I cut, drilled and polished every part of this project.
Everything is surgical stainless except the wheels, they are aluminum.
I used a doorknob hole saw to cut the front wheels and a smaller hole saw to cut the rear. Put them on a press and polished em'up.
The barrel was actually 4 pieces that I mig welded together, then turned down on a lathe. The barrel is over 1/4" thick and about 14" long with a 1" bore down the center. (It's nice having machine tools in your shed) I used brass fasteners and hex weights on the bottom of the chassis to weight it down. It weights about 30 lbs!
It uses ffg black powder, about 3 grams... and you can hear it a mile a way... no joking! I have to use the cannon on grass because it launches back about 20' when it blows end over end. I only pack it with wadding and wet newspaper. Much louder then a 10g shotgun. I once put a 4" nail punch in the barrel and it blew it completely into an oak tree... it's still there somewhere in the middle! It took me about a week to cut and build it. I made it up as I went along so there are no plans to give (many have asked) I buy the fuse at cannonfuse.com (where I found the link for this site)
thanks for looking!
