Hi, there's this Bridgeport mill offered on eBay (auction
180414939748). It boasts an "air operated chuck". What is that and
how is it an advantage? I'm new to milling and found this auction
that happens to be very close by. (All the mills seem to come from
Ohio.) Any words of advice on what kind of buy this would be?
Thanks. --zeb

--Air operated chuck is damn handy if you're doing a batch of parts
one at a time. I've got a job where *each* part in a batch has to be clamped
16 different times; that takes up a huge chunk of time, just opening and
closing the vise. Air chuck is much faster.
--OTOH if it's not a vise but a real 'chuck' it's maybe the
pneumatic drawbar puller you see on some mills. That's another handy widget
if you're needing to change toolbits constantly..
