Some years ago I came across a glut of K frame guns at auction and discovered how easy it was to remove a pinned barrel (one was bulged). Noting that Numrich had 18" .357 barrels I ordered a few and planned to build a revolving carbine. Finding a way to thread the barrel slowed me down long enuf for business travel to send this project to the back shelf.
Cleaning the other day I came across the collection of parts and interest was renewed, hence my request in an adjacent thread for the loan of a .540X36 TPI die. I have a lathe that can turn accurately, but I am a bit leary of the accuracy of my single pointing. I have found a die holder that can be chucked up in the dead center for hand turning. Contouring and adding necessary barrel features is not that big of a deal with silver solder on the bench.
Has anyone built a similar gun? Die, anyone? Thoughts?
