Best
way to keep a belt drive from slipping is to use a pulley with teeth. But if
you need a custom belt, mold the teeth out of epoxy. And be sure to use mold
release on the belt.
The
most critical part of doing this is making the pulley the right size to make
the belt ends come together without extra space. So I do not know if it can be
done on a rim pulley.
Spoked
V-belt pulleys can be found very easy in many diameters, and its a
cheap experiment. Epoxy doesn't like metal much, but If the metal
under the teeth was scored with grooves by some kind of engraving
tool, like a Dremel to give the epoxy more "bite", or make
sure the epoxy goes into holes, it will last longer. Maybe even fiberglass cloth may help.
If
you're going to bolt tabs on the rim to hold it in place, do that
first.
