Make365 - Wood Automaton Crank Design

When I first started toying with the idea of making an automaton this year, I drew some pictures in my notebook. This was one of the first images I drew to try to understand the idea of a crank and the circular disc that would cause motion in the automaton.

I probably should have jumped online and done some research instead. I didn't have to reinvent the wheel. But, then again, it allowed me to learn more via mistakes and poor decisions.
