I'm building a simple muzzle loading pistol, and I was just curious about this. I am threading a breech plug, but is there any particular reason I can't screw it in and then weld it too?
Black Powder cannon's bore is .472" firing a .452" ball.
If the weld is not in the pressure area, it will work for sure. Took a galvanized pipe and cut a 1" long rod to fit tighly into the pipe. Then had a welder braze the back end. The powder charge is 1" away from the weld.
If the job is done properly there is absolutely no reason to weld it. Also, if it is welded you will have a heck of a time removing it should the need occur in the future, something I do regularly when inletting the barrel on the stock.
What jaguar says. You can weld it, but you can't remove the plug. BTW, I examined and shot an African Dogon (Tribe) made musket that had its breechplug welded on.
Are you "chasing" the threads on the breachplug using a lathe?
If so, cut the threads a little on the tight side so that a wrench will be required to tighten/ loosen.
I don't think a weld is necessary!
