Glad to hear that the belt worked as advertised. Sorry you have had so much trouble. I have the same sander and mine tracks fairly well but needs minor adjustment as I'm working with it. The guy I got it from had a lot of trouble with it when he got it and burned through several belts and had trouble with drum alignment. He was a segmented turner and used it for flattening his rings and if they were not perfect he was not happy. By the time he died and I got the sander he had worked out all the bugs. His wife even found an extra new belt about a year later and gave it to me. I don't use it all the time but when I do it's often for quite a stretch. Great machine overall. I often use it to clean up and reclaim old or dirty material.
