Lyle, I get mine from Mcmaster Carr. Delrin is the trade name for it, but you will also see it as acetal copolymer, probly listed both ways. By tradename,Delrin 100 is what you want, its the most inexpensive, just plain delrin, no fillers or anything.
I use quite a bit of it for predator calls, if you need any help with anything just holler.
