Wooden Cole chucks!

[Mrs Blackie]

I really want to make a wooden cole chuck, I have been looking up google for a bit of info but having a blonde moment again, I am just wondering if any one has a plan for them and if possible to forward it as so I can print it out and work looking at it at least. Old age must be catching up because by the time Ive gone back to the workshop, I've forgotten what I read :B please please pretty please somebody save me:U its not just a matter of reading it and doing it I could print out the whole thing but I think I'd do better if I had a picture of it or plan I dont know how big the holes have to be oh and do I use rubber stoppers? the more I write here the dummer I'm feeling please don't put me in the dummies corner hehehe... I'm still on my L's:;
Cheers!

Think you mean Cole Jaws (http://www.google.com.au/search?tbm=isch&hl=en&source=hp&biw=1680&bih=871&q=cole+jaws&gbv=2&oq=cole+jaws&aq=f&aqi=&aql=&gs_sm=e&gs_upl=1658l3712l0l4743l9l9l0l1l0l0l269l1247l3.2.3l8l0) how big are you after?

Edited as I read you were having a Blonde moment could you mean Jam Chuck (http://www.google.com.au/search?tbm=isch&hl=en&source=hp&biw=1680&bih=871&q=Jam+Chuck&gbv=2&oq=Jam+Chuck&aq=f&aqi=g1&aql=&gs_sm=e&gs_upl=3395l6297l0l7960l9l8l0l2l2l0l314l1379l0.1.4.1l6l0)

I don't know where Google might have taken you, maybe you have already seen this.

A pretty good description of how to make the jaws and page 2 has the buttons to go with the jaws. Some good pictures to help.


Good luck!

Mrs B. Suggest you google "Longworth Chuck". It will do the same job as Cole Jaws, plus you can make it yourself.

What they said. But a simple predecessor is easiest before you jump into fully adjustable.

Place a plywood disk on a faceplate. Turn a groove to mate with the bowl rim. Set the bowl rim into the groove, and wrap tape from back of the disk, across the side near the bottom, and back to the back of the disk. Fold a few mm flap of the tape onto itself for ease of removal. Do this at least 3 times, 4 easiest.

Turn the bottom and you're done.

Reuse the disk as available for different rim diameters, and when no longer adaptable discard it and use a new disk.

Even with Cole jaws and Longworth the tape is good insurance.

Cheers,
Joe

Mrs. Blackie,

I prefer Joe Greiner's system as it is very accurate and simple.

I bought a set of Cole jaws for my Oneway chuck used, but in like new condition. I found when used the bottom of the bowl oscillated a bit. The buttons / knobs don't all squish the same, so the bowl doesn't exactly center..

If one only has one chuck body and has to put on the Cole jaws, then put the buttons in the right place to hold the bowl, cutting a groove in a piece of ply or medium density fiberboard is quicker and more accurate.

"Joe Greiner's system"? Huh?

To give proper credit, a more detailed description is in "Lathes and Turning Techniques, The Best of Fine Woodworking," ISBN 1-56158-021-X, page 111, by Betty Scarpino. At the time (ca 1991), the usual practice was to simply sand bowl bottoms flat. This mounting technique, and its successors, enables more professional treatment, especially provision of a foot ring for better stability. Also allows extra turned features such as concentric ring grooves.

Cheers,
Joe

Correction: The procedure as outlined above by Joe Greiner.
