I don’t use my bandsaw much. In the last year or so I could not cut a straight line, I pretty much ignored it. So a project came up where I needed it, I decided to try and figure out what was wrong. Turns out it was an easy solution. One of the lower bearings had fallen off and I guess was vacuumed away. I had a new bearing so the issue was only the bolt holding the bearing which I guess was also vacuumed away. It’s a Craftsman so the required bolt was no longer available but the Rikon one , basically the same machine, was. I ordered it, cost$.79 plus $11 shipping. Best $12 I ever spent and now it works fine.
