milling is like leaving a sack of money out to rot”

10 August 2012 kl 11:16

Recently we heard from one M7 owner who had collected a bunch of logs in anticipation of doing a lot of milling, only not to have time to mill up the logs until 2 years later. Rainer Kern called to tell us what he found when he cut into some hardwoods that had lain in place for several years. We discussed the value of spalted wood, and we sent him some reference material on this kind of wood to help him realize what he had found in these old logs. Here is his story:

Trailer makes it easier to handle storm-felled trees

3 April 2012 kl 11:27

It is wise to remove the trees that were felled by the strong winds this winter, otherwise there is a danger of insect infestation in the wood.
But how can you easily transport individual trees over logs and rocks?
Logosol has the solution, a smart log skidder trailer for four-wheelers.

Young People Realize their Dream of Living Close to Nature with Their Own Sawmill

12 March 2012 kl 12:55

In Sweden the trend is evident: Young people become more and more interested in crafts of the old times and dream of a life in the country.
Three of those are Johannes Kabell, Timothy Ohdin and Per Hansson.
They have started a crafts collective and are building a large workshop with the help of their jointly owned sawmill from Logosol.

MAN! that's some fine dust! Is it a hard-as log, blunt, or just standard chain? hard to tell with such a short vid, with a mill your wasting your time without the right chain, bare minimum it needs to be sharpened at 10 degrees, sometimes 0, also skip tooth makes a huge difference, especially on wider cuts, (reduces powerhead load,+ more gullet per tooth) on softer- cleaner logs you can go with square grind as well to speed things up, but i just like a semi chisel skip tooth with 10 deg. grind

Husky 3120 and Stihl MS880
both have around 122cc ...and one has a tuning up to 10hp
-------------------
slabbing is hard on the saw, even for pro saws. They run at righter carb settings, use more bar oil and have a skip-tooth or ripping chain. This cheap consumer model saw will die quite quickly..
-------------------
Ripping requires a special chain and a powerful saw. This guy is burning his way through with friction. Save your money go to your local lumber yard.
With the Logosol Sawmill M8 you can quickly produce high-class planks and boards from your logs, in the length and dimensions of your choice. The sawmill is simple to use -- and easy to own.
