How to: build a fully automatic PVC paintball gun - part 1: overveiw

Here is a diagram: The basic idea on how this works is; air comes and pushes a bolt forward, pushing a paintball along with it, once the bolt is all the way forward air is allowed to flow though the bolt and push the paintball out of the barrel. once the pressure drops a spring pushes the bolt back, clearing the way for another paintball to fall in to place. As the bolt is being pushed back it is also stopping more air from flowing out, this redirects more air in to the sprinkler valve causing it to seal up faster - with the help of a BB and another spring. In this video i attempt to show you how to modify an air cannon to work as a fully automatic paint ball gun. I mainly focus on the paintball loading mechanism, but i also explain what is needed to build the full thing. Background music was all downloaded from audionautiX (link below).
