Wanting to go out with a bang Answered
Alright, I'm sure you guys get the message, I don't build much lately. I think I might stash away the K'nex soon (I'll still stick around) but I feel bleh that I haven't actually posted anything in forever. I was going to get more images of the UMP-45 but I ended up mutating it into a non functioning modelish gun while I was bored and it'd take work to regut it so hopefully someone figures it out from the two pictures I posted. It's really not that hard.
Anyways, to the point. I still have that idea floating in my head from over a year ago that no one has been able to help me with yet. Basically, it's a fully automatic gun that doesn't require a motor, and it'd get decent range. The concept is pretty much to modify an RBG type gun to work with a piston system like the ones in modern firearms. It should have a controllable RoF then. The problem is that I still need a good RBG mech! It's funny how tricky it turned out to be. I need a cog/gear and trigger system that takes little effort to operate. This means that you'll need to somehow minimize the friction between the trigger and whatever is holding the rubber bands. If it's sensitive enough, the rest should be simple. But grr people keep leaving and I need someone who can make such a mech to MAKE IT ALREADY! I've tried so many times myself and failed but I'll give it another shot. It's essential before I can move on to the rest of the design.
