Today's project was making a couple of drive rings that will fit SK40 DIN69871 tooling to the spindle of my 1964 Deckel FP2. I only need one, but figured it was not much more work to make two.
The rings are thinner (3.2mm) than the normal drive rings used with SK40 S20x2 tooling, so I put the drive dogs directly across from each other, rather than offset by 90 degrees. The drive dogs on the spindle side are symmetric (left hand side below); the ones on the tool side are asymmetric (different inner radii, right hand side below).

Clik here to view.
These are made of carbon steel (C45). I'm probably going to harden them, is that the right thing to do?
Cheers,
Bruce
