Help with construction/materials of a firing chamber?

[stoj]

I'm in the process of building my first pneumatic, and I'm not too sure what to use for the firing chamber (using a qev piloted by a slide, fire extinguisher as the main tank)

Would these be too small?

(note obviously I'd remove the co2 inside them first)

(Looking to operate at 80-100psi, firing splatballs)

Or will aluminium pipes with end caps fitted be sufficient and safe to operate?

Yes, those are in fact too small, but If you're only operating at 80 to 100 PSI, the PVC will do just fine, but If you like the aluminum pipe more, go ahead! also, airsoft BB's don't require THAT much PSI in a game, unless you're using a BBMG.. Hope I helped!

Thanks heaps for that, I deterred from using PVC as the main tank also because of the risk at hand with rough wear and tear (dropping it, knocking it occasionally, etc; producing small cracks that exponentially increase).

I think I'll use whatever pipe is cheapest with suitable end caps.
