scroll chuck jaws - anyone made 'em?

[Hopefuldave]

That'd be really handy, Tony, I think I have the geometry worked out from first principles but confirmation or contradiction would be great! Assuming I've worked it out correctly, the jig should be pretty simple but would need fairly accurate construction - a couple of critical dimensions that probably need to be within a thou" or so plus a good fit to the jaw blank and some reference points to measure from should do it. If it comes out the way I think it will, it should work on a rotary table on a vertical mill or milling slide on a lathe, or at a pinch bolted to a faceplate on the lathe... If it comes out right!
