Ok, now I understand.Now I don't get it.
The bayonet part of the 110 lens is smaller than the opening of the C/CS adapter.
No friction around. That is where the glue comes into play.
I'm filing down the internally threaded end of one of the C/CS adapters to get the same focal flange as a proper C-mount lens (17.526 mm) on the Pentax-110 lens in combination with the unmodified C/CS adapter. I'm not filing down the externally threaded end. (The end you'll screw into the C to M4/3 adapter)
Then you'll have infinity focus when mounted in a C to M4/3 adapter. Or indeed in any camera with C-mount adapters available. I'm using my lenses in a Pentax Q, for instance.
