The barrel is made of 3/4" PVC cut to 18" in length. The pressure chamber is made from 1" PVC, ours is 18"
long which seemed to give pretty desirable results. You could make any of these parts longer if you felt necessary, but dont
make the pressure chamber shorter or you risk not having enough air to push the ammunition out of the barrel. The small pieces
of 1/2" PVC are about 3" in length, we didnt measure them. For the valve on the end of the pressure chamber we used
epoxy to hold it inside the 5/8" hole.
This is the pump we used. It was not too sturdy so if you do use this type be careful and push straight down or it may bend
the frame like what happened to ours.
Below are some pictures of the PC1 and a a couple movies of the PC1 in action. In the movies of it being fired it is pressurized
