I had a good look at what you did with the m39 adapter and that makes sense. Did you use a c-M39 adapter to glue to each lens? Something that looks like this below?hmmm, a C-mount adapter on its own has some thickness and that will leave you with very little room to work with...
Is there a reason not to start with a M39 adapter (thread mount common of so many old lenses)?
In my case I had to do very little cutting/shaving to create the room for the diaphragm, and then some JB-Weld.
Unless, if I understand you correctly, you want an interchangeable adapter where you can swap and mount all the Pentax-110 lenses?
In that case you have indeed 7.75mm to play with
If you have time can you let me know the outside diameter of the iris that you bought or the inside measurement for the m39-m4/3 adapter and then I can order everything at once.
