- new member here> Hey gang, I mounted my cannon
on a caisson, now it's a howitzer. I can launch a 2"
potato a measured 275 yds. using aquanet hair spray. My
howitzer has a 5' barrel with a 3'x 4" firing chamber. I
utilized a 2" U to minimize the overall length. I used a 1
1/2" wooden dowel to suspend the gun on the caisson,
which I made using scrap lumber and bicycle tires.
Recoil is minimal. have fun
