Default sanding belts coming apart at the joint.

Greetings!
I have a bunch of never used but old sanding belts that are failing. Will find some use for the ones that already failed but interested in possibly reinforcing the ones that are still in one piece. Any suggestions welcomed.

thanks

I would be interested to see if you find anything. I did not.

I doubt if there is any practical way to reinforce them. They are probably brittle and might fly apart anyway. I repurposed some old ones I had as block sanders, I. E. Glued to wooden blocks. That's about all I figured they were still good for.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

I have a bunch of these too...figured that they're only going to be good for sanding blocks as Chuck said.

the failing is because of age... they have a shelf life...
if you reinforce them it will cause a high spot in the belt that will thump the sander and leave a mark on your work...
many try to repair them w/ mediocre results but in the long run the belts get re-purposed for the sandpaper and new ones are purchased....

The tape used to splice belts is a very specialized adhesive that is shipped and stored in dry ice. The application process then requires the belt to cure for 24 hours. An off the shelf adhesive generally does not have the strength with the shear pressure on the seam.

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

Inefficient, but i pretty much only buy one at a time because the glue does dry out. I've got about a lifetime supply of old 100, 150 and 220 grits that came with my C-man 6 x 48 that I've made sanding blocks, etc like everyone else. Just now i'm wondering if i could cut a few of them into 1/4 sheet size to try in my palm sander. Cloth back should hold up pretty well?? Any reason not to try it??

just pre-roll/fold the edge so the paper will fit and clamp up easier...

By coincidence, this article on making a sanding block to use old sanding belts was posted recently.

https://atelierdubricoleur.wordpress.com/tools-index/

Many years ago, I purchased a box of "offcuts" from their belt manufacturing process from Klingspoor. I've used them on my PC palm sander with no problem, a little tough to install in the coarser grits but doable if you preform the edges that go under the clamps as Stick recommends.

That's what I do. I'm not one for throwing away something that I can still use somehow.

I have 2 belt sanders. When the belts get too brittle for use on them, then I use them with sanding blocks. I have two 1/4 sheet sanding blocks (with clamps on each end) that work perfect for these.

Hi, hilcntry...don't know what your experiences are so ignore this if you've already considered belt direction.

I couldn't pass up a deal on a case of 'em many, many years ago and still using them on my Bosch. Got one box of three left...gonna miss 'em...
