A 1/5 Scale Napoleon Cannon
Jonny:
Noticed earlier your videos. Others members will learn a lot more than any other book or videos I have seen to date. Swear blind most of your practices image exactly mine except for the glasses.
Were the originals brass, most are cast.
Bet that goes with a boom and respectable shock wave. 10G Winnies used for the boat race test fired indoors just with primers bellowed the windows out. Walk outside, look around, what was that.
TLGriff:
Thanks, it's good to hear the videos are being watched. Hopefully they will help to get newcomers make projects sooner.
The original barrels were cast bronze. I would have liked to cast this one but didn't have the capacity for that big a pour.
The report from this thing is deafening for anyone closer than 30 feet. You can feel the concussion in your chest when it goes off. :clap:

Mr Griff-
Thanks for the inspiration.
I may try making my own Black Powder cannon barrel. I would like to know just how you attached the trunnions to the barrel. Just guessing the order of machining operations....drill/bore/ream the barrel bore....drill holes in the side of the barrel for mounting the trunnions, re-chuck the barrel and then turn the barrel profile....machine the separate trunnions, install the trunnions and braze them onto the tube....finish the barrel, etc. Would that be about the correct machining order for machining cannon barrel?
Just curious. Years ago I had a barrel cast in iron from a wooden pattern that I turned, and then had the barrel-casting drilled and lined by South Bend Replicas....so, I really didn't "make" the tube, I only finished it. I mounted the tube on my own homemade, naval-style carriage. I was a nice project. That was 30 years ago. I still have the cannon, but I don't shoot any blank-loads....the noise drives my dog crazy. It also attracted the wrong attention....and I felt that it was just a matter of time before the NYCPD "confiscated" my antique cannon. So now, I want to try turning some smaller-size barrels from scrap steel. There's still a spark of little boy left in this old geezer! I always loved cannons!!
Love your cannon. Really nice work.
