Once you have the old bayonet mount off what do you actually have to lathe?
From your photo it looks like you have removed material from the outer ring of the M42 adapter so it will center in that ring around the rear lens element. Are you making the M42 adapter thinner for infinity focus? Is this where the lathe comes into play?
Thanks for all the advice and photos by the way...
Here is a photo of the old mount and the M42 adapter. It seems like the diameter of the opening on the M42 adapter is ever so slightly wider than the Minolta mount. Is it possible to mount the four screws through the factory holes on the back of the aperture ring and have enough material for the news screw holes on the hole opening edge of the M42 ring?
