Info on Masterchuck

Is it even made any more? I own one, but the only part I use is the pin chuck.

If it's the one I own, it was a temperamental S.O.B. that had to be nursed and cursed thoroughly to do its job properly. It made a better turner out of me, though. If you can turn and not lose your work on that beast, you can do anything.

You say inserts. Are you talking about the jaws themselves, the retaining ring, or what we are now used to calling inserts - the part that threads to your lathe? If the first, you pay shipping, I'll deliver. If the last, you'll have to go with an adapter. Packard's got 'em, as do other places.
