I picked up a large box of belts. They are new old stock. The belt

it handy, Gorilla duct tape went on and failed next.

Does anyone have a suggested tape or other fix so these belts are
usable?

If the ends overlap, you can use elmer's glue and fix by ironing
with a household iron. If they but up then you will need some kind
of cloth tape.

We use to make our own in school shop by cutting from a roll at a
diagonal so they would overlap by approx an inch. Then using a
grinding stone in a DeWalt radial arm saw we ground off the grid on
one end, put on the glue and ironed them from the back. Never had
one to come unglued. The stock roll was donated by a local plywood
maker.

GR:

These belts butt up with the tape overlapping that line.

We use some large, stationary Somaca belt sanders as well and it would
be interesting to see if some of this belt material could be cut for
use on smaller
machines. The notion that it might be possible to fabricate belts from
new roll
stock also poses possibilities; hopefully, some of them might deal
with saving
money.

As to your second paragraph, my head is a little hard. Does "grinding
off the
grid" mean you are grinding each end of the cut roll for a half lap
joint? What
kind of glue was successful for you?

Grid is my mistyping of grit. That was over 50 years ago but I believe
we only ground one end.
As I said, we used Elmer's glue. Yellow wood glue would probably work
the same.

If you're right 95% of the time, why
quibble about the remaining 3%?
