Cut a mandrel to fit nicely into the bore. Slide the jug over the mandrel and use the live center to hold it tight to the mandrelView attachment 297376

I would not use any sort of plastic. It's significantly more prone to deflection. Bearing bronze would probably be my choice.

Plastic will work fine, I've used it, can't remember what it was called though. Ask the guy where you buy it what machines well, that's what I did. All my other mandrels are aluminum though.

Delrin maybe?

It was black. Can't remember, maybe, all I know is I was expecting it to be cheaper then ALU, and it wasn't.

All different colors of delrin. Could have also been UHMW.

Yes I think I remember the guy saying UHMW!

UHMW is pretty decent stuff. Some off roaders make skidplates out of it.

PE? This stuff is pretty tough and ridged even up past it crystallinity point. It doesn't melt due to the MW being so high. Macmaster-Carr has a great plastics selection guide on their site if you are looking for an appropriate polymer for a mandrel.

Sobering thought;

My daughters step-father missed a Stanley Cup playoff because he wouldn't pay $100 because it had already started...........

I had no answer.
