That looks like a mighty fine cannon!

I like the all black look too. Is it just the ball valve that releases the air?

First post!

Thats really nice mate. Keep up the good work.

i updated the chamber size from 20oz to 24oz it has alot more power

Merged:

i upgraded it again by using a o ring to seal the breech it improved the distance greatly now u cant even see the paint ball when it goes

That sounds awesome, maybe you could try get some chrony results for us?? +- how far is it shooting then?

well i dont have a chrony but i shot it in my basement 30 feet and it was as soon as i opened the valve and a paintball goes farther than i can see it

wow u can put 110 psi in a soda bottle? i always wondered what a safe pressure they could hold. btw i like that tape job, looks like a nice canon!

Posted: **Sun Jul 01, 2007 11:07 am**

yea i read on here some where that 110 is the safe pressure and at 120 the bottle should explode i accadently took it to 120 once and nothing happend so sum times i put it up to 115

ok, a moderator already told you twice not to double post
do you not know about the edit button?

anyway mythbusters took a pop bottle to bout 150 psi before it exploded so the pressures that you are using should be fine
