rolled threads for screw shells

[_wompy_]

Has anyone made or worked with rolled threads for screw shells? I have a project I'm working on. I need to make some thing like antique shot gun rod cleaners the male and female parts. https://www.rubylane.com/item/161834...ning-Rod-Three

any help where to start would be greatly appreciated

They are die-formed; unless a large quantity is needed, this is a time, equipment and labor intensive endeavor. It's possible there are commercially made versions.
Are threads a requirement in your design? There are many simple and light weight alternatives; cervical springs, ball-lock, detents, straight ferrules [fishing rod], lug pins, quarter turn fasteners [like Dzus], bayonet fittings, interlocking flats with collars...
