D'Oh! Hit send before I was done typing...
This is more of what I had in mind for a first cannon idea. Any comments?

You can do better than that. Make a half scale replica 6 pound field piece or naval gun.
You want something that makes a nice bang or, in case of national emergency, shatter a junk engine at 400 yards.

If you want a cannon, make a cannon.
William Green had several plans in HSM, Projects in Metal and Modeltech. Naval gun is from Jerry Howell plans.

Older brother has a 1 1/2" bore cannon capable of being slung over a pommel of a saddle.
ANother soldier carried the carriage. Made from steel, heavy as heck.
It is a noise maker. I heard the soldiers shot chain from like cannon at advancing troops.

I had a golf ball mortar mad from 8" 4140 seamless hydraulic tubing. weighed about 120lbs on the oak beam base. F-U-N! cannon fuse was a PITA

Thrud, don't know about getting cannon fuze by mail where you live, but at one time, it was available from Dixie Gun Works, Union City, Tennessee via US Mail. Personally, I go by the local fireworks stand during the "season" and buy a pack of Black Cat firecrackers, with the long fuses and this will keep me supplied for a long, long time. Oh, I pull the fuses from the 'cracker and throw the "go bang" part away.

How thick were the walls on the tube? Do you remember the size of the powder charge? How far would the beast shoot? Cool idea! Got any photos?

My old 1" bore yellow brass cannon died an ingloroius death at one of my friends hands. Even though I told him it was black powder only, he loaded it up with a half a 38mm film bottle of double base nitro cellulose handgun powder. They found a few scraps of wood from the naval carriage base and the last three inches of the muzzle. I was none too impressed when they returned the remains.
Any one interested in quoting a job for a 24" long (all other dimensions scaled to the length) yellow brass barrel for a Col.W.Congreve 3lb Grasshopper or Butterfly?
Check out this guy. Crazy as a bat.

Not only dangerous but stupid!! Holding a PVC pipe with an explosive inside and lighting the fuse to propell a golf ball?
When I was his age I built a black powder cannon, but I wasn't dumb enough to hang on to it and lite the fuse!! B.G.

Back in my stupid but lucky youth, I used to make my own gunpowder for July 4th fun. Mixed crushed charcoal (from the old man's grill supply), potassium nitrate (my pop had a can of that, too. Reason unknown), and a touch of sulfur from my chemistry set. It burned like a flare for about 5 minutes and left a lot of burned sulfur on the curb. As usual, I got lucky (ignorance is bliss) and still have all my parts.

I have a good friend who is blind and has lost most of his right hand from playing with explosives at the age of 10. He loves machines and machining, but can't do anything. I have made engines and models for him.
