You need to use poly-ethelene like the gas company does. If that ---- breaks, it will just bubble out the side. Great fun though.
ya, i always use the black stuff (thats what your talking about right?) we used the white stuff and had one blow up once. |

The "ABS" or as many call it Awsome Black Stuff, is much stronger, but also more expensive.

http://img.photobucket.com/albums/v3...x/IMG_1243.jpg ^^^^ 92"x2" barrel, 31" x 4" chamber. powered by metered gasoline (you guys know about the stoichometric 14.7:1 ratio ) and will easily put anything that fits, through plywood. safe to 250psi, but will never make more than a 40psi spike being combustion. being the only potato gun topic here, and the only guy who actually knows anything about it.. www.spudtech.com t66 on civic < throwing a 2x4 150ft through a stone barn wall also, anyone that follows the first post, you may as well use jb weld to make your entire turbo manifold. they're about equal in the safety department. and, there is no 5" pipe. measuring OD of pipe > you, apparently. if you're going to use 2", 4 feet of it, and 17" of 4" pipe. NO cellcore. NO drainage pipe. them = not safe. you guys like to make ----... make some potato guns. $30 is more than enough to put one together |
Re: POTATO GUN!!!
I like how most of us can build spud guns that have a longer range than Hezbollah rockets ;D ;D ;D

i'll gladly write a PROPER instruction set to make a PROPER gun.. pneumatic or combustion. you guys are just too noobish to be introdruced to hybrids. basically, take a combustion, and put a union between the beginning of the barrel, and the chamber. sandwich aluminum foil in here, add fuel equalivent to the amount of bar pressure, and fire. power of 200psi with the explosive force of combustion. 15psi of air, 2 loads of fuel, = 120psi. 3 shots, 2 bar, 180psi. 3 bar is just not safe.. 250psi. 2.5" pvc will shoot tennis balls, and SDR-21 1.5" pvc will fit golf balls nicely. SDR-26 is a hair looser (.015 or so above golf ball size of 1.64-1.68") 3" will fit pop cans, 16-24oz pop bottles. 4", is rather huge.. |
