Threaded 2.35mm mandrels

I don't quite follow that Mark. If it's sanding drums you are referring to, then the cavity in mine is more like 3+ mm in diameter and require a tapered screw mandrel.

These are the polishing drums I wanted the mandrels for, Dennis:

The basic design for the type of mandrels I needed can be see at the bottom of the picture, though the ones I showed in the first link in my opening post have a longer threaded section on them and are better for the job really.

Ah I see now. You gave two links in your first post, but I only looked at the second one. So I was on a false trail from the start. Sorry about adding to the confusion. Dennis.
