I was asked to design and build the gear and drive mechanism for a 6 foot clock. The clock had an hour and a minute hand and needed to move in both the clockwise and anti-clockwise direction. This was not a “realtime clock” and needed to move visibly fast.
I decided to use wood clock gears with a motor drive for the sake of simplicity. This build was definitely more out of my comfort zone than usual but proved to be a fun and educational experience. Part 1 goes over the design of the gears. Part 2 will cover the physical build and Part 3 the electrical design and final build.
