Like a bad penny...
I started this project several months ago with the original bore in the barrel. This is 4" round stock bored with a smooth bore of 1 11/16" in a 42" barrel. Unfortunately I wasn't there and it's bored completely through. So, I need to slice off about a 3" piece of the 4" round stock, 45 the edges on one end of the barrel, one side of the round stock and weld it together. To insure strength, I'll use some relatively rare 3/8" 7024 rods, as shown, to attach. You can also see in my picture that I finally got around to mounting my old vice on my welding table...2 years after I made the table.
Anyway, before I bore the nipple hole for the fuse I can take it to a friend's hydraulic shop and he can give it a test of all the pressure his machines can put out. I don't expect my weld to fail, but I'd rather it fail in a controlled situation if it's going to fail.
Anyway, even after cleaning up the end of the barrel after the pressure test, I'll still have a full 42" left. Any guesses how far 2 pounds of black powder would push a golf ball? I have a minimum of a 6 mile range up at my other property. I'm sure it won't go nearly that far. Guesses?
