Built this sawmill so I could mill small logs into lumber. I got the idea from Mathias Wandel at www.woodgears.ca. I baught his plans for the 16” bandsaw and built and after seeing how he used one as a sawmill I thought about something similar. I wanted it to be similar to the lumbersmith sawmill http://www.lumbersmith.com where it is small and portable. This saw can be broke down with only a 7/16 nut driver. It will fit easily on my trailer. It will fit in the car also with the rails between the seats. Total weight of saw only is about 150 Lbs. However once dissassembled the heaviest piece is the motor.
Its built primarily using scrap 2×6 lumber and scraps from my scrap bin. I did buy plywood for the wheels.

I felt it needed water cooling but after using it for a while I realized my blades cut just fine without it. So I took it off.

I also thought I needed a log holder that would swing up and hold the log but after using it for a while I decided to stick with the type that slides into the T-slot bed as they work fantastic and the log hasn’t moved on me without them. So I removed the swing up one. In these photos the log didn’t mill well either as it had allot of knots and my left wheel axle mount wasn’t completely straight so got blade wander pretty bad (blade was getting dull also). That has been fixed with straight axle mount.

The left axle mount needed some work as it kept tilting slightly causing the blade to run on the edge. So after some adjustments and adding an adjuster it doesn’t move and the blade runs true.

To raise and lower the sawmill you just loosen the clamp and crank the handle on top. Each side needs to be cranked separately. Since I used 1in threaded rod it goes quick.

The right wheel alignment is exactly like the one Mathias Wandel did on his saw and it worked great so I used that design.

The wheels are 13 in. made by glueing 3 layers of 11mm ply and then milling them with a crown on the router table which I tilted at 5 deg. I didn’t put the rubber inner tubes on them as I felt they would fly off with the high speed. No slipage and they work great. I didn’t take a picture of the wheel on the router so here is a picture of the 16in wheel I made as it is same process. Note the bearings and axle are already in the wheels for this process.

The handle has the switch on it so it is handy to use. The handle is easily removed by just lifting it off the tennons on the legs. To remove the legs I just remove the lag bolts.

In this last picture I cut a 50in long Hard Maple log that was 14in wide. It cut great without difficulty.

I got the blades from R & D bandsaws http://www.tufftooth.com for which I got the Ripper37 blade with 1.3 tpi.

Cost to build was approximately $300 plus $160 for 7 blades.

Not sure how long it took as I didn’t keep track of time. I would say between 70 to 100 hrs.

Here is my blog on it. http://lumberjocks.com/geekwoodworker/blog/42700

Here is a short video of it in action although not very good video skills. https://www.youtube.com/watch?v=K2wLdhZjKBM

Specs:
Frame Width = 48 in
Height = 52 in
Log rails with bed = 96 in.
Blade = 105 in x 1 in with 1.3 tpi
Max log cut = 24 in wide x 72 in long
Max slab cut = 19 in.
Motor = 2 hp @ 3450 rpm , 220 volt
Wheels = 13 in.
Speed = 4400 fpm.

UPDATE…..
As of June 2015 I have milled about 3000 bdft of lumber and the saw is still working great. My dad has some white ash trees with the Emerald Ash Borer in them so lots to still cut.

Hey that turned out realy nice!
Seems to cut fast. Like the simple design and the fact that you built almost all parts yourself.
Not that i have any trees large enough to make timber but after seeing a project like this my first thought is “i need one like that”..

Thanks for sharing!

Hey Sean,

That is just a sweet project. You did a great job.

I think that I read in your blog that you were questioning whether the motor is large enough. After a couple shakedown runs, any sense at this point?

Thanks.

Greg
