thank you very much everyone, i had only built co2 cartridge cannons before, and was not thinking fully.
i have added more piping to act as the pressure chamber.
i have added a palmers sideline reg so act as a saftey for the tank just in case orings blow or whatever.
the safety relief valve is in the mail
and i got a bit ahead of myself and painted it.
currently it dry fires, but i have no nerf vortex rockets and my tank just ran out of air. i will try a paint load this sunday and come back with results.
