20" in diameter that must be heavy and very expensive considering its stianless... I would think you will have a hard time finding fittings for it.

one you make this gun (if you decide to) promise us you won't take it to school. We don't want another Columbine situation on our hands.

lol, not if he finds a way to make it as compact as he wanted it, but i doubt he will accomplish it, hell...i couldn't do it, but I am short tempered when it comes to small cannons because of the precision and size.

This is coming from the guy who has the devil as his avatar 8)

Any way have you considered how your going to fire it? It would take one heck of a burst disc and I know of only a few expensive valvs that are rated for that kind of pressure?

I thought you wanted something a bit more portable? In any case you didn't mention what caliber barrel and how long is you chamber. I'm guessing pretty short...
