« on: February 19, 2009, 02:33:57 AM »
 I doodled this up the other day...



 A simple small cannon to shoot a 1# lead ball.

1# (1 lb) lead shot are almost exactly golf ball diameter.

4" diameter is a little under size for 1 lb shot (1.7") if you use the 1 caliber wall rule.  However, it is the same proportion as a Bronze 12 pounder Napoleon.

 It will be hefty but manageable. I don't want it to flip. Yes, the nuts will be for adjustable feet.

 With a 2 7/8" OD seamless steel tube inside of a 4" one with a welded/pinned breech and a vent liner it'll be plenty safe.
