Perhaps building/cutting the reciever in two pieces, carving out your
bolt lock on one side, then some good glue? Tom

If I am picturing this correct, you could do that with a router with guide
bushing and a jig. The jig can be flat faced for the base of the jig, and
use a cutter bit long enough to reach as the fitting curves away.
Might this be a quick disconnect dust collector fitting?

No, he is *NOT*. "BNC" is a very specific reference for a particular type
of "nominal 50-ohm impedance Co-axial cable connector" for RF use -- where
the connector 'innards' are impedance-matched to that type of transmission
line. The 'quick-disconnect' feature is what distinguishes it from a "TNC"
("THREADED Neill Concelman") connector. "Bayonet" connections existed _long_
before Neill and Concelman developed their _constant-impedance_ connectors.
Including, _bayonets_ -- believe it or not! -- which were affixed to the
muzzle-end of rifles with that push-twist-lock mechanism. All the way
back to the 1670s
Many other things use 'bayonet' fittings. e.g. automotive tail-lights, and
dome lights,. bulbs for some slide/filmstrip/movie projectors, panel lights
on many kinds of instrumentation , photographic flashbulbs (remember those? :)
etc., etc., ad nauseum.

Bayonet fitting *is* the correct name.

Note: the cut-out is usually _J_ shaped. Push-turn-release, and the spring
at the bottom of the hole pushes the thing up into the locked position.
this way, it can't _rotate_ loose, and then come apart.

5-axis CNC milling machine? <grin>
dentists drill?
Does anybody make a right-angle attachment for a Dremel Moto-Tool (or similar)?
Seriously, probably the easiest way it to take a piece of tubing of appropriate
diameter, cut the J path in that from the _outside_, and then fit that already
cut tube into a cylindrical cut-out in the main wooden piece, whatever it is.
You can make the bottom of the hole _just_ big enough to hold the tubing, and
drill it out larger where the 'pin' will bottom out at. then fit a 'ring'
around the top of the tube, to hold it tightly in place. small cut-outs in
the inside of the ring, to let the pin(s) pass.
Trying to cut the slot _inside_ the hole, is *really* awkward unless you're
using a _big_ diameter piece.

You're looking for a Bayonet Neill Concelman connector, (sometimes
erroneously called a British Naval Connector or Bayonet Nut Connector.

You could use a metal (brass?) tube for the inside fitting. Make the
J-shaped slots in it, and test in on the male piece.
Then glue it into the recessed hole. A chisel can cut out the wood
that gets in the way.
The brass would be nearly invisible when assembled.
Of course steel would be stronger.

Epoxy, if it will be subjected to a lot of stress, or if you need to fill
gaps. Cyanoacrylate ("superglue") otherwise - that's how pen turners attach
the brass pen tubes to wooden blanks.
