Propane for pnuematics?
Has anyone ever tried using propane injection to fill a pnuematic? I mean if u can fill a meter pipe to like 90 psi, then why not a pnuematic? Sure you would use alot of gas, but it would be way faster then pumping...Ive seen propane used in airsoft bb guns so i figured this would work just the same.
That would make a cool fireball effect. It might explode instead though. Does'nt high pressure gas create a lot of heat, i'm just worried that it would spontaneously combust.

If you are talking about filling the chamber with pure propane then you will not have to worry about it exsploding since there is no oxygen to react with. I don't know at what pressure it does spontaneously combust at, but the only problem that could come up is if you don't empty out the air already present in the chamber before you inject the propane, that could possibly cause a problem.
i think the point is to use it like c02 is used in pneumatics, so it wouldnt matter if there was any air in there as long as it got up to the pressure you want. and if you are talking about you might have a problem with the air in there because it will explode, it doesnt matter because there will still be wayyyy too much propane and wayy to little air to combust.
and yes it will have oxygen to react with once it exits the barrell onto the flame.

Benstern also did that. He had some fun with that at the shootout about a month ago.Atlantis wrote:That would make a cool fireball effect. It might explode instead though. Does'nt high pressure gas create a lot of heat, i'm just worried that it would spontaneously combust.

Lol, propane spontaneously combust? It only goes upto 92psi normally becuase that's what it liquifies at, but I don't think anything out of the ordinary will happen... I'm thinking about filling some balloons with propane\hydrogen and stringing them to one of thoose balloon weights and shooting them into a bondfire.... Don't follow my complete stupidity, you will hurt youself, I'm a professional pyromaniac, don't try this at your home, maybe at your friends home

I don't really see any advantage to using propane to power a pneumatic.
1. Its more expensive
2. Why use something flammable, compressed air is dangerous enough
3. It's lower pressure than compressed air or co2
The only reason to use it would be the make huge fire balls but that's just asking to get blown up or end up in a burn ward.

$3 isn't too bad but a 20oz co2 fill is only $2 - $5 and would fill even a large cannon multiple times. plus it's not flammable!
EDIT:
Also consider that a 12 gram co2 cylinder is only about $.70.

yeh i have, only because i couldnt get co2 cheaply. It works really well except your dont want to fire it in an inclosed space Propane is very smelly. i wouldnt use it again tho way to expensive, unless i was going to make an bbmg i have drawn up plans for a bbmg to use propane and the best part is that it is just a standard bbmg with a hole drilled in the regulator.
