    I made a real blackpowder cannon in high school metals class (graduated in 1977). After annealing it, I turned down a hunk of axle from a big truck. It was probably 1 1/2 inches in diameter and 15 inches long. I bored it .75 cal (we had a 3.4" drill.) and included a fuse hole. I rehardened it, polished it all up and built a solid oak "carriage" for it with elevation adjustment. I found wads of Steel wool tamped down in it comes out like a Roman Candle. We've used it to exterminate large flocks of nasty blackbirds by using pebbles of broken automotive safety glass as a projectile. Also set the old man's garden on fire with the steel wool one time. I should get it back out, polish it up and get it ready again.....

    Ah yes memory lane, making black powder and filling BB tubes to make fire crackers ( I have the scars to prove it).
    Then moving up to filling empty co2 cartridges with black powder! We were worried about shrapnel so I had a piece of CRS 2x4x6 with a 3/4" hole that would take a co2 nicely.
    Moving on from a potato cannon powered by hairspray I now have an air powered cannon for launching golf balls ( a good 400-500 yards). I live at the edge of old golf course and have a good supply of golf balls ( found 35 one morning walking the dog). Must have been a lot of duffers, as there were a lot in the woods!
    I did make a breach loading BP cannon but it wad stolen from my storage unit, my only hope is whome ever got it will one day get caught with it as it would be classified as a DD (it took a fixed brass cartdridge) 1" bore.

    I've never loaded any black powder gun over 8" bore. As far as hand lighting, my limit is about 5".

    What is the difference between men and boys? The size of their toys!
    Several years ago I build a bowling ball mortar out of an O2 tank. I had it setup to fire with a .22 Blank with lanyard. It would shoot a 16 lb. ball close to 500 yards using about 1/4 cup of cannon powder
