4. Machine Gun

This is a nice complex LEGO machine gun.
“This is the best view of the mechanism. The crank is turned clockwise. This causes the large gear on the left to turn counterclockwise, and the small pinion engaged with the rack on the bolt to also turn counterclockwise. The pinion pushes the bolt back, stretching the rubber band.
The gun is fired by the lever on the very left ‘falling’ into one of the gaps between the little rivet-like legos stuck in the gear (there’s two positions around the circumference without a piece in them). When the lever is able to fall back, it pulls the lever on the front back, and disengages the pinion that pulls the rack. The rack is then rapidly pulled back by the rubber band, ejecting the projectile out the back on the left. ”

Hi Guys,
You will have to email the creator if you need more details (links are beside the pictures). For the first one I could not find any more details. By the way if you come across more details please let me know and I will add it.

im working on the instructions for something like number 3 its pretty simple
August 17th, 2006
I made one a lot like number one. I didn’t document instructions or anything, but i made an LDraw model. That way you can take it apart brick by brick to see the inner workings and probably build one.

I just finished a LEGO mindstorms NXT rubberband launcher . Too bad it can only shoot 2 rubberbands compared to Sebastian Dick’s Ultimate Rubberband Gun thing, which can shoot approximately 64 shots…

Dude, that lego crossbow is neat. I like how the color fits the theme of the gun. Too bad there are no other pictures with different point of views.
