Elastic-powered mp5 that fired some of the time. My first attempt at a gun that fires bullets, not just elastic bands.
About this creation
I had an idea that I could use my four rotating prongs method as well as a bullet, and that if a bullet were placed in the barrel and the elastic band were allowed to go through a very small space so that it hit the bullet roughly in the middle, I could make a gun that had far greater range than any I'd made before. I tested the theory and it seemed to work so I set about building an mp5 - a strange choice for a single-shot weapon but I wanted something fairly small but not as small as a pistol. It ended up having just two prongs for the firing mechanism because it was easier to fit a trigger onto two. It worked some of the time. However, for some reason a lot of the time the elastic band didn't seem to make contact with the bullet. I still don't know how that was possible.
I've been inundated with requests for instructions recently. Sorry, but not only do I not have time to make instructions, but also the models have usually been dismantled by the time people ask.
that is like the easiest way to make a fire mech. its just one ruber band that is attached to the front and when you pull the trigger the rubber band fires with the bullet but when it gets out of the barrel it is held by a hook or something. its the perfect mech for a beginer but not for you.
"You'll shoot your eye out, kid."
But seriously, this is quite realistic... actually almost disturbingly realistic. The retractable stock is a nice detail. Keep working on the mechanism, I'm sure you'll get it at some point. For me, it helps to CAD things like this up sometimes.
