this is my first combustion after building a few basic pneumatic ones, this cannon is very simple with a 2 inch diameter barrel and a 4 inch diameter tank with a 45 degree conector with with a 1 1/2 drain cap and at other end is a simple round off cap that i found in my garage.
the reason i used a small drain cap is becaues of the price and what few parts i had laying around. i used a basic BBQ igniter and two machine screws. also for all you high end cannon builders out there, i do plan on painting this eather in red,white, and blue or as the picture below shows. let me know what you think. 8)
this is not me. its a buddy of mine
