I have a chuck from CSU called the Apprentice Chuck. I was trying to find Cole Jaws to fit it but they don't make them. Has anyone out there made your own cole jaws. If so, any advise would be appreciated.

this may be a little different than what you were looking for....but it is one way to do it.
and you can find the rubber baby buggy bumpers at woodcraft, also.

Hi...
I got your email and then I started writing up a whole description of my construction process and thought the rest of the community might like to know, too.
Here is how I built the jaws that are shown here:
http://www.penturners.org/forum/topic.asp?TOPIC_ID=19225&whichpage=1#218161
The following is what I'd started to put in my email reply:
Basically all I did was took a 9 3/4" square of 1/2 baltic birch ply (solid, no voids) that I lopped the corners off and drilled holes to fit on the chuck. I mounted the whole thing TO the chuck without jaws in one solid piece I used the screws that would normally hold the jaws. Do this with the jaws fully closed. Then I turned it round. I took the parting tool and made a few grooves in the face to create a few concentric rings - makes keeping things centered easier. They should be close enough together that the travel of the jaws can "overlap", or better said, they shouldn't be further apart than your chuck's jaw travel.
Then once it was round, I marked where the cuts should be to make it into 4 pie pieces that could screw to the jaws. I tried to shoot for 90 degrees as best I could, but didn't go to great lengths. Once I had a nice X marked, the full size of the disc, I cut the thing into 4 pieces freehand on my bandsaw. Keep on the line as best as possible, but being straight really isn't crucial.
Once I had these pieces cut, I drilled a pair of teeny pilot holes at one of the lines made by my parting tool. In this case, I just picked a ring that would fit the current bowl I had in mind that day. I have a 1/4" thick anti fattigue mat that I cut into some 1/2x1/2 squares to use as my jaw pads. I suppose some more sophisticated materials could be used, but these served my purpose just fine. I screwed them to the pie pieces using the pilot holes. I used some #6 3/4" panhead screws, but 1/2" would do fine, too. The real trick is to get enough of the foam between the screw and the rim of your bowl.
That pretty much covers my construction technique. I hope that helps

I'm about 95% certain that the Apprentice chuck from CSU is the same as the Barracuda2 from Penn State Industries. Penn State markets a set of 8" flat jaws for the Barracuda2 that I believe will fit the Apprentice:
