I picked up a piece of 1" brass rod (it's former use is unknown) at a local scrap yard to use as my first cannon/mortar piece. I originally was going to use a 5/8" piece since that is all I had laying about. I have attached a copy of the plan for it, based on the information on this board...this place is great.
I plan on scaling it to fit the 1" OD of the mortar, but I have a few questions. Due to the small scale and the fact that I am cheap, I planned on using .177 BB's for the bore and shot. Now I am able to enlarge the bore, but what would be a safe caliber (this will be my first attempt) to "shoot for" so to speak. I DO want to fire it, I mean what's the point right? I figured that steel ball bearings or something like it would work. Any and all help (and comments on the drawing) would be greatly appreciated.
Thanks.
