2x72 grinder discussion

Main issue is tracking. It has tendency to work fine multiple times and then just throws the belt off.

Heck I can do multiple things for like 20 min of use and then suddenly it throws the belt off!

Belt tension will do this, as well as the tracking adjustment wheel not being in the same plane as the drive wheel

I believe the belts stretch slightly as they are used, I don't see any way to take that up automatically in your grinder, that could be cause for it to throw the belt

And I could be wrong but it looks like the tension wheel is not in the same plane...often the thickness of the adjuster mechanism is forgotten about and the adjuster wheel ends up further out than the drive wheel, I think that may be part of why your tracking wheel is tipped down so far from level

Ive experienced both problems, the second I was able to move the tracking wheel closer to the same plane as the other wheels. That fixed belt throwing 95% of the time

Also, a slight convexity on the wheels can help keep the belt centered and make it harder to throw

You can try it by putting a few wraps of tape on it to center the belt better.
