Air supply Q.

I am some what new to pneumatic cannons. I am going to build an Inline Vortex bbmg for airsoft but the only thing is im not totally sure on how to power it off of Co2. So I was wondering how i could use a 20oz paintball Co2 can to power it cost effectively. I would need a regulator so i could see how much psi is being put out and be able to adjust it.

Well a cheap regulator is at least 80 bucks plus the co2 will be over 100. You defianatly need a regulator.

Not only that..the CO2 itself is more expensive than HPA.
HPA is said to give less cooling problems than CO2 when rapidly expanding and ofcourse it will give better muzzle velocities.
The last wouldn't be very important for airsoft though...ouch!
On a sidenote...I never realised the muzzle velocity is always close to 0..
It would be better to call it ...projectile peak velocity...or something...

If that is the case, then how do I Have a psi regulator and hpa tank that is portable?

Buy a portable HPA system from a local paint ball store.
I just did 150 bucks got me from 3000psi HPA tank. with paintball threads.... to 1-850 regulated psi with 1/4 NPT threads.

Is there any other route I could take for a regulated power source cause I do not just have 150 dollars laying around at the moment

check craig's list, too.
You could also use propane with a normal regulator. The problem is fumes, relatively low pressure, and a rapid decrease in temperature, thus pressure.

My setup came to around 100 dollars. I used

I wouldn't say that propane = relatively low pressure
sure the pressure will drop due to cooling effect but I don't think he needs more than 80 psi with a bbmg...also remember that propane is really dirt cheap
ohh BTW do you think that they add a different odorant to propane in the US and Europe ?? I've seen dozens of posts that suggest that propane stinks but IMO it smells nice... Am I weird or is there a difference between the US and Europe ?

Does yours smell like rotten eggs? Because that's how mine smells.

It shouldn't smell nice, that's the point. In my part of the world they add
this stuff to cooking gas (25% propane, 75% butane), so yeah, it stinks

Ah, but if it smells nice, you're less likely to look for a leak

And more likely to spend a rather unhealthy time "smelling" it. :color: :color: :color:

So are you guys saying that I would be able to use propane or no?
