Here it is 
It is currently in cure but I tested it with 20 psi, The piston seal perfect !
The chamber is 4" and 4 feet long, the barrel is 2" and 6 feet long. my piston is a 3" endcap.
here are the pics :
Edit :
I tryed it. dude it kicks ass !!!!
I shot a PVC dart at 1.1 km and I blow 2 cement beam with a 1" bolt with 2" washer.
I just did a very nice paintjob ! The stand has been done very quickly this is why it is a bit badely done ...

I couldn't tell from the pic. What's the gasket material. I'm prototyping a coaxial with 1.25" barrel, 1.5" chamber. A 1" endcap fitns but I haven't found the right gasket material and I get slow leaks just over 20 psi. |

| I see you figured out your bushing dilemma. Did that Spudtech thread help at all or was it all just a huge misunderstanding? |

what do launch? big taters? i'd hate to make a mess inside that nice gun though. maybe those large bouncy balls that are sold on spudtech, but u could prolly find em at a dollar store or something.
EDIT: i now see 4" male and female adapter so you can clean out the gun.
by the way that cannon is hard core

with a sabot, you can launch anything.
And I will make some PVC dart ...

The person who made the P.A.C. 5 on this site pretend that he shot a PVC dart 1276 meter  |

Do you need a sabot in a pneumatic to shoot water and flour and stuff?
What type of metal chamber is that?
I like guns that have like a 1" male out of the sprinkler and then a bushing to get it up to like 2" becaust then you can shoot golf balls while they're sheating on top of the 1" hole and they fire pretty good. |

Not if you put enough pressure in the chamber to seal the valve first, and if you're using a sprinkler valve you don't even have to do that. |
