I am going back to a problem I tried to solve and was ridiculed by Evan :D if I remember correctly (IFORIVE HIM:D). Anyway I digress I bought a load of new sanding belts they turned out to be too big for my sander. Widthwise they were great but alas too long.I shortened the belts and reglued them thinking I was smart with kidskin and gorilla glue.This immediately broke during a few seconds of trial. After many attempts I threw it in the corner in disgust and thought as usual my Pal Evan was right in his assumption it was not worthwhile. Anyway I looked again recently and was pleasently surprised to fing that it was actually the kidskin that had failed not the glue joint.I have a good pile of these and want to try at least once again.I wonder if you guys could suggest something else ?The manufacturers put a small piece of plastic like a fraction of a credit card in the gap and somehow glue that on .I realise I will need something bigger longer and better.any ideas something which is flexibile and tough.Alistair

How about gluing them then backing up the joint with a high strength fibre reinforced tape?, thats how the butt joined belts i use on my bench linisher are done, granted i dont know where you might find the tape tho.

Sanding belts are Evil Alistair. Give them to your psychologist.

For the 36 grit you might try pop rivets. Not sure if they make them small enough to use on your 500 grit belt ?

There was a thread about gluing leather belts and someone said they use a celaphane strip with acetone to glue them. How about asking a belt maker to tell you or have them shorten them for you.

I tried the 3M plastic trim adhesive (a clear contact cement) amd it seems to be working. Just used some thin ?? fabric. Made the fabric patch about 5/8" wide, masked off that 5/16" on each end of the belt, coated the splice area on the belt and SATURATED the cloth patch. Covered with waxed paper and a board and clamped for a while.

Like the sound of the carbon fiber, just none in the scrap box.

I think the reinforced tape coud be glass fiber reinforced and the adhesive high temp thermal, how about woven fiber glass matting & a polyeurethane adhesive?

I'm with Nick. Fine fibreglass fabric - probably "6 -ounce" (USA designation, UK users may get different results, the 50-cycle AC don'cha know), plus a polyurethane adhesive like Gorilla Glue. Leave a nice wide band, saturate it well with the glue, and clamp it between two pieces of release paper (or waxed butcher's paper, if that's all you can get). Give it 24 hours to cure, clean up the mess (there will be one), and try it out. And then tell us how it worked out. Good luck!!!

One thing I haven't seen mentioned - the overlaps, if there are any, have to be oriented so they slide OVER the workpiece, not butt into it, which will tear the joint apart in no time.
