Seems like the mini is the new fad. Ah well, it cost me nothing to participate in this one!

Its a mountain dew bottle w/ a 1" galvanized coupling jb welded onto it, and my 3' .5" and 1" barrels thread into it. According to ratcalc, with my .5" barrel the ratio is something crazy like 7:1 and the 1" is 1.5:1. Well actually I had to do the .5" manually since ratcalc doesn't support it. but.. yeah.

The BBQ ignitor I'm using is kinda old and doesn't spark a lot, but once it gets going it works all right. Good enough for this purpose. maybe I'll break down and buy a new one sometime.

My electrodes are 2 machine screws that I thankfully found at my friends house, those are jb-welded into place. eventually i'll solder or jb weld the wires on, but for now I'm gonna use duct tape. heh.

thats weird and ghetto its like a cioke bottle combustion gun! real weird it might pack a punch but ur design not mine...

[Condor]

seems like it would just blow the fuck up

[CS]

Thats wierd that Condor said that because ive also wondered how they handle the pressure. People use pop bottle plastic for burnt disks and they dont handle the pressure. Just wondering.

[iamthewalrus]

well theres a phumatic coke rifle made by boogieman i think and he pumped it to 160psi, so the combustions pressure shouldnt be a lot compared to that.

[theexp]

Coke bottles can definatly stand teh presssure, because hybrids use cut up coke bottles as burst disks, hybrids reach up too around 200 something psi.

Also while all sealed and in a cylander like that, it will flex and expand slightly to absorb some pressure. It will be fine. Just make sure the fuel mix isn't too rich and you light the bottle on fire.

I have got a few coke bottle pnuematic guns they work just fine and i got one of those coke bottles to about 164 psi before it blew...was realy loud but that cannon would only be making about 25-30 psi of expansion presure so it's all safe.

hey there, i've had a pneumantic canon, with 1.5L bottle, and it worked very great. a plastic coke bottle explodes to 10 bars, it make 160 psi...i'm making a combustion canon, and i was wondering if using a fireextinguisher as combustion tank was ok...? can somebody answer?

[boilingleadbath]

Oh, come on here...
You have a very thin walled PET bottle shaped in a sub-optimum way for containing pressure, and it's still 'safe' to put 100 psi in it. Now, you have a thicker walled steel bottle that is shaped pretty well for containing pressure, and you have to ask if it's safe to put 50 PSI in it?! What's wrong with you!?

[Rambo]

I'll use a pepsi cola bottle(2L) and another bottle around it.The barrel will be from tin leght metal.It will lounch funels.

Ive made a counbustion plastic coke baotel befor. its a fun one. but it sumetimes males and is runeded extremaly fast. so u got to skack up on empty coke bottels. i find my in a dumper

[spit_spud]

nice combustion gun, i made something like that, almost the same, the chamber is big enough to compress the air int the lid, but one problem using a copke bottle, it shrinks because of its made of plastic, but anyway nice spud!

[ballad of NJ]

coke bottles i used those for my 2 guns wprl well when you dont want to make a pvc chamber
