Co Axial idea. *Update-Video*

I like it!

Is the pump cylinder being held by that little plastic latch though? Looks like it can fail easily, potentially dangerous.

got it all cleaned up and shes shooting very nicely indeed

How about a nice little video

Indeed it is being held in by only that tab of pvc pipe, however the force on the piston is quite small and i trust it entirely.
I have also experimented with tapping it off of the tab while at full pressure, the piston barely has enough force to overcome its own friction and only juuust reaches the end outer limits of its stroke.

The metal circle on the lower pvc sleeve is a high tensile pin, holding a solid machine grade aluminium plug inside the pipe, which holds the pump center and also retains it securely inside the tube.
