Lazyman, I haven’t check the individual teeth on the blade for misalignment. But this actually is the second Forrest blade that I tried. The first one was so bad, and sent it back (via Amazon) for a replacement blade, and then went through more tune-up steps, with pretty much the same result. Good idea, though, and I’ll take a look.

I am using a feather board. And I do use a blade stiffener, and the runout was so small, I don’t that the flange/arbor is the problem.

The mystery is why the scratches are only at the bottom of the cut…perfectly smooth at the top of the cut. I put a lot of weight on the board to make sure there was no vibration. The cuts are perfectly square, too. Could it be saw vibration?
