| Sorry to kick this back up guys, just wondering pc guy, with the fuel:air mix, does the tube act as a fuel meter for the oxygen or something. You mentioned above that the the valve and venturi make the perfect air:fuel ratio. I just don't understand how thats all... |

| sorry to re-kick this up but how much pressure do you think your breach loading system would hold. and does any one have a good method of holding airsoft bbs in place in the barrel. |

a breech loader doesn't really take too much psi becuase the pressure is more easly released through the barrel. bb's ina barrel allone? there isn't really anyway, a hopper would work but yea.. |

| He means when it's actaully shooting, the pressure isn't that great because all the pressure is going out the barrel. |

exactly. and if u keep the sheath of the breech loader tight it will stay nice and air sealed. |

Jolly roger~ PCGUY didnt make it, I did, he just posted it for me. The fuel is metered in with the torch, which mixes air with the fuel as it is blown through a venturi (kinda like a larger propane torch, try covering all the holes at the base and see what happens). You can even use a propane torch to fuel a smaller combustion (unless the torch has a high output, such as a shrinkwrap torch).
Does that answer your question?
Zeigs spud~ I'm not positive, it cant be that much with the setup I had there, it was enough for a small combustion, but for example a pnuematic would more than likely destroy it (the shrink-wrap tubing on there is only about 1/64" thick). |

| Man that is one BEUATIFUL gun! I just have one stupid question. You said you use that torch and it mixes the air by iteslf. What about the carbon gases? Does it not matter? I mean do you have to vent it after each shot like regular combustion? |

| Nope, dont have to purge the combustion gases, all you do is open the valve then turn the torch on, the torch blows all the exhaust gases out and replaces it with a fuel/air mix. |
