Schedule 40 PVC in 4"x36" long. One end cap, reducer to 2" butterfly or ball valve (2") and 2"x36" sc. 40 PVC. Air chuck with threaded bottom.
Glue pipes together, in obvious configuration, and drill hole into end cap and screw/glue chuck into it. Close valve, add tater, connect air hose inflate to desired pressure, aim turn valve, repeat.
I never went over 55psi, but that was more than enough. Few critters met their maker with that cannon and it was completely legal too.
Have fun
