burst disc?

Unread postAuthor: Chimps » Sun Feb 11, 2007 4:05 pm

what is a good material to use for a burst disc that would blow somewhere between 100 and 140psi range? I'm making a pneumatic granade. (Pop bottles mabey?)

grenade? hows a burst disk gonna help?

umm i think that is an unsafe pressure for somthing you may hold that is small and that you throw. i make mine outa milk jugs and anyhting like that but thats for safer pressures, i sugest you just knock off about 60 psi to what you want, at least.

so milk jugs burst at what pressure? 80psi was the min. pressure i was gonna use ... uhh so what about pop bottles what psi can they handle???

I'll probably put padding around my granades anyways so the pvc doesn't crack when it hits.
