Moving along on the calendar mech. Here are four wheels: The notched calendar wheel and it’s accompanying 48 tooth gear, the shark-toothed wheel that works with a click to advance the days, and a v-notched wheel that meshes with the shark-toothed wheel, and will be at the center of the dial.
The calendar wheel has varying depths of notches depending on the corresponding month. They govern how much amplitude the great lever will have. The amplitude of the great lever determines how many days it grabs at the end of the month. It makes sense when you see it in action. There will be lots of videos once all these parts are working together in a test-frame. It’ll be easier to explain then.
Lots of things to make. More soon!
