Darren:
The chip should not present any problems with mounting :thumbup:

rvt:
Ah, thanks! I didn't look at the picture carefully enough. I now see that a three jaw chuck would fit in fine :)

Darren:
I presume this needs to be machined very true/square, that would suggest a dedicated holder or at least soft jaws on a three jaw chuck.

I would consider one of these, esp if you had a few to do. For that matter if my turret lathe was set up I suppose many could be done in an hour.

I have done a few little jobs like that, adapting old lenses, telescope, etc to my camera. (No chips though, I am a "Pentaxian" :med:)

The method I used was to buy to an old camera and adapt the camera body flange to fit a piece I could hold in the lathe then when I need to machine an adapter in any way it is firmly held by the camera body flange and is easy to remove.

I found when trying to hold in the 3 jaw that there is a fine line between too little force which causes slippage and severe cosmetic damage and too much force which produced a tri-cornered adapter!

Another thing you could use would be an unwanted macro tube which you could maybe fill with resin to get something solid the chuck would not distort.

Darren:
Some nice ideas there John, :clap:
