Ray's 155MM Firecracker Cannon
I really love the Home Guard cannon and in my opionion it is the best of all that firecracker cannon designs.
That is I choose it to reproduce. However, after learning about the 'second firecracker'
routine, I found myself elevating the almost level barrel on the Bronze Home Guard
to get an air burst. One day I decided to make a cannon with an elevated tube and the
155 is the result of my efforts.
The bore is 3/8" compared to 1/2" for the Home Guard. This gives a little better muzzle velocity and the elevation
plan works just great!
The cannon is about 9-1/2" overall.
The barrel is 5" muzzle to breech face.
The wheels are stainless steel, 1-5/16" diameter by 1/2" wide.
I used the Home Guard design to let the weight of the barrel and drag close the breech.
The parts are 360 brass except for the wheels and retaining pins.
