I want to make centers to use for finishing pen barrels. Obviously, I want them to be something finish doesn't' stick to, including CA. When I went shopping, there were a plethora of choices, HDPE, Nylon, Delrin and on and on. What's best?
As I understand it Delrin is a trade name but it is an acetal plastic. I am no chemist but I dont think CA sticks well to many high density plastics. The bushings I made do get CA on them but only after they have been scratched up. A quick touch up on the lathe and they are good as new. No stcking problems. I just used this rod because it came in a dowel and easier to make a bushing with.
