Sorry I forget how high prices are in Europe with VAT etc. I bought a used Pentax T-ring adapter with 2" very short adapter that would fit in the end of the 2" focuser and found that it wouldn't come to focus. That is when I bought the used 50mm in length 2" adapter that was not threaded at the end for the Pentax T-ring adapter only, it looks like this that I linked to before.

As you see this is really just a 2 " extender and the short adapter I have was made for the set screw type set up not the brass non-marring type, I use electrical tape just in case and it has worked.
You have to have a extender of about 40mm to 50mm to reach focus with a camera. Unless other cameras are different . My camera is the Pentax K100D Super.
I am not sure what you are saying about machining the end adapter but it would be short and would not come to focus with camera.
