			Fifth version of my M-55 cannon, and the second model of my metered propane guns, i made it for a girlfriend, improved my latest design and created a better and more powerfull gun, and added a girlie touch.

Cannons to left of him,
Cannons in front of him
Volley'd and thunder'd;
Storm'd at with shot and shell,
Boldly He rode and well,
Into the jaws of Death,
Into the mouth of Hell
Rode the Tombstone."...

I'll go ahead and answer that it is to hide the wires coming from the igniter, and he is likely using a chamber fan due to the presence of the project box on the side.

			I saw the project box but that could have just been a kill switch for ignition. I saw the pics of the cannon in photo bucket and there was a pic of the inside of the chamber........ without a fan.  I would think there would be a fan present considering all that work. I just didn't see it in the pic. Thats why I questioned it.
