In this video I discuss both older and new Cole jaws, different Nova chucks and how to use my custom grippers in various situations. Also some turning video to prove it all works.
This video was very helpful in an unexpected way: I built a longworth chuck, but it was about 1.5mm off-center. I realized from your video that I could tighten the grippers selectively to squash down and compensate.
I was about to give up on my PSI Chineese made jaw chucks, as the rubber grippers left marks on the bowls, and then bent, throwing the bowl onto the ground. The new grippers came yesterday. They fit the PSI jaws perfectly, and held my bowl securely. Thanks for this great addition!
Dennis, my understanding is the longer screws to adapt your original jaws to the Cole Jaws was to give versatility to turning, enabling you to turn your bowls around with out changing chucks, at least that was my take on it. Enjoy all your videos and also the tools that you sent me. Thank you.
Yes, I just got a set of these and read the manual. Using additional jaws is optional. If you want to do it, use the longer screws that came with the cole jaws. If not, use the short screws that came with the chuck.
suggestion... make new wooden spacers wide enough to bore a hole to fit around the grippers. glue in some wooden dowel pins and align them using the unused holes. this would space the bowl out properly and prevent the spacer pads from being thrown loose during turning
I had to buy some of these grippers off of your eBay store. Those little button grippers do exactly what you say - they deform inconsistently and cause my bowls to be not-concentric, as well as always being at risk of my work flying off.
Why not put a large washer between the bottom of the rubber and the aluminum flange. That is larger than the flange diameter. That way you can have the lip of the bowl supported against the Cole jaws, not have to have wood piece as stand offs and not mar the piece with the flange.
