so you want something safe that isnt pressurized? You can use compressed air, propane, or co2, there isnt whole lot you can use......

co2 is safe if you have a regulator.

I think a pump is really the only safe portable way. Anything else will run out and get weaker with every shot.

My idea, an idea I would use if I ever use CO2, is that you hook up the regulato to a 1 foot or so hose, to a length of 3/4" or 1" steel pipe as an expansion chamber, to a 2 foot hose coiled up in a roll, then to an air chuck. The steel pipe and hoses would keep the liquid CO2 from getting into your chamber.

you know what you could do is convince your mom that it is safe if it have a pressure release valve.

what the release valve does is when it gets to a cirtain pressure (say 100 psi) it pops open and reseals when it gets to about 80 psi. that wa it is impossible for it to go above the maximume pressure of the pipe.

A pressure release valve doesn't let air out that fast so I don't think you'd be too happy using it as your main valve.

is IS a valve, so yes it would work as a valve because it is a valve.

i think what you maen is can you use it as a fill valve and the answer is no. all it does is open up when it gets to whatever pressure it is set at. when it drops below its seal pressure, it seals again.

just look it up on google.

I will answer that with another question.

Are you strong enough to pump for awhile?
