I have a VZ 24 action that I have thought to make into a takedown rifle. The last one I did I made it to unscrew with full threads, this one I would like to make an interrupted thread so the question is....
Since I cannot broach the receiver is there anyone that could be recommended to do the work.

don't you just remove alternating 22.5deg of thread?

I think so but the barrel and receiver has to match so it will index. the barrel is not a problem but the receiver is for me as I do not have a way to broach the slots.

Broaching would require a very expensive tool (the broach), so most would use a shaper, single point cut. (And you have to remove more material than a true broach will cut anyway, thinking of a broach through the receiver ways)
However, not having a shaper either, I have done it with a cutter mounted on a rod, in the lathe chuck, and the receiver mounted in a cross slide vise; move it back and forth.
Or use a rotary table with the receiver vertical. (Best way)
Or hand file it like they do in Peshawar.
Lots of ways to skin a cat. But to answer your question; I know of no one who will do it. I have no time.

i would think interrupted thread might be dicey for a high powered rifle. ok on a 30-30 but not a 300 mag. over time might develop headspace issues.

Plenty of English TD Mausers that still work 100 years later, in heavy calibers.
