I need to make a non-marring roller for my bead roller and am considering using delrin. Does this application sound appropriate to this material. If so, where's a good place to get a cylindrical chunk of the stuff. The piece I need is ~2" x 1 3/4" and I'll want to buy 3 or 4, so a piece 2" x 10" will be just about right.
Any other suggestions for material or a resilient coating for the existing rollers would be appreciated. I tried a doubled up piece of inner-tube and it worked fine, but the edges of the metal cut into it after a few passes.
