Been pondering this since seen first brass return caps made years ago and also since @ADV made his wicked cool 1 piece return caps.
I checked and a couple feet of 7/8" hex stock is not too expensive.

I figured why not attempt to make some brass caps without return lines. Then add the tubes after and being brass hex it would make drilling accurately simplified due to flats to drill into. Press return tubes in and solder and done.
So I am first looking into what stock locally would be. Then access to a lathe to either do the machining or have it done.
There are a few lathes in friends posession so maybe this could be doable.
It would be simplified more if a 3 or 4 flute mill of the correct size could be found then it would be super easy to bang out caps.
Time to start measuring up caps.
Hmm...do I want that step inside or not......
Hmmm. Will see what is available and report back. So far 3' x 7/8" hex brass stock and some 3/16" brass tubing is well under $100.00
Hmm....
Wonder if .....
