update ..
well i have sort of come stuck on suitable 'on-hand' materials for the pressure vessel. Also i need some brazin' done to my barrels.
There is 2 old fire extinguishers i could use but have the same issue with both... i have no way to connect them in their current state.. e.g need to drill and tap... I could go all cowboy on it's arse and heat some air hose and force it over the neck of the extinguisher, hose clamp it on, then to a push on barb fitting to the hose thus connecting to the gun but that would look like chit and not all that trust worthy.
The one i'd prefer to use is very light aluminium 1 kg tank(2.2lb) it has a nice long Al. neck fitting which would tap a nice thread in or out... if i had taps to do them the female thread on the neck is 1/4 inch but is a very fine thread where all the brass fittings I have are npt 'coarse thread'. I've been scavenging all day, pulling stuff apart trying to find a fit and come up with nuts.< and they don't fit either...lol
I have seen those creations/abominations where people use soda bottles as a vessel, i could do that.. but no thanks.
