Now this is why I come here. I never would have imagined such a thing.
Dumb question time: Four jaw chuck?

[Mark Hix]

Not dumb, I was sitting here thinking the same thing? do you take two off and leave them off or was that just for the alignment marks?

The captured ring was turned on the off center axis and is captured not only on the stem but is also captured between the transition points of the two axes.

Hi Jason,
You must be a swifty, 'cause that's nifty!
Nice work, too cool...
Ya, I guess you did want to do something different!?!
Mission accomplished.

The ring is captured between two axes? whew
Thanks for sharing the explanation pics, too.
tricky stuff, good luck with it,
Walt

Not very profound, but when I have done similar off-center items I have just left an extra inch on the blank at the base and used a thin Sorby fluted parting tool to undercut the base. If the tool is sharp, and the wood compliant, you can even leave a clean decorative raised circle. Cut the nub off with a hand saw at 1/4 inch or so and then carefully sand off the lathe, leaving a neat button where the nub is. Might even be able to fit a bit of sharpened Formica in there for some burn marks, or blunt to burnish the edge. I also do this for simple boxes to avoid re-chucking. All this is not perfect, but often very acceptable. FWIW. Jerry

Mickey/Mark. It's a 4 jaw chuck with the #2 and #4 jaws removed. This allows for the side to side movement needed for the 2nd axis.

Thanks for the extra pictures. I believe I am starting to understand. So much that would be fun to do and so little time. I saw the finished dimension but how large a blank do you start with?

[Jason Clark2]

Steve, the blank was Mesquite and started out at 3 1/4" X 3 1/4" X 10".
