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.
I would have tried rolling them on two pieces of perspex but as i made them for a customer i can't really get them all scratched can i.
They are on a thick towel as i was using a glass table and didn't want to explain to her indoors about any accidents. :whistling:

Maybe when parting off you held the piece in a revolving chuck in the tailstock. That would still leave a mark, so take that chuck and put it on the spindle and machine the other side? It should still be on center so that could work ... probably something a bit more ingenious though
Possible some sort of turning between centers was used ('save material').
I guess the question to ask is was it all machined in one operation or not?
