(sigh) why would I "obviously" be naive about guns if I dont give a shit about my grammer? Really, idk what to tell you. well mr.smarty pants, ive only seen one computer banned at school soo...uhhh guess youre a stupid baboon then? So I see that you do know that chimps are pretty smart eh? I love th...

yup ane then the air would leak out of the hole the string goes through instead of rupturing the burst disk...genius...I suppose youre in the .2 classes huh? you smoke pot?

go ahead and report me there are about 100 computers at school to get banned from spudfiles but i honestly dont care anyways... why would you want to use CO2? do you even understand that you would have to carry around two parts? that's ridiculous! if anyone here has actually used their guns for a pu...

for PVC Arsenal: Excuse me I'm not new to your damn pointless forums. I've built guns since I was 5 and Ive been banned here twice. HA! for noname: If you were to be playing paintball tell me how the F you would be able to use the granade posted. I'd honestly like to see you pull out a bike pump wh...

ya know what, I will never do that research thing because i can just post the question and someone will always answer. And someone will always PMS too. I dont care how I spell my words, thats how ive been banned twice. Go to the grammer section and read what "THEMOST" and "THEMOST#2" have to say. lo...

wuts a QEV?

here is my idea for a new pressure activatem mine you could make... http://img299.imageshack.us/img299/5926/3321uk8.png grey-activation pad blue-pressure chamber pink-blow gun addached to the activation pad red-moded sprinkler valve green-baby powder wow... im speechless. you know that someone woul...

myesh, like i said...anyhoo id still use a modded sprink since it would make for less piping and you can use smaller chambers with sprinks, unless you use a wery small piston valve.

am i proving anything? i just think your idea sucked im entitled to that, anyhoo how is this granade idea of your practical? you have to be hooked up to a generator to use it.

Well ill post some pics when im done lol

haha dont try to eat a chimp with a loaded gun

i dont really care anyhoo since i have not and never will make a hybrid.

why dont you just put a small hole in the piston so the aire pressure equalizes and put one of those things in the back end that will release the air at a certain pressure(the ones with an extreemely strong spring) for the exaust? screw the two air chambers because that's just dumb, no offence, for ...

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.

what kind of valve are you using now? You could try something with a small air chamber that is connected to a larger reserve chamber. Between them you could put a piston valve with a heavy spring behind it that has air flow in reverse. It would shut when the air pressure is equalized in the 2 chambe...

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?)

the cotton isnt a big deal. You may not even need it. yea you could put mesh infront of it and i'd also assume that the paint would spray out first even if the cotton came out at all. Since there is no air pressure behind the cotton then it should stay in place anyways. Anyhoo, yup I've started on t...
