I recently got a used Jet 18" bandsaw and when I tried it out before buying, it sounded fine. When I got it home now thought, there is a clunking sound.
I've isolated the sound to the lower wheel -- I disconnected the drive belt and removed the blade and can recreate the sound by manually turning the lower wheel. The clunk does not occur at the same wheel position every time.
Any ideas? Could this be a bad bearing?
