Another possibility is that you use neither Cole jaws nor a Longworth chuck.

Since both drive the work from the rim, they are useful only for bowls.
Neither is of much help with hollow forms, natural edged bowls, and
bowls with semi-closed shapes.On the other hand, a home made jam chuck
works with all of the above. It does mean that you need to hold the
work with the tailstock so that there is a little hand finishing in the
middle of the bottom. Later on you can set up a vacuum system, use your
jam chuck as a vacuum chuck, and can finish pieces completely on the
machine. I have a couple of bucks in my jam/vacuum chuck.

Even then, you are sometimes going to have to hand finish -- I've
recently turned a hollow form but couldn't vacuum chuck it because of
bark inclusions.

Super Nova chucks, maybe the Cole Jaw Set CM021.

Since the new lathe, Jet 1014 only swings 10",
is this jaw set too large in diameter?

I think there is also a smaller cole jaw set,
but can't seem to "Google" out the collapsed
(retracted) diameter of this set either.

If it is handy, could someone please give me
a measurement or two?

Thanks in advance,

Why not consider alternatives such as the Longworth chuck which you can make
yourself for a few [pennies / cents]? Have a look at, for example,http://www.morewoodturning.net/lwc-wtm.htmor Google for alternatives.

Hello Chief Lynn,

As Ian says, the Longworth Chuck is an excellent alternative and you
don't have to change chuck jaws to use it. For the full list of
information on the Longworth chuck at my website to to http://
www.morewoodturning.net/chuck.htm. One advantage of using the
Longworth chuck is that you can make it to a size to fit your lathe.
However, I believe the Small Cole Jaws for the Nova Chuck will work on
your 10 inch swing lathe.
