A little more progress on the new mini automata I've been working on. I've added a a squirrel to the top of the tree trunk who's world is being rocked by the back rubbing of the bear. It is about 5/8' tall and his tail moves up and down in sync with e the bears rubbing. The mount in the photo on the right is 1" in diameter and fits down inside the top of the trunk so the mechanism is hidden. The brass pivot bar converts a 1/4" vertical movement to a 1/8" horizontal movement which moves the tail.
Meanwhile the bear is taking shape as shown below. He needs more shaping, a face, some ears, some fur and a mechanism to raise his arms up and down, so back to work!
Automata is a creative blend of my life interests , engineering, art and woodworking.
