any reason why you did not use a paintball in-line regulator that is made to connect to the end of the co2 tank

wow sounds intense. Please post those pictures when you are done and give us some numbers with them.

Has anyone tried to make a pisotn valve out of a 6" Tee Joint. What do you all think will happen?

thanks check out the new pics

i know but is say NSF - dwv what is the NSF for isnt NSF-pw good

NSF - dwv ? anyone

thanks i just checked and my bushings are ok but one fitting says
NSF-dwv what does that mean

thanks for the tips, the cannon was not stable at all without the wooden stabilizer becasue the entire weight of the valve and barrel would have been on the T Joint

thanks for the help am i in danger at any moment or just down the road. and what are the pieces i am looking for going to say

you should be able to it all just depends on how your roll you t-shirt

the more the air and the faster the air gets to the tennis ball the better. as long as you have the valve release at the same time your ok. But boz awesome job i love the attention to detail. It really shows your pride in your work.

Here are the remains



Don't Mess With PSI. it goes to show that these cannons are bombs if not handled correctly.

3" barrel works perfect, and ya after my first one blew up and put a few stiches on my buddies hand i am a little cautious with this new one. Thankfully i am only having to fire it off at 50 psi and am achieving 2x the distance of the orginal cannon thanks to the supah valve

OK guys i think the piece on this cannon that was the problem was the cirlced t joint below. can anyone tell me if the t joint or any or piece was a DWV and would that be the problem that caused the explosion

i have a in line co2 air regulater that i usually feed in the pressure at 50 psi and for safety i have a 125 psi safety valve. what is the problem with DWV?
