Breaking Sanding belts

Not sure how well it works, but did find this link.

If they have it down under, then we should have it up over.

I also read that the seam tapes are vulcanized in place by manufactures meaning ultra high, short term, pinpoint heat to join the belts. I'm sure some sort of prep is also required.


PS, read the very last post in this thread.

That is what I suspected as well. Special sauce.

I tried gorilla glue on a 6x48" shopsmith belt. Glued, clamped, let set for 2 days. It left a raised bump that was annoying but it kept the belt in service for about 5 minutes before failure. Tried it again but it only lasted a minute. Gave up after that.

Loring,
The same thnk happened to me. I unearthed a box full of belts (Craftsman) I never knew I had. The belts must have been 10-15 years old. After the first 4 broke, I just tossed the entire box and got new ones (Norton). It just didn't pay to play around with the old ones, even if I may have found some that still held together.

These belts are butted and taped, not overlapped and glued.

Sounds like it is time to make that hand sander tool that uses old sanding belts.

Seriously though, at work I've seen one in the shop, but not looked closely at it since our projects seldom involve sanding. I think it has a spring that tensions the belt around both rollers. Since a manual sanding pad would just hold a belt and not employ any belt rotation, you could do something like staple the ends together, or just make a clamping-style sander pad that takes the broken belts as-is.

that's the secondary plan...
cut some 2x4 blocks about 5" long and cut the belts to about 7" long and wrap around the 2x4 and staple to the ends to make some Quick and dirty sanding blocks. I should be able to make...30 or 40 of them

Loring, have you tried repairing them with filament tape, probably stronger than duct tape?
Good luck,

The tape doesn't tear, the adhesive pulls off, first.
