Bandsaw problem...wavy cut
I have an older (20 years??) Grizzly 14" bandsaw and I'm having some real problems tuning it up. I've gone through all the basics (checked for co-planer wheels, checked that the wheels are round and true, adjusted the guides, and even thrown in two new blades), but I can't seem to get a clean cut. Right now, the cut comes out very wavy. Almost like the blade is moving left and right as it cuts. Eyeballing it, the blade does seem to wobble a bit, but I don't know if that's just me searching for a problem or not.
Anyway, I'm stumped. Any ideas as to how I could try and fix this?
