Oh and if enthdegree revisits I did it with a short K mount ext tube with the male end removed. I bonded the female end of a helicoid into the recess left by the removed kmount. Minimum length is just over 20mm but is still great for m42 bellows use.

Further to the bellows idea ... B.P.M. (in the UK) used to make a "Universal Bellows Unit" with, believe it or not, interchangeable mounts! Perfectly practical to have a K-mount at one end and an M42 mount at the other, or virtually any other combination. The unit was even supplied with a basic slide-holder to clip onto the bellows rail
