Friend of mine wanted a civil war replica cannon, and I volunteered my services. It turned out much better than I thought it would!
Barrel was built from 3 1/2” steel pipe with 3” bore. Breech is a 3” circle of 1” thick steel with 4 weld passes. Shape around breech was made by welding/shaping five pounds of 7018 welding rods. Bell of barrel was made by welding and hammering a 1/4” x 1 1/4” steel strap. Trunnions were made from a hydraulic ram.That's very cool, but you know the rules.... Give us some specs orr at least some details!
The pipe I used is schedule 160, and I should have mentioned that. I got it from a friend who makes cannons for re-enactments. Didn’t build it to shoot anything, just to make noise, and told the fellow I made it for NOT to shoot anything from it. I provided some 1” thick 3” diameter wood discs to make a bit of pressure. I also told him what you said about the powder.Drop a ball on top of the powder charge and you've got a nice looking pipe bomb. That is one dangerous creation you have made. Cannon's have very thick walls for a very good reason. At least go find a piece of heavy wall Schedule 80 A106 or thicker pipe and get some Cannon powder. FFg is way too fast burning and generates too much initial pressure. That thing WILL blow up!
Thanks, I enjoyed building it, even though it took several months to source parts and assemble. Now, my wife wants me to build another for us to keep....If nothing else, you seem to be one hell of a craftsman.
Where does the line start for the Gatling Gun? 45-70?
Just kidding of course. I'm not so sure about the FL folk.....they're a little out there. And I like that.
