Tom’s Techniques knurler

[C-Bag]

Thanks Bill. For some reason in my one track mind I thought the relief would have to go the whole width, but then the holder wouldn’t be supported!? But your solution solves all that nicely. I think I got a woodruff key cutter in the assorted stuff I got with the old RF30 that I’ve never used. Would be a good excuse to dig it out and see if is the right size.
