Double Barrel Cannon (Almost finished)

Unread postAuthor: noname » Sun Aug 06, 2006 4:47 pm

This is a double barreled cannon. The larger barrel is breech loading, and the smaller barrel will be spring-loaded mag fed. The open end of the T in the chamber will have a foot long piece of 3/4" and a plugged elbow with a hand pump attached. There are ball valves on each barrel so no air is wasted. As you can see, it isn't done or painted. Again, my hand comes out right on the blowgun when I put the stock on my shoulder. I will have the barrels clamped with a sight and spacers and the magazine.

My drill created enough friction to melt the coupler.

you could but you would need two people or a spring to activate the second one and there won't be much power in the shots.now looking at it i doubt the second barrel will do any damage(the barrel on the bottom) the air would just flow straight instead of going down to the second one.

edit: woopz didnt see the sprinkler valve i spose you would just leave both ball valves open and activate the blowgun for double shooting. :oops:

Exactly so you can shoot either barrel, or both but you'd need to pump alot more.
