Why put a copper barrel on it? when you could have put a PVC one for a total of about 2$
that would be one way to save money.
Add me on MSN to chat about whatever!

Becuase copper looks cooler?
Also, I like the ID of 1/2" type M copper. It's a perfect fit for marbles, and other things...

Ah you used your bottle adapter thing.
Sprinkler valve pilot looks neat.
Do you see vapor forming in the chamber when you fire it?

I've only shot it with the chamber sleeve off a handful of times, but I see it sometimes when it's sunny out.

Do you have deposit bottles (PET) where you live? Where I live nearly all drinks are in these bottles, designed for multiple use out of pretty thick plastic. Once I pushed one to over 200psi without deforming itself (only for testing).

You should add a pvc chamber so you can pressurize to higher pressures without blowing yourself up.

hes quite an experienced spudder so i think he is not foolish enough to take the pressure too high and he probably already knows that its stupid to take one near or over 100 psi. plus this isnt a serious cannon its just something he felt the urge to create.

As Mateo said, I didn't take this cannon past around 70-80 PSI. I've since scrapped it, though, so you don't have to worry too much...

Easy answer to that one. Cheap, simple to get hold of, ready made.
It's not good as far as durability or strength of course, but it is easy.
Does that thing kinda look like a big cat to you?
