How to determine the psi in a tank when it joins with a larger tank that's empty?
One more question: my plan is to make the air tank just screw onto the gun. Will this still be airtight? Do I need a quick release valve instead of threaded pvc?
My plan is to make the larger reservoir but put a ball valve on the end where it connects to the rest of the gun. This is so I can screw it on and turn the valve.
