ps did you run into rocks and how was the blade after cutting?
I bumped a few. You can see in the last picture if you look close I have a tooth or 2 pretty bad out of set, but I was still cutting good just leaving a scratch mark on the face. For some reason when I first started I was having gum problems on the blade and it was diving (rising hard actually ). The blade was sharp, just balling up with wood on the teeth. I guess it was because I am cutting with the grain, cross grain and everything in between. I cranked the tension down to the max and put some dish soap and water in the lube tank and really poured it on sawing, it fixed that problem.
I expect to hit a few rocks, but they should be on the leaving end not buried. I saw mostly yard trees...so as much as it makes me frustrated I am used to changing blades prematurely, I am like an Indy pit crew with as much practice as I get.
I may cut some thinner stock (?), but I have to saw on it some more. If I am changing blades every 4-5 cuts...4/4 just won't work. 10/4 is a safer bet first go around. This all an experiment to me. I think I have a market for the thicker stuff already, I have plenty of 4/4 figured stock to sell.
