More progress on the Early Bird model. I've ben working on the Early Bird as well as updating the mechanisms section of the website.
I've adapted one of my ratchet projects to fit on the side of the bird. Now that I see how it works (and that it works!) I'll be able to make it a more appropriate shape. It'll need a couple of stops on the body to limit rotation of the ratchet housing then I'll add a small handle of some type. To operate the model it'll be a case of moving the ratchet housing back and forth. Five teeth on the ratchet so five back-and-forths equals one full revolution on the cam.
On the other side of the model I've fitted a simple ratchet and pawl to stop the cam rotating backwards.
