I agree with Ron - that definitely sounds like Delrin (generic name
Acetal)

Stuff is considered by machinists to be the nicest material they've
ever used - can be finished to a high gloss finish, feels like marble
to the touch but machines like butter.

I sell small offcuts of it in my ebay stopre;

Have a look and see if that's what you want to be using.


I've seen some other guys receommending phenolic as well - be careful
with this stuff. You should be wearing a mask with the canister
respirator attacked if you're going to do any machining on plenolic -
it has very fine particles and you do NOT want to be inhaling them.
