I wish people would stop posting such standard cannons. A word of advice on your ignition, endcap ignitions have been known to shoot off the back because of the thinner PVC. After your reducer get a male and female adapter, (male on the barrel) and you can screw the barrel off, stab a potato into the breech, screw it back on, no ram rod needed. The male adapter on mine cuts potaoes nicely and airtight.

I agree, most of the guns I post look like crap, and so do a lot of other ones. This gun is good, it looks good, and is functional. I could care less about appearance as long as it functions well.

Rambo, I for one happen to be impressed with your guns, because they use a fuel source that not many people would think of. They are inginuitive and creative.

So what if this is a basic cannon? It works doesn't it? And I for one happen to like green paint. For a first combustion it's a great build.

I do agree though, get a different ignitor though, becuase that could blow out on you.
