this was my first attempt at a piston in a tee, and it wasn't as hard as i thought it would be. the piston is 2'' dia. washers with an o-ring all on a 1/4'' thredded rod. My pilot valve is a 3/4'' sprinkler valve, recycled from an old sprinkler system, can you say "free-bie" At 80psi it will launch a gb 400 yards, in other words, it pwns sprinkler valves. it is 1-1/4'' port because it was nervous that if i went 1-1/2'' i wouldn't be able to get my piston to actuate. well here are some pics.
