Re: Over-engineered T-Shirt Cannon

Some specs for the cannon

Drivetrain:
-4 Four powered wheels, chain drive with 12:1 P80s
-2 Rotating Casters

Cannon Base:
-Custom machined rotating base with gear teeth around the edge
-Powered from the edge using Bane Bots 550 64:1
-Tilt using CIM + Bane Bots 108:1 P80 gearbox

Cannon:
-All the parts were either CNC milled or laser cut
-Barrel Material: 3" OD, .125" wall thickness aluminum tubing

Pneumatics:
-SCUBA air source (regulated to 140psi off of the low pressure port)
-Custom machined/welded accumulator tank (6" OD .5" wall alum tubing)
-1.5" air piloted Numatics poppet valve

We only have the single shot capabilities running right now, we are planning on having semi-auto belt fed capabilities as well. I have included a CAD rendering of the completed project. Our tested range right now is 75 yards.
