Interresting! Ill have a look at some of the plans in the forum regarding construction of a piston valve. If its not to difficult I might give it a go.

Yes I have also got the impression that a piston valve would do the job, but unfortunately its impossible to buy the prommising Supah valve from Spudtech because they didnt reply to any mail or voicemessages for two months now.

Do anyone have experience of twin valve Launchers? Im currently working on a Pneumatic launcher almost similar to the Spudgun Technology Centers compact Launcher TBL250LP which I shall use as an effect in a comedy show. We want to shoot out some cloths 40-50 feet, not more, but Im anyway considering...
