I recently bought a used Grizzley Disk/Belt sander that uses 6" X 48" belts. The guy threw in half a dozen new belts. I have now had 4 of the new belts snap at the lap joint. I have tried the tension quite low, just enough so the drive roller doesn't slip (much) and a little tighter then that too.. I have been careful to observe the direction arrows. The belts come apart at the joint after very little use. The latest one after about 5 minutes of very light sanding. The one before that while the machine was running but I wasn't actually sanding anything at that moment.
Two questions: What am I doing wrong?
Can I reglue the joints in the belts? What glue do I use?
Thanks in advance for any help you guys can give!
