I'm doing most of my work with an 8" 4 jaw unless it fits my collets. The 4 jaw has
serations in the jaw that makes it hard to use for small things. I wish the jaws were
smooth.

Greetings Wes,
I have been turning parts for about 35 years. On all sorts of
equipment. I use almost exclusively three jaw chucks that I have
modified to be adjustable. Using good chucks they repeat well and
adjust MUCH faster than a 4 jaw. I know, I know, folks say that when
you learn how to use a 4 jaw properly it's just as fast as an
adjustable chuck. Not for me or anyone I know. For work that has to be
adjusted less than .020" an adjustable chuck is the way to go. And I'd
spend the money getting a good plain back chuck and making it
adjustable rather than spending the exorbitant money they charge for
them. Jest my 2 cents.
