I’ve never had issues with belts on my machines in the past. I bought a ShopFox Mini Lathe about a month ago and have been stumped by issues wth the motor belt. The first belt wore/shredded after only and few hours work. I assumed I didn’t change it right when changing speeds and it disfigured due to misalignment. Got the same belt new. It appears to be wearing on the threads once again. ShopFox is a lower end lathe, even for mini standards. Knew that going in. I’m wondering if it’s a design flaw or user error. Any thoughts? The actual wheels do not appear to be rough in spots I can see.

If the pulleys are in good shape…it sounds like it may be pulley alignment. No way to know for sure though. One belt could be a bad belt…but it is unlikely you would get two different bad belts in a row. Is there a way to post a picture of the belt and pulleys ?

What width belt is it? A, B, or some new style design.

My Grizzly also shredded the original belt within a few hours of use. I had Grizzly send me some replacement belts and the second belt has been on there for about 20 hours of use and shows no wear so I assume the factory belts were crap.

Try a different belt MFG?

It could also be a tension issue coupled with the pulleys being out of alignment.

Can’t add anything except to say that I have the same belts that came with my lathe 14 years ago and I have used it a lot. So either they are very poor belts or there is something else drastically wrong.

Have you noticed stalling while turning something large.

That’s caused by slippage, so check the belt tension.

Thanks for the tips. The second belt, identical to the first, seems to be holding up. I’ve been more careful to be sure it is properly seated in the threads and such to eliminate as many variables as possible. Not sure what type of belt it is as far as Dick’s question. It isn’t a solid belt like on my drill press. It has several plys that match the recesses on the wheels it self. The plys are what shredded. Once that happen it acted more like a screw thread and worked its way in one direction until coming off. The tension seems to be as the manufacturer intended. That could be good or bad, can’t say. It does seem to tension properly after the change and doesn’t appear to change under load. Time will tell – gotta whip out some more chisel handles so I’ll stop there.

An A-belt is 1/2”, & the B-belt is 5/8” wide, but I see your belt is in a specialty category.
