I was checking the alignment of my JET tablesaw today, and noticed that
the blade (WWII)was cupped quite a bit (at least 1/16") when I tightened the arbor nut. I think the problem is in the arbor flange (the one next to the nut); it seems like it was incorrectly machined and forces the blade to cup whenever I tightened it.
I assume getting a blade stabilizer would help, but I want to first fix
the arbor flange problem if it is indeed defective. Any ideas or suggestions?
