<div align="center">BIG RED CANNON

Provided By Luckythirteen - <a href="http://www.koolpages.com/potatohell/">h ... tohell/</a>

This is my newest combustion gun. It uses a 100,000 volt stun gun to ignite the propane. It has 5 sparks inside the clear combustion chamber. The riffled barrel below will soon be used for this gun, I'm waiting on my quick release from banjocorp (Parts 200A 200B) I'm also going to put in a chamber fan. I love shooting this thing off at night!

Here it is. My latest combustion. This picture shows it with the chanber fan inside and the project box on the side that holds the batteries and the on/off button.

What are the dimensions of your combustion chamber?
What are the pros/cons of a rifled barrel?

its a 4"x12" clear chamber from spudtech and i dont think there are any cons to a rifled barrel, except joel can only rifle them out to a certain length

it think that if u use a cylindrical ammo, the barrel will leak through the groves, unless it is a fruit/vegetable that takes its shape.

Yes... metered propane is consistent, cheap, and more powerfull by an unknown degree. Non-metered propane is little better than the aerosol propelents... because it's the same thing, almost. (read the ingreadients some day)

check out the burnt latke site, I remember they had pressure testing comparing propane to other fuels, the next closest propellant being static guard.

It makes a world of difference. Its cheap, fast, easy to handle, very consistant, and best of all it doesn't leave nasty residue on the contacts and your clean out cap.
