Hey guys, just signed up a few min ago but ive been trolling through these forums for about a week now. So ive been interested with building a cannon for a awhile now and after reading a lot of different design theories, plans, loads, etc. i think i might have something i could build and feel safe about.
The plan:
- so i was thinking about using 1080 steel and acquiring a piece with a 4" dia and 16" long
- the bore would be 1.5" x 11.75"
- the powder chamber is 1" x 1.375" (though if u look at the drawing theres a second lone hash mark, my thought is i might be able to move either the chamber back that far giving me more bore length OR elongating the powder chamber. if thats a safe possibility.)
- the trunnion design is not completely thought out yet, i want to bore shallow holes in the side of the cannon to countersink the trunnions (is that the best route) and as far as attaching it to a carrage im thinking a metal sled is the best idea welded up out of 1/4" plate.
the notes on the bottom are more likely wishfull thinking about energy and velocity but none the less if like to be able to hit a moderate velocity with lead balls. i used

id appreciate all the input i can get, im not an engineer but a designer so my math could be off
thanks guys!
