I need a connector for a combined physical mounting and low-pressure pneumatic application.
The overall dimensions of the connector with the male and female parts mated needs to be less than 3/8" diameter by 1-1/4" in length. The male part needs to be 1/4" in diameter, ideally 1/2" long. There will be a 9/64" hole drilled through the connector to pass low-pressure air. The end of the male part needs to mate precisely with the bottom of the female part to prevent air leakage. I need to insert the connector and twist it to lock, and it has to lock at exactly the same place (rotationally) every time. The details of the locking mechanism aren't too important -- a bayonet mechanism with a stud is ideal.
I have no idea how to make such a thing. I have a lathe, mill, the usual power/hand tools.
Has anyone made a twist-lock connector of any kind? The bayonet style apparently has a complex slot machined by who-knows-what. Any clues as to how to make something like this would be much appreciated.
