First step: checking out, if the wheel fits the lathe 😛 This bandsaw did a great job for about two years now, and if the wheels couldn’t be trued up on the lathe, I would have kept the things as they were. As you see on the image, it worked!
Measuring the upper and lower wheels resulted in a light offset of the whole surface. Not that much, but as the wheel was on the lathe, this was a short thing to fix.
