Thank you
I should have been more clear with the second rendering. There are two carriges that run on the 80/20 beams. The front one is connected to a PVC plunger and is held to the front of the track with surgical tubing. The second carriage is connected to the lead screw. The second carriage is powered forward after each shot, where it latches on to the first carriage using a pair of pistons and then draws the whole thing back. Its like cocking a crossbow. When we want to shoot the latches release and let the plunger (and first carriage) fly forward and punch the ball into the air.
What is not shown in the rendering is the surgical tubing, the plates that attach the plunger to the first carriage, and the plates that attach the lead screw to the second carriage.
