Several months ago I bought a used Buffalo 14” bandsaw ( my first bandsaw). In the process of refurbishing it I’ve put on new tires, new cool blocks, blade guide bearings, and new blades. Now I can’t get the wheels co-planner. I can get the top wheel’s upper and lower edges in line with the lower edge of the bottom wheel but cannot get all four edges aligned. The upper edge is about 1/16 (or less) out of alignment. The then comes off in only a few hand turns of the wheels.
