I gotta be honest, my limited experience with Alaskan Milling, I never thought of the tapered setup like that for siding! I love it man! Super cool project! Chainsaw milling is a lot of work but super cool to have as an option. Will be watching to see the progress Wooly!
I think an adjustable shoe on the power head side, and a 3/4 to 1/4 thickness would be the zone to achieve! Also don’t cut from just one side of the log, so when you cut down the left side of the log turn around and cut back on the opposite side. This will help keep one side of each cut flat on the top surface of the log, & yield 2 planks with two cuts without having to roll the log! Remember , when cutting lumber, your kerf of the saw toot needs to be added to the thickness of the lumber desired, so if you are cutting 5/4 thickness it will be 6/4 or 1 1/2 inches thickness on the saw, then it will run through a surface planer to smooth each side of the plank down to 1 inch thickness or shall I say the ruff cut 5/4
Isn't there any chains that are used for cutting along the grain? It would be easier for the chainsaw... I know that there are such hand saws but I don't know about chainsaw chains....
