Seems like we just replaced the V-belt on our SP-15, the one with the newer Baldor motor. It is already loose again. The last time we had belt issues, Lad Boyle wrote about a process he had for removing the bottom plate, the plate the motor sits on. I think this was so my machinist could make slots for the motor instead of holes, which we have now. The slots would allow us to move the motor slightly to tighten the belt. Am I remembering this correctly? Is it normal for such belts to become loose after only a few months?
