Hmm, so did you machine them all in one operation? Or are you not disclosing how :naughty: I saw the other thread about it here a while ago.

My approach would be to turn the pointy bit and then basically part off the lightly curved face first roughing a relief down to maybe 10mm dia and then finishing the face and parting off the final 10mm in one go - if you get the tool shape right it should work ok.

Anywhere near? :-)

I thought it might be that, but there's no mark at all at the center of the lightly curved face.

Maybe, getting warm :lol:

It will make it interesting for those that watch but do not participate in the threads to see how various minds work.

The piece is 48mm diameter and will not go through the headstock of my lathe.

So material cost has to be considered, it is not a secret in how i did it but just a bit of fun not to give the game away too easily. But i will let on if anyone gets close to my method.
