A while back, in anticipation of more log milling, I made a jig for holding the chainsaw level along the length of the cut. This is basically a homemade version of an ‘Alaskan Sawmill’, with a few changes. Since I processed last winter’s log recently it made room for another in the drying area, so I finally had a chance to test out the jig this weekend. For the first cut a ladder is secured to the top of the log to establish a reference surface.
I opted on not tie the reference block into the end of the bar, since I have a limited bar length. Because of this, I also couldn’t make the reference block adjustable without introducing too much flex. Instead, I set it at the maximum board width I may need, and for all thinner boards I’ll add more wood to the block or log to shim it. This also gives me the ability to cut from both sides for a log that’s up to ~2x the bar length.
Altogether this test seemed to work great, the cut was extremely flat compared to the previous log that was cut free-hand. It was fairly slow-going though since I was using a standard chain; I have a ripping chain on order that should cut faster with the grain, I’ll install it before finishing this log.
