I just got started on this one. It is a 4 inch*5 foot airtank and a 2 inch barrel*7ft. barrel. it is going to be huge. but it needs a fast valve know any elctronic valves.

I dont think an average sprinkler valve would work so you might wont to try to cut your chamber in half and use to very large QEVs. Ok that was me day dreaming.

Go for 2 Supah valves actuated by 2" pnematically modded sprinkler valves that in turn are actuated by 1" pneumatically modded sprinkler valves that are actuated by 1/4" ball valves. But if your name isn't Bill Gates then probably just a piston valve.

you can always put one on yourself.......
in the upcoming presidential election, there will be several candidates who will be running, one of whom is Hillary Clinton. Now WAIT A SECOND!!! I though there was some sort of rule that prevented someone from serving more than two terms in office. Vote Against Hillary: Presidential Elections 08
