I just went to Vans Warped tour with a bunch of awesome bands. And I've been to a Bullet for my valentine/All that remains/(some other band that i forgot the name) :? And TSO (trans siberian orchestra) if you classify that as a concert, and the worst concert Ive ever been to... Santana!!! I havent s...

Yep I got the idea about the oxygen instead of air I dont really want to invest that much more into it anymore... oxygen tank- +-$80 regulator- $50 hoses and all the fittings- $50 $180 not worth it to me... I think the biggest upgrade Ill do is make the barrel longer. HGDT says it needs to be 33ft l...

Yeah I am interested in the chamber pressure but I havent seen anything new with that... am I looking in the wrong place? Oxy/fuel ah Ill stay away from that... nothin wrong with good ol' Propane! And DDT... thats the thing where the old meter tool that was used was wrong and theres a new formula ri...

Interesting looking hybrid you've got there, and that flange setup would deserve a ghetto award no matter what it was on. Looks like you should take a gander at more current hybrid technology, and make this thing a real beast. Ya I know but its only ghetto because it was poorly executed. I could ha...

Thanks guys!

I know it does have potential to be better but for right now thats what it is. My firend may be giving me a full size SCUBA tank soon, so maybe that will make me want to build a bigger one!

Alright well heres a small story about the life of this cannon even though I know that 9 out of 10 of you guys will not read this and go to the pictures first (I'm guilty of that :roll: ) Anyways I've been on this forum for three years now and for the last year or so other hobbies hit me in the face...

Yep I agree with that aluminum foil is easy and I can figure out how many sheets I need very quickly.


Im also going to try milk jugs

I dont know about soda cans though becuase I just think its kind of thick

Aluminum cans might be good I tried that the other day to pressure test the chamber

Any guesses as to what the burst pressure would be?

I looked in the wiki... and searched the forum and couldnt find info on burst disk material. I have a hybrid very near to completion just need to fool proof the ignition system and trouble shoot a few ignition kinks... anyways I have a 1 1/4 steel union and i was trying to think of some burst disk m...

When do they ever come "full" ? I think you need to remove yourself from in front of the computor and do the world a favor and beat yourself.

lol wow dude a lil harsh dont ya think...


And its Harbor "Freight" I stated that in my first post...

I use to have a paintball reg that I got from ebay for around $40, of course it was a piece of crap. I couldnt change the pressure it stayed at a constant (well almost constant) 120psi

Just make gradually bigger and bigger cannons and DONT make any stupid mistakes! My dad was the same way with my first one but now Im almost as big as it goes, and when I say that I mean it. If my cannon currently in production is finished it will be capable of breaking the sought after sound barrie...

Its actually in storage right now but it was about 3' wide and 1.5' tall roughly.

I have an 11 gallon tank and its not too big but it also holds alot of air for the size.

Yeah the ones you get at an autoshop like the one MrCrowley posted can be filled with a bike pump but it going to take a hella long time.
