Belt sander

(1/2) > >>

DC:
I have a cheapey Canadian Tire/ Harbour Freight/ Whatever 4x36 belt sander. Works great but the belt has started drifting. It goes over to one side and with a minor adjustment it drifts right over to the other side. Can't make it happy. It's worse if I load it down a bit like doing Boo backings. It's been around for 4-5 years. It's just started doing this. I put a little pitch on the drive roller and that helped for a few days. Probably wear but where? See what I did there he he ;D ;D

Pat B:
Have you tried a new belt? Mine drifts when the belt get old and loose. It's a 6x48 Grizzly.

DC:
I've read that on the internet and I can't for the life of me figure out how a loose belt can make the sanding belt drift. I'll believe you but I'd sure like an explanation. I'll have to go look for one.

Pappy:
I had one and the bushing in the front roller was worn, it was hard to keep it adjusted for the belt not to drift, especially when you put a load on it.
The better ones have bearings but this cheaper one I had just had brass bushings in the rollers. :)

DC:
Mine has a bearing in the front and it seemed OK but the shaft seemed to have some movement on the side without the adjuster. I cleaned the rollers and ran over the drive roller with some 36 grit because it looked a little shiny. I try it a little more today but it seemed like if I loaded the adjuster side(left) it runs true but if I load the right side the belt moves right.
