MOC: Drawbridge Mechanism (Gate)

[noname]

For more information about the minifigs and for the story, click here.

My second castle MOC! I've used old "Expert Builder" gears that were found in the attic in this MOC. (These parts are 40 years old!)

There's a blue pin connected to the gear. When the gear spins clockwise, the pin reaches the "brake" and holds the bridge mid-air. This gear also spins the second gear counter-clockwise. The second gear is connected to an axle, and when the axle spins it lifts the whole bridge.

The heads of the towers are removable.

There's a wheel in one of the towers. It is connected to the gear with the pin. When the wheel is spun, it activates the whole mechanism.

The wheel was spun, so the pin reached the "brake".

The second tower.

It took few days to build, because I forgot I had these gears- I even tried to build it with a tractor's wheels , but there was not enough friction.

I've filmed the mechanism in action, but Youtube and Photobucket gave me an error message when I tried to upload it.

You may notice that in some pictures, the flags are connected to "poles" and in some pictures there are no poles, because I took some pictures in the evening, and in the morning I didn't find one pole, so I removed the second.

Your MOC is nice, but I really like those gears. Admittedly the blue color scheme may not be the best for castle, but the fact that those pieces are so OLD really hammers home the longevity of Lego blocks. Thanks for sharing this with us.

Nice use of those gears. I love the tower witht he control gear. Nice job.

This is clever, I remember seeing those gears in my old Lego League class.

I really like your mechanism for the drawbridge 'noname' - very simple yet very clever !

Great designing and I'm a conformist! !
