There is a product called PowerTwist belts that some folks in industrial maintenance may be familiar with.
They are made from a poly material, can be made to length, and be used normally as a standard belt would be.
We use them on belt drives at the plant under all sorts of conditions, and they last just as long as rubber belts. Similar to the auto store emergency belt, but the material is much better.
Definitely a good thing to have along. /forums/images/graemlins/thumb.gif
