Bob,

I could make you an ER32 chuck to thread onto that... But the runout
might not be lathe quality... Maybe a few thousanths at worst. Probably
not terribly cheap either, but worth looking at if you are interested as
it's a no risk talk, eh?

Call and ask for Joe Jr. if interested.

I dunno. I think the taper inside the head meeting with the collet is how a
bit centers. The outside locknut and threads do not have to be as perfect.
May be compounded error there. Did I misunderstand how this stuff works?
Something screwed to the outside I think would not be as perfectly centered
as something clamped in the collet?
