Scotch brite belts
I ran a search on this as I thought there was thread but nothing came up, Just wondering if any one has successfully rejoined broken (at the join) butt jointed Scotch Brite linishing belts
I have had 2 let go in as many days not new but plenty of life left in them at $15 each it would be worth fixing them

Hi China, Guys,
They are not going to be easy to join at all. Initially I would used a strip of gaffer tape on the back, now you need to find a solvent, a bit like PVC pipe cement. Fold it back and paint the edge with solvent and keep your fingers crossed.
They do dissolve in some solvents, though I must admit I don't know what. I can tell you that I've had some Scotch Brite material disintegrate when in contact with a degreaser spray.Best Regards:
Baron J.

I bought some sanding belts that were old but the price was too good. I have had a few "let go" so I did a search and found some joining tape on Timbecon's site. Its a Fast Cap product. As yet I have not used it but I did use some of their other tape to give me a white edge on some particle board and it worked just fine. My thinking is that the Fast Cap brand has some good stuff
Just do it!
Kind regards Rod

Scotchbrite belts.
Hello China.
The belts are joined with mylar tape and polyestereurathane adhesive. The glue is mixed with red desmodera accelerator and then heated under a press. This join is subject to moisture in the air and after a year or two will fail. The backing, or scrim will make it hard to join. Fiberglass tape has the strength but to get it to adhere to the scrim?
regards
BC

Thanks for the replies, sounds like it will be a hit and miss operation, may not not be worth the trouble.

Tape it up on the back with a fibre reinforced tape and squirt a bit of cyanacrolate into the ends. If it doesn’t work you haven’t really lost anything other than a few drops of super glue and a bit of tape.

I've had the same issue several times. It seems related to time, not use....
I have considered several time to tape the back and then sew the ends together with some thick cotton or this steel braid or cable....
I hqv3n't done it yet, but any thoughts?Cheers, Joe

If you are thinking of sewing, try dental floss.
I made this strop belt about 13 years ago - don't use it much but its still together after all that time.
All the sewn edges are cut on a slope so thet don't catch anywhere provided the best rotates in teh same direction.
