Super Simple Gear Geometry

This June I’ll be teaching a summer camp class to 4th and 5th graders titled “Gears and Gravity.” In my proposal I claimed, “We will explore the history and science of time keeping (horology) by hands on experimentation with simple machines and then construct our own real working mechanical clocks from paper and wood.” Now I have to design said clock.

My first challenge is to design a gear train (“going train” in horology parlance) with the simplest possible tooth profile that is easy to cut out and error tolerant.

Did I mention that my class budget is $125?
