Im debating wether or not to delete your post "nano-nater". First of all let me thank for being one of the few people that make the whole of spudgunners look bad. I beleive what you have just barely said is admitting to a crime, perhaps destruction of personal property (not sure). I must ask you one thing though is the "cement wall" that you were shootin at vertical? If so how did it hop? I could see if it roicheted but you said "hop". To prevent future damage I would suggest not to shoot in the direction of houses, other peoples crap, valuable stuff, etc. Dont worry I will proably come back and delete this but Iam dieing for a responce as to why? I hope you dont see the "po-po" either. When I first read it I thought it said poo-poo.

something in that story doesnt pan out, its uncool that you didnt find whos window it was and rectify the situation.

tha t is a cool copper gun tho, pretty great pics too. g/j.

Not cool. You're lucky you didn't get caught, even if it was unintentional, you could still be fined a pretty penny.

i'm wondering how much pressure a 28mm of diameter copper pipe can handle? Cuz i actually have a soda bottle with glued diaphragm valve, and i put it to 60-70 psi, even at these pressures, recoil is substantial and with water, it breaks you the arm!! so how much pressure can 2mm thick copper handle?

Posted: **Sat Dec 10, 2005 4:16 pm**

500 PSI is a rough guess. Even though, I wouldn't take it above 250 if neccessary.

Posted: **Sat Dec 10, 2005 5:28 pm**

True, the copper may be capable of taking 500 PSI. However, I don't think the valves are rated that high... 250 is pushing it, but shouldn't cause it to fail - most ratings have saftey margins in them.
