I designed and cut the next gear. It is a 12 sided gear. While I was designing it, I thought "What interesting slant can I do with the number '12'?" My first idea was "there are 12 months", so I could do something with seasons.
But then in a flash, it came to me...the Zodiac Signs! So I made a Zodiac Gear. Here it is:
You can see some of the details in the following pictures. Each tooth of the gear represents a different Zodiac Sign. You can symbols for each, as well as it's constellation.
In the center, there is a "sun".
