Out of curiosity, has anyone had problems with new but relatively old sanding belts failing at the seam? I hadn't used my 4x24 belt sander in quite some time but I had a stock of belts on hand. I had 4 Klingspor belts come apart at the seam within minutes... the belts were barely warm and the grit was not clogged. The joint strip separated from the belt itself. I have some Sungold belts of the same vintage and they stayed together.
Anyhow, anyone else run in to this problem?
