I looked around and couldn't find anything about the type of adhesive to use on sanding belt joints. I've had a couple of belts seperate at the joints, probably because of too much heat . Is there an adhesive made for fixing that joint? Thanks
 
That's what I have been doing, most aren't that expensive. I've got some though that $10.00 apiece and would like to get some use out of them. They must adhere them somehow when they make them, just trying to find out what they use.
 
It's impractical & expensive

The original adhesive needs refrigeration storage, heat -pressure to cure & special handling.
 
If I were going to try something, I might try loctitie 330 Depend. I would not be expecting good results. I would be questioning belt quality.
 
As some else here has reported, the adhesive is very expensive, must be kept refrigerated til use and has a very short shelf life (24 hrs or less) once opened. Even if you as an indiviual could buy it, it would be completely impractical. You need to be glueing up hundreds if not thousands of belts at a time to use it up before the product expires. I'm guessing here but I wouldn't be surprized if it had some curing procedures that aren't commonly found in most shops home, private or commercial i.e. uv treatment.
 
Yeah, I'd say that a much better use of your time would be in trying to convince your belt suppliers' customer service to replace those belts.
 
I guess nothing is simple. It doesn't sound like the original process and product is not something for casual repairs. It would be nice if the original joint adhesive would at least last long enough to wear out the abrasive. Anyone have a supplier of a quality belt that goes into the 1000-1500 grit range?
 
If you're using good quality belts I would start looking really close at your grinder to see if something is causing the belts to break. Would too much tension do that? Is there a sharp edge on the platen rubbing on the belts? Would pushing down on the belt too hard and too long while grinding do that?

Hope you solve the mystery.

Instead of throwing them out can't you cut them into smaller pieces and use them for hand sanding? That is, if you do any hand sanding at all.
 
If you have old belts they will come apart at the seams. Heat might tear one or two up, but if you're going through them often enough to worry about cost, then I would guess it's age related. You can look for someone who will re-splice the expensive belts for you. If you have enough, you can probably get them done for about a buck a piece. Tim Britton pointed me to Pete McKinney in Hickory North Carolina for this service several years ago, I don't know if he still operates.
