For a while, I was working on building a LEGO mechanical clock. Here are some of the results of that work:


The first one was the best working model. All it really needed was a longer and heavier pendulum, and a steady flow of force, provided by a weight or something. The escapement was inspired by that of another LEGO clock maker guy online.
The second one was my first try at it. It works surprisingly well, though it had to be at a slight angle for the pendulum to work correctly. The escapement on this was more like an actual escapement, but, as anyone who has tried making a LEGO clock before can tell you, it’s darn hard to make a ‘real’ escapement out of LEGO.
