i dont think you really need plans for the gun its so simple if you can identify basic pipe parts you can build it no problem. it cost me about 30 dollars to make, the valve was 20 by itself, everything else was either cheap, or i had it laying around

well, thats a quick connect, if you're going to use an air compressor, they fill much quicker than a schrader (bicycle type valve with 1/8" NPT threads) valve, but you need to have a ball valve on your air line like i do to stop air flow when you are going to fire it

sam, your image leads to a myspace code generator. I suggest you remove that, intentional or not. I would personally consider that spam.

spudshot, how does that barrel work out for you? i was just wondering because i built something similar out of galvanized steel, the barrel is 30" long and it has a large ridge down the side of it that stops anything tight fitting from going down. i just went to home depot today, and checked all of the 1/2" metal pipes, and they all had that same ridge. i just decided to use a sch 40 1/2" barrel, but i was wondering if you had this same problem.
in the upcoming presidential election, there will be several candidates who will be running, one of whom is Hillary Clinton. Now WAIT A SECOND!!! I though there was some sort of rule that prevented someone from serving more than two terms in office. Vote Against Hillary: Presidential Elections 08

I like the color choice. How much does it weigh? What all have you shot with it? That valve is awsome too. I am considering a valve like that on my next cannon.

well since someone has already kicked up this old fourm i mays well say that i absolutely love that cannon. i think you should get a higher presure valve and blow gun and use helium or something really high presure and i bet you could break the sound berier :wink:
