Ok, this is my first combustion cannon and its not 100% done yet, still need some cosmetic stuff, but i have all the escentials.

its a propane metered cannon with a 4"x24" chamber and a 1.5" sch40 barrel, great for makin mashed taters.

This is the almost finished chamber

Loose the Duct tape,it makes a well built cannon look crappy...Well from my view.Nice cannon though,were is the damage pics?

Might I sugest a support for the propane meter.It would be a sad day if that were to be caught on something and snap off-plus it adds to the whole proffesional build look :wink: .
