It looks like you've taped a hose barb into the solenoid hole. You should drill a bigger 1/4" hole in the middle of the valve. The solenoid hole is about 1/8" big or something.

So what does it shoot like at even 40 psi? Are you sure a ball valve would be a upgrade? You can mod your blow gun to better it's preformance.

Edit: Modding a blowgun .

I don't like it that much. seems like you could have thought it out better before you built it.

I've never seen an over/under that tall before! It does look thrown together though. Is there something in the cage in the first pic? It looks like a rabbit or a small dog behind the barrel...maybe I'm crazy.

Tapping plastic is sooo easy= for sprinkler valve.
Fiberglassing is 10 times harder.

But building launchers is a blast!!!
