Hello all,
Just thought I would share some pics and vids of the new combustion cannon my friend and I built.
This cannon uses a 100k volt stungun, metered propane injection, it has a clear chamber from Joel, a 1.5" rifled barrel from Joel, and it utilizes banjo fittings for quick breech loading and burst disk capabilities. A chamber fan with blue led's is also used but it stopped working today possibly due to its exposed shroud around the fan motor.
Less talk...more pics

A video of some blank shots can be found at: http://www.clemson.edu/~wesleyj/vids/combustion.wmv

The first shot is a potato, (it hits the top of one of those trees), second shot is just blank, third shot is single burst disk, fourth shot is double burst disk. After having my ears ringing from the first burst disk shot, i wimped out and got some ear protection

More pics and shots of the assembly of the cannon can be found at: http://www.clemson.edu/~wesleyj/combustion.html[/img]
