can someone tell me what psi of mapp gas you need for a 1x mix , 9.what

[MrCrowley45]

It's not so much that you can't calculate it but that you haven't bothered to research it nor understand that only one type of fueling method (which is not used on this hybrid but my other hybrid) uses a constant pressure figure for each shot regardless of chamber size. That is called Manometric metering.

Do some more research and then I'm happy to help you.

@The0atomsmasher if you can't figure that out, you really shouldn't be building a hybrid

[duder145]

Are you with advancedspuds? Just wondering cause they have something very similar to this.

[MrCrowley45]

@duder145 No, i'm a fan of his work though. Don't think he still updates the website. Hybrids aren't that uncommon in the spudgun community. Just check out: spudfiles dot c.o.m. I'm a moderator over there.

[cablejerome]

[The0atomsmasher]

@MrCrowley45 thanks 

[drewnickel]

love the gun dude, atleast some people realize that ballvalve guns are becoming obselete. also, I'd think you probably have a very happy life, as would anyone who makes an "air cannon" that can rival a 12ga

Burstdisk wtf there are people with brains at youtube!!!

Sounds good, still looks a little complicated. If you go hydrogen you don't have to mix gas and air. Check it out at hydrofungun. By the way, if you use just a little acetylene and oxygen you'll get the same bang for your buck.
