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.
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!
Lapped joints say old belts to me. Pretty much for the last five years or
so the belts I get are butted with something similar to fiber tape.
Could be what your problem is. Could also be that you're running them too
hot as they're passing over the platen and under the work.
Don't know what glue they use, but by the time mine have come apart (twice),
there's not much left of 'em anyway.

Probably running them backwards. Look for the arrow
to show the direction they should run. the glue joints
are made to work in one direction only on most belts.
I recently had to change belts on my 1" sandah and I
forgot that _most_ basic of rules. 2 brand new belts
snapped in under a minute. It was then that I saw the
arrow and blushed a quart. <sigh>
