so how about around 20mm steel pipe ie endcap and reducerish thing aswell as 20 bar ball valve and what ever barrel i can find as i douht a carbon fiber tent pole can hold back 200 odd psi!

either that or basically the same thing with larger bbs maybe the ones of the crank case :D

The barrel only needs to support pressure for a brief period of time so it can afford to be much weaker than your chamber, for example I've used electrical conduit as a barrel with 400 psi pneumatics with no problems.

PN18 means it's rated for 18 bar, which means you're safe with 250 psi. If you're sticking with a 3mm barrel though, I'd go for a long barrel and similarly long chamber if it's 20mm

Post a new thread as soon as you've sorted out plans for your modified idea.
