I have not copied the transition from collets to tool holders or what ever you are referring to, but you're initial post stated
is in my humble understanding of English sayingpdcue said:"Not to beat a dead horse - but plastic collets are not as accurate as metal"
"plastic" has not the accuracy as metal. When they can be produced in a decent accuracy I don't see why they can't hold a pool cue in a chuck, where you obviously say that metal is the way to go.
Anyway, I give up, I surrender, I apologize for even expressing my experience on this :bow-down:
Use you're metal collets and I?ll stick to my custom "plastics" one. It's just two different version of the same thing.
