I am making a small pneumatic,
I didn't mod my sprinkler valve and I didn't screw my air gauge and my schrader valve yet.
my chamber is made of 2" pipe, it is 1 foot long
my barrel is made of 1" pipe, it is 2 feet long
here is the pic :

I just finished my small cannon !!! this is AWESOME the punch of it is so big, I am very surprised for the size, it is powerful ! with the bike pump next to my cannon, I fill it with only 20 pump at 100 psi !

thats umm......100 divided by 20 = 5 PSI per pump. is it just me and his pump or is it that the majority of pumps are 5 PSI each pump?

neat cannon, 5PSI per pump eh? nice. my junkie cannon only gets 1PSI per pump due to its huge chamber. but still, my over under cannon packs a wallop. nice job!

nice job! does the coupling on the end of ur small launcher make it a little quieter? I'd like to do that with the coaxial paintball gun i'm working on rather than putting a goofy looking silencer on it.

I didn't try it without muzzle but i did the muzzle for the look only ...

I want to make that little one EXTREMELY BADLY....
I found it to be around $7 for the fittings
1 -2'' Cap
1 -2'' Coupling
1 -2'' by 1'' threaded bushing (Slip*FIPS)
2 -1'' Male Threaded 90 ebows (MIPS*Slip)
1 -1'' Male Adapter
$10 for Valve (not including mod)
$6.31 for 10' x 2''
$3.08 for 10' x 1''
about $5 for the Shrader(sp?) valve [tire valve]
Thats about $32 without tax....
