Hello! I have a few belt sander belts that are in good condition, but the splice tape has failed. I have tried a few attempts at re-splicing, but they have failed. I tried using a piece of fiberglass matte as a splice glued with woodglue, but that ended up failing. I have to do a butt splice as the belts are not long enough to overlap.

Has anyone successfully done this? If so, what did you use?

Thanks! Dean

Klingspore used to have a service center in NC that I'd send them back to have that done. After the 4 the belt that they fixed, they had their rep come out and check the run-out on my machine.we made a few adjustments to the tracking and platten I never broke another belt, unless I tried taking to much material off per pass. I hope that this helps.

I tried to re-splice some sanding belts and never had any luck. Even contacted the factory for advice with no help. Some belts seem to last forever and some blow for no apparent reason. That tells me the factory don't really have it figured out either.

buy quality belts, haven't had a problem.

I agree with bob… Klingspore makes a bunch of great sanding products and the prices are very good for the quality. Give them a try and unless your sander has a problem you should be good to go.

I had several belts from Lowes that hung on the pegboard for a few years. Everyone of them broke almost immediately when installed. I think the adhesive breaks down due to environmental factors.

"buy quality belts, haven't had a problem. " Bob

care to elaborate?

it is definitely how their stored. I keep mine in a climate controlled environment and only buy a few at a time. I have tried EVERYTHING to fix them with no luck. the only type adhesive I haven't tried is something "ironed" on. I'll try that next.

When I was in Arizona, the heat destroys everything. I just cut them up and glued to different sanding board shapes. John

wonderbowman:

I have a shaft sander that is automated for tapering wooden arrow shafts. I had nothing but troubles with off the shelf "Lowe's/home depot type belts. A good friend of mine that worked in the Michigan auto industry told me to buy "3M" Belts, and go to the "J" weight backing. I did and haven't looked back. First off the 3M belts are not thicker at the splice like other brands are. The belt at the splice is void of grit, so you don't get a small portion of the belt doing most of the work and I could control the diameter of the shaft much easier. Granted I using a 1X42 belts for this process. They are not cheep but last much longer than brand X.

As far as I know, you can't reglue them, nor is there any tape that works. It's a factory thing. Which is a little hard to believe since about all they could be doing is adding some heat or pressure. Bladeforums is the obvious place for this kind of concern. Those guys run grinders like we shoot. But I didn't google much up there.

Last year I had my dad's whole stock of 1x30 belts blow, usually after less than a minute of running. Other than the one I am still using this year. Something wrong with that brand, and he had picked a lot of them up. For that size of machine I try to stick to the belts Lee Valley sells, as they are all standard good quality. But occasionally some other source or brand gets used.

In the past, hard core old school American supply companies don't buy or sell Depot or Lowes grade anything. Nowadays, products sold at chain hardware stores is built to consumer grade price point, and much of it made in China. The two supply house I buy specialty tools and supplies from nowadays do sell plenty of Chinese made widgets now, where thirty five years ago, they did not.

It seems odd that we can build bows that we glue fiberglass on to wood and they hold up to all the stresses during shooting, but only the factories producing sanding belts work.

I was thinking about trying a iron-on patch that one would use on jeans. I will have to give it a try!

Dean: The problem with most sanding belts happens at the splice. The spliced area is thicker than the rest of the belt, when you apply pressure while sanding, it causes the belt to heat up more at the splice, adhesives don't work well in heated conditions and fail. 3M solved that problem by removing the sanding grit at the splice. I have used close to 600 3M 1X42 belts and have never had a belt come apart.
