Hi Jesse,

Yes, I used your Signet ring as a guide to make my own version for milling, so Thanks goes to you.
As part of my tests for the rotary, I wanted to see how a Signet style ring would actually come out.
Here's my Signet ring version that I used for the test.

I allow a 2mm margin on each side, this guards against the cutters coming into contact with the cones.
I figure the wax is cheaper than the cutters, so it's a cheap form of insurance against cutter damage.

Thanks for the links, that's something I'll have to try out.

Here's a photo of the rotary with the Cone Clamps holding a wax.

regards Colin
