Dart Cannon


Very powerfll and mobile cannon. uses a blowgun for a barrel. this thing can shoot a 1g dart at velocitys that I'm still trying calculating. With out the cannon a blowgun has velocits from 150 to 300 fps.  Impressive consitering the human lungs can put out around .5 psi. This cannon gets up to 100+ psi. You can imagin the velocity has got to be pretty fast consitering I have shot a dart threw a quarter with this one. 




Parts List


2   1" 90s

1   1" T peice

1   1" to 3/4 threaded for 3/4

1   fitting to convert from 1 inch T to bike pump nozzle (a tap will work from what I hear, still not tryed yet)

1   100 psi rated valve, I used a garden hose nozzle 3/4 inch threaded






This file will calculate velocitys.
