Second Note- I know I look pretty shaggy in the video. I had just finish building, hadn't shaved in a few days and was too exited to show off my gun to go make myself look better. Also, I apologize for fliping the bird. I lost my index finger in a table saw accident at work so I have to point with my middle finger.
These guns were custom built for this movie by John Bowring, a builder of weapons used in movies. If you've ever seen a movie gun that made you say "wow, that's cool..." , chances are that this guy built it. These are cam driven, 25 round, rotating drum, automatic shotguns. What this means (I'm pretty sure anyway) is that the trigger activates a motor, located at the top of the gun, which turns the drum. Behind the drum is a spring loaded firing-pin that strikes each shotgun shell as the drum turns. Firing rate is determined by the speed of the motors that turn the drums. The genius of these guns, besides how awesome they look, is the simplicity of the whole system. Our versions of these guns are, by comparison, much more complicated; but as you can see, very do-able and worth the time put in to building them.
It was both a blessing and curse that these guns were only onscreen for a few seconds. You only get a visual of the front half of the gun, so what's the back half supposed to look like....? Answer: Whatever I want it to look like, or more accurately, whatever I need it to look like. The most difficult part of this project was incorporating the automatic mechanism of the Nerf Vulcan into the body of the Nerf Firefly, kind of like Dr. Frankenstein's monster.
Here's a quick overview of what you will be doing to complete this project. We will be removing the automatic firing mechanism from the Nerf Vulcan. Redesigning the body of the Nerf Firefly to accommodate this mechanism. Building a trigger to activate it. Building a drum to house the ammo chain from the Vulcan. Finally, relocate and build a housing for the light that was in the Firefly. Simple, right?
Take your time with each step and focus on the details, making everything fit together smoothly, before moving on to the next step. I will say that having a 3D printer would have made building this gun much easier and more accurate, but I don't have one.
This project took me a while and, although the focus was not on making an exact copy, is very involved. It does require some electrical and mechanical know how. Being an unconventional build, some of the way things fit together will be up to your judgement. I will be guiding you through the process of constructing the pieces to the best of my ability and hopefully in the end, you will have a truly unique Nerf weapon.
