A Homebuilt Chainsaw Mill And Band Saw Blade Speed Information

So today, as they say, is a day of rest. Stiflingly hot and humid today lots of icy cold drinks have helped but that means no power tools or welding arcs, lol.

So fortunately I get to play on the computer. I will start off with a nice article on sawmill band wheel speed by Timothy Cook. Mr. Cook runs a sawmill supply and sharpening service and shares his lengthy experience answering questions on his web site. Here is his answer to correct sawmill band wheel speed, very informative.

With a 3.15" pulley on my motor, I will be running at 4230 fpm, which sounds good to me. 

The next article is a nice build document on a homebuilt chainsaw mill. I first saw this article on the site. It was published with permission from T J Brown's (the builder) site, I turned the article into a resized pdf. Their are some ideas here that influenced my build. This is unique in that it combines chainsaw mill and band saw mill ideas into a  unit that is not normally seen.

To download the 28 page article click Homebuilt Chainsaw Mill. Here are a few pictures. Money wise a good quality, large chainsaw will cost more than I paid for my 15 HP motor, but the simpler arch assembly might be more desirable for the woodworker who does only the occasional milling.

Book Review: Chainsaw Lumbermaking by Will Malloff

As mentioned in the previous post this is a review of Will Malloff's great book "Chainsaw Lumbermaking" published by Taunton Press in 1982.

Will Malloff has a lifetime of experience on the subject and has a number of patents in the field including the development of the ripping chain tooth geometry. The book covers all aspects of chainsaw lumber making and it's easy to see the knowledge that only hands on experience can bring. Will will take you through choosing and maintaining your saw to operating a commercial mill (like the Mark III Alaskan Mill) to making your own mill and lots of plans for making your own tools and accessories.

I was aware of this book for a while, from my Fine Woodworking magazines, the price made me wince though. So you can imagine, my heart almost skipped a beat when I walked into a great little used book shop in Belleville Ont. in 1994 (yes I can still remember that far back lol), and there it was on the shelf, hardcover edition, in new condition, with a used price of $10. If my body was 20 years younger I would have done back flips lol.  Here are some pictures. Click on the images to expand.

Here are a couple more pictures of the 2x4 mill in the previous post in use.

The back cover.

If you like the subject matter and you come across this in the used market, snap it up you will not regret it.

Well it's supposed to hit -48*C with the wind chill tonight, can,t feed the wood stove fast enough lol.


2X4 Chainsaw Mill And 12" Cupola

So from my project binders comes 2 more plans. The first is a easy 2 x 4 chainsaw lumber mill by Will Malloff. The plan is a compressed version of the plan in his book (see review above) "Chainsaw Lumbermaking" and comes out of Fine woodworking magazine. Both are published by The Taunton Press, the editor included the article in what is basically a book review. Here's the article, there are more details and pictures in the book.

 The second plan is from Mechanics Notebook # 12 reprinted by Lindsey Publications. As mentioned in a previous post this is another cupola plan. This one averages out to 12" bore below the stack outlet. This one is unique in that the working section can be rolled out from under the stack section for cleaning, repairs and even charging for a short run. It has a drop bottom making cleaning even easier. For the small user you can skip the charging door and charge with the working section pulled out and melt up to 400 + lbs of iron per charge. For a small outfit in the casting business you can use the charging door and melt 1500 lbs/hr. on a continuous basis. Truly a nice well thought out design. His suggestion that larger cupolas have there bore reduced by adding temporary refractory, in order to reduce there capacities, in times of economic downturns, is exactly what was done during the thirties depression and subsequent downturns.
