<div align="center">6 Inch Cannon

Provided By - Juscuz's

Notice the custom plug, local plumbing store was out of 4" cleanout plugs. I made my own. it works VERY well.

I used a 48 inch long 2 inch barrel.

You are correct beebs. I do believe that's just for comparison, because those tanks are somewhat big.

acetylene and oxygen are used to cut through steel, it would be NOWHERE near safe and would hit about a 9.5 on the dumbass meter

Just because they cut through steel doesn't mean they will when ignited in the chamber? Propane can cut through PVC but it doesn't when we use it as a fuel.

I'm intrigued by the concept of an Oxy/Acet gun, but I doubt I'd ever make one. Even just a pure Acetylene gun is too dangerous. Besides, it would be a bitch to meter out Acetylene without having it blow up on you.

It would be cool alright, as long as you arent the one holding the gun :D

NOTE FROM PIMPMANN22: Holy Shit! Stop kicking up dead topics! Bad things happen when you mess with the dead. And in this post you contributed absoultely nothing! This came after reading over ten posts that were of the same style. Do you really think its worths anyones time to load a page then scroll to the bottom then read this? "It would be cool alright, as long as you arent the one holding the gun :D" Didnt think so, dont do it agian.

wait i have my book about buillding cannons called backyard ballistics and they made a cannon that uses acetylene. it said use a tiny amount of bandsite and dump it in water. that makes acetylene. then you just lite it through a hole (witch would work crappy cause it would let out all the pressure) and bam! its called the carbine cannon and its made of pvc and pvc primer and cement. if you want i could get a pic of it.

For the oxy/acetylene gun you'd probably want something like a steel barrel and combustion chamber to be surrounded by concrete.LOL. It'd be in a permanent place for sure. Plus you'd need a heck of a range to shoot it down.Then it might be safe enough to stand close to it.
