Sorry, my last post should've gone with this one.

Anyway, this is a design for a tennis ball launcher that i will be making as a Christmas present for my younger cousins. The only thing that will be changed is that the chamber and barrel will be shorter (barrel will probably be closer to 1') than pictured, since it will have to be pressurized via bike pump. Valve is 1" modded sprinkler valve.

A fairly large chamber to be filling with a bike pump. Also I would move the top 90 angle to the chamber side of the valve and connect the valve directly straight to the barrel.
