i am about to ask a VERY noobish question but how do ou mod a sprinkler (please dont flame me for my question)

ya srry bout that last post....... i am just really tired thats all.... i will have 2 sprinkler valves, i will have at least 5 feetof 1/2 inch pvc piping that can withstand up to 250psi and i will be using this regulator: http://www.palmer-pursuit.com/online-catalog/stabilizer-male.htm with a custom...

thanks guys i no u werent trying to be mean i do need a lot more research..... i just havent been able to find a paintball regulator anywhere where i live thats all.... how much do you think that this cannon will cost me? it wont have any special features it will be muzzle loaded.

that helped but where could i find a regulator that can handle that much pressure? i looked at ones today and none of them could handle 800 psi they could only handle like 150 psi . could you point me in the right direction?

i need help building a cannon but i dont know what psi the co2 tanks run at. if you could tell me i will be happy
