Today working on the pneumatic shooting mechanism, we have used a 20 inch piston with a frisbee recycled from last years game to hold the game ball.
We have created a ramp/guide for the ball because shooting the ball at certain angles made the ball fall off the frisbee before the piston got to full length. The ramp is unstable at this time, so we need people to hold it in place to shoot. Here is a picture of that together with our frisbee piston.
Having a vertical shot we have gotten the bottom of the ball to about 80 inches. Our goal now is to get the ball over the truss, and which doing that we can get the ball in the high goal.
