hi, for my first lathe project I would like to build a deck cannon.
anyone on here ever build a small cannon?
will use a small firecracker in the breech with another one with the wick faced to the breach so it blows up in the air when fired.

even tho the firecrackers are small I want to be safe with material and thickness

if anyone can help out that would be great!
(also tooling?)

regards
