Cuckoo Castle

Description

We wanted our clock to have the element of fear and surprise.

The crank winds the drawbridge down, but instead of the dragon being present behind the draw bridge, it pops up out of the roof of the castle.

We used a linkage and pulleys to translate the rotational motion of the crank to make the dragon pop up.
