This is but a simple, yet highly effective quick release trigger assembly that can be built by anyone with some very basic tools and supplies. I Also included some CAD photos for a more clear view.
Before we succeed we must at least fail one time. This video shows the trigger in operation with too low tension applied. As you can see, the plastic-on-metal combination has too much friction, I would rather suggest using metal, or any other hard surface material.
This video shows the simple way in witch this trigger operates, but as seen in the other video, there is a min tension required to overcome some friction.
