Rant: fixing my bandsaw blade drift nearly cost me a whole Saturday at the shop
I spent almost 5 hours last Saturday chasing blade drift on my old meat bandsaw, and the fix turned out to be a 40 cent bearing I had sitting in a drawer the whole time. I kept messing with the guide blocks and the tension, read every forum post I could find, and even re-squared the table twice thinking that was the issue. Turns out the lower wheel bearing was shot, which let the blade wander on every rib rack I tried to break down for the case. Swapped it in 10 minutes and the cuts ran dead straight on the next 3 primals. Any of you deal with drift that traces back to something dumb you overlooked at first?

Don't you think calling it a meat bandsaw matters here? A wood saw and a meat saw are set up pretty different, and that lower wheel bearing gets way more abuse on a saw that's cutting through bone and frozen primals all day. On the wood side, drift usually comes back to the guide blocks or the fence not being set right, but on a meat saw the wheels and bearings take the beating because of all the moisture and grit. So yeah, the 40 cent part was the real fix, but the reason it failed is probably that nobody ever pulls those lower wheels to clean and grease them.

Could the motor pulley be misaligned and pulling that wheel sideways?
