It is not delrin, it is UHMW Polypropyline (sp?). It is very soft, incredibly easy to machine, doesnt really melt at all, but I wouldnt cut it with a dremel. Drill press is great for accuracy.
BTW, I finished my GPU WB tonite, I am leak testing now. My camera wasnt charged, so I didnt get any pics of construction, but I'll get some of the finished product sometime tomorrow. Nite Nite
