I have a KISS wind generator wind generator that develops vibration at certain wind speeds. The problem is that there's a PVC fitting that goes over a 2" stainless schedule 40 support pipe that is loose fitting. I want to machine one with a sleeve bearing on a lathe and make it out of plastic. However, I really don't have any experience machining plastic, I've been looking at
Nylon Acetal UHMW LDPE HDPE
Comments on the machining qualities, UV resistance, and overall strength of these would be greatly appreciated.
