Ghetto Pneumatic - with damage shots

Unread postAuthor: The Kid » Tue Nov 20, 2007 7:19 pm

Chamber - 600mL saxbys soft drink bottle
Barrel - 1 foot of 1cm copper (i think its 1cm)
Valve - slightly leaky metal ball valve (don't know the size)
Fill Valve - pop in rubber schrader valve sealed with high strength epoxy

I build this gun in half an hour with around $15, It is acaually broken right know and i really don't see the point in fixing it. The primary ammo was AAA batterys fired at around 100psi, they shot quite well and could clear my street.

The target - 3 tiles clamped to a brick

very very ghetto...

Now time for a sprinkler valve for a good amount of power.Ball valves really are crappy they dont give you much power unless spring loaded in my opinion a burst disc would seem more ghetto anyway.

i think a sprinkler valve would be a bit of an overkill on a ghetto

oh okay thx a lot they work now i love it really gehtto and simple.

I might watch out with 100 psi on that bottle. forgot what the pressures on them were i think someone tested it before. if its a coke bottle its probably fine because those are made thicker than other bottles so they can stand the pressore of shaken up coke

thats why i love it the gun is so wercked and destroyed. also if you make anothe one like it not worth a guage. but i would sugest uf your making one like it use cpvcso you can shoot paintballs. i forgot the size of the cpvc i think its in the wiki.

SCC rules (society of crappy cannons) dumb idea just had to post it
