just like that.............

if youre talking about moving 100 feet away and then firing it, i reccomend using a non-pneumaticaly modified sprinkler valve, and actuating it with some REALLY long wires and lots of batteries.

when u put the hose on remember that the longer the hose the slower ur valve will open... so keep that in consideration...

what size chamber/piston do u plan on using? it is hard to actuate it with a small ball valve if it isnt built well...

I have used this setup with about 5 coaxial diaphragm guns and it has worked every time. Of course, diaphragms are much easier to exhaust than pistons, so a piston may require a sprinkler valve, then the ball valve piloting the sprinkler.

why dont you just tie a string to a ball valve?

That's all she wrote. That setup will do just fine, but as spudthug said it will slow down with longer tube. I am wondering however how far back do you want to be when you fire it? Depending on the length, I would either use an electric powered sprinkler valve, or as hi suggested, string. However, if you want it like your diagram, then the setup you have now will be just fine.

Hey guys, I'm back from a trip to Scotland.
