Looks like there are reducers to all of the ports of the tee? If so that will hit your power.
Otherwise another great copper cannon! How ergonomic is it? I used the ball valves you're using and they were cack! leaked like a sieve!

Jonnyboy - the nicest thing for copper IMO, is polishing it then lacquering. Keeps that beautiful shine.

the chamber is 35mm then a Yorkshire 28 fitting was hammered into the 35mm pipe and lots of solder the piston sealing face is a piece of 22mm pipe and is the smallest part

it is quite nice to hold you get a nice recoil as well im thinking of fitting a 2kg 200bar extinguisher to it to store hpa and since its aluminum it will polish up nice aswell im also thinking about putting a long marble barrel on it

You sure it's rated to 200 bar? It's just that usually the aluminium fire extinguishers here are for powder and only rated to a few hundred PSI. Yours could be different though.

well not rated but stamped and dated 200bar test pressure and ime sure it has a good safety factor on top of that and i would only be using 100 bar if i can get another frige pump to charge it

Oh ok, yeah if it says 200bar, it can take 100bar (assuming itt's not damaged).
