No, I have trust, but they bet me 100 dollars I couldn't make one, so Im proving them wrong.

Alright guys, my gun is going to be a Steyr, equipped with a shotgun-like blast for a secondary fire.

The secondary fire is going to be a micro conbustion, the fuel will be hairspray, put into a a small chamber, a back-clicker will be the firing ingnition.

It will be a full circle for the vortex ...

Thanks for your help guys!
I will get started after May/20 (my birthday)
You guys are probably asking yourself WHY MAY 20?!
Because I got suspended from school for 2 days. My parents are really getting mad at me for no reason... So yeah.

Keep putting up advice, because I have a few more questions ...

Alright, I've always had an interest in BBMGs, because my parents will not let me get a BB gun. I have taken apart many airsoft guns, and have modified these. But I wanna get serious, and I wanna build a gun that my friends will crap in their pants when they see it fire.

Alright, I will refresh ...

Hmm.. I will try dumpster diving in a local bike shop for a schrader valve ( or what maverik94 said ) And if I cant find one, do they carry them at a hardware store like home depot? If anyone has a local Home Depot, please let me know

Hey Spudfiles, where would I get a bike tire filler? Like you attach a bike pump to the filler and pump the air chamber up, and it maintains the air without the leaks?

Thanks,

Solvent welding is just putting pvc primer and pvc glue on a piece of pvc inside and out, and mashing them together for an airtight seal

Ok, what Im going to do is just start over, once I am satisfied because only a few leaks remain, and I could easily just start over.

Any Ideas on how to make a PVC chamber connect to the main gun by using a sprinkler valve? Never have seen this done, nor known anyone to do it. If someone could PM ...

Uh, Yea, Im pretty sure how to do that

Ok, how would I make a pvc chamber? Just take a 2 inch piece of pvc and put caps on it?

What should I use for my next project? Even though Im working on a Ball Valve cannon ( because this is my first EVER made cannon... )
Here are 3 questions.

1. Which one releases more air?
2. Which is more convenient for a trigger? I have made a trigger system for my cannon, and it is o.k
3. Is ...

Hey, what ammo r u using for that gun?

Ived heard that bottles can reach up to 120 psi. How much can a pvc chamber go up to?

O rly? Ill try that. But im using a small basket ball pump that runs inside the bottle through a vinyl tubing. I could use an air compressor from a bike, but I dunno where to get those.

Ok, heres how he did it... My friend made a potato cannon exactly like this.

The thing he turns is a mantle lighter, when you twist the knob, a large spark flys out of a wire.
He put hair spray, along with compressed air into the air chamber ( tank ) and since hair spray / deo spray is highly ...
