I made just about the same meter Starman posted. It's a badass system. I unfortunately don't have a regulator on mine, but i did install the gauge on the meter pipe so all I have to do is open the valve and shut it off when my desired pressure is reached. It takes a little more time to meter than ha...

all I can say is wow, you were lucky to come out of that with only that much damage it could have been a lot worse like that thing could have been your head

I have an old old merlin mini stick welder a couple years ago. havent really used it too much cause i had a bunch of wet rod but if finally got some new stuff and man that thing can turn and burn now. it still needs a new electrode but hey it's still does the job.

I'm confused can i see a picture of your meter cause i'm really lost

It all depends on how compact you want your cannon. That's a question that only you can answer.

Dude if you are in the US just go to ACE hardware and get some 1/4 inch or whatever size you want and they'll have all the flared fittings reducers couplers whatever you need and a flaring tool as well. that way you can completely make your own for your custom needs.

Totally agree with Mr.C <-that rymes Heh Heh! I dont know jack about bbmg's or spring loaded airsoft just wanted to say that cause I'm really bored.

as ramses was saying you would need a centrifugal clutch in order to start it since i doubt you're gonna wanna rig up a clutch and a transmission for it. since the ratio changes due to acceleration you'll need to figure that into your gear ratio. you'll find this on CVT's on 4 wheelers.

i prefer propane meself, but ether, aka starting fluid, axe, hairspray, blah blah really anything hexane or propane or butane in it will burn. look in the wiki under fuels for more anyswers

since you said it's all one pipe and there will be no reducers, i'm going to insist you get a coupler for whatever diameter pipe you are using, and using a dremel tool or something similar, remove the ridge in the middle of the coupler and slide it to whatever position you want the sparker to be and...

I've tried eMachineshop and it's cool in theory, i'm just not technically saavy enough to do all that stuff. but it'd be cool for someone who knows how to do it.

Two questions. Why do you want them in two 4 foot lengths? and Do you want the connection permanent or detachable? If you want a permanent connection a normal coupling would work just fine to connect them together. For a detachable connection I think cam locks would be too heavy for a mid barrel att...

ok well both problems go hand in hand my answer get bigger spuds. and yes unlike what pvcpsyco says beveling the inside edge of the barrel at the muzzle will help form a tighter seal

I don't know if you found one or not yet but if you go to ACE ask them to look on Acenet. It is our online database of warehouse invitory. I bought one from them (because i work there) and it will spark almost an inch. I got it for $15 with my discount. They go for about $22 tho. Wow dude that is a...

If you put a "T" inline before the injector and put a check valve for say 39 psi to the return line going to the tank would work I've got access to a steel tubing machine for fuel lines I could start to work on the fuel injection system and if someone thinks of a better way to do the electrics let m...
