Springs into action

For any of this to make sense, you might want to read the previous post, "First One's the Hardest". As I wrote in that post, the natural laws of physics always win out. In this case, the raising eyebrow mechanics won't have a single spring between the two levers (as pictured in my blurry mind's eye). Oh, no. The levers will each have a spring attached to the side of the head. Because I'm using stationary cartoon eyes, there are no side-to-side eye mechanics to get in the way. With this configuration, the eyebrow levers and the rod-and-tube pulley have plenty of distance between them. Cords will be attached to the levers, draped over the pulley (above) and fall downward through the PVC pipe control post to a single trigger.
