I built this Alaskan saw mill out of bed frame with my new Mig Welder. I maximized the width to 16”. The method is to find the center of the Log and make a sharpie mark, measure up enough so you get solid wood and make a sharpie mark with a level, measure up and do the same on the other side of the log. I then screw angle iron to the log on this line (I screw the angle and check with the level again and adjust with the tap of a hammer). Then I screw 2×4;s across the angle iron. Set the saw mill to 5 inches (enough to clear the angle iron) and make first cut, this makes a flat surface. You now set the mill to desired thickness, I used 1”, then start cutting, after a couple of boards I check to see the cut is flat and not twisted. If cut needs correcting, I screw the angle Iron on again to correct the cut. To check for a twist I use the 2×4’s, one on each end at 90 Deg and eye the boards up like winding sticks. I did some research on how to sharpen the blade for ripping; I cut the rakers down to .045” to make a deeper cut and changed the cutting angle of each tooth to 5 Deg. I can cut 16” wide 8’ long in ~8 minutes. I let the saw idle for a minute or so and then let it cool down between cuts As I cut I count how long it takes for the mill to pass over a knot or other defect (1 Mississippi, 2 Mississippi ….), as the blade dulls the count increases and I know it’s time to re-sharpen. I re-sharpen with a dremel without taking the saw out of the mill. As you can see from the pictures I have lots of wood, I actually have 6 logs total now. I painted the ends with latex paint to limit the splitting and covered to keep the rain off. Since taking the pictures I have added additional support under each stack, so the max span about 24”. I have lots of plans for this wood, I would like to make a bedroom set, similar to the night stands that I have pictured in a previous project. I also made a timber jack or peavy so I can roll the logs (last picture). I made all the logs longer then 8’, I used 9’ 2×4’s, this way when the ends split I can still have 8’ Boards. These trees are from hurricane Sandy, they have been down since 2012, I didn’t cut the tree so I had no splitting, the sap wood was a little soft, but the wood was not rotten.
