Well. I managed to get a bit more information out of the builder. Enough to confirm at least one of my suspicions. The trigger is pneumatic. I had thought this to be the case. If you pause the video at the side view you can see a hard plumbed air line pointing toward the trigger. The loading mechanism is a rotary breech- a modified ball valve. A rubber 0-ring retains the paintballs in the 'receiver' until the device is fired. The 'mist' seen in the video is indeed broken paint, not vapor. I'll provide this information with the same caution that the builder provided me with. CO2 will readily overpressurize PVC- A variety of safety precautions should be taken. Here's a challenge. Come up with a ball retainer that allows faster loading while effectively preventing balls from rolling out the barrel. And still allows the device to be discharged without breaking them all. I'm thinking something along the line of that rubber gasket that covers a garbage disposal- modified a bit. That and a positively HUGE ball valve for the breech. And an ammo box from one of the Tippmann A5's - huge bottom opening on that- The device would load with a quick back and forth flip of the ball valve. Wisdom would seem to dictate a kill switch that would prevent firing if the ball valve where in the wrong position. Double regulated CO2, an expansion chamber, sprinkler solenoid valve, safety poppit. Another crazy alternate idea. Using a modified ball valve as a breech loading system for a 'U' style pneumatic cannon. Would allow you to breech load Nerfs. Large ball valve with third port drilled in one side. Solenoid attaches here. Third port in 'ball' serves as air passage when valve is in firing position. Sorry using the 'Net as my brainstorming notebook again.
