Hello, and thank you in advance. My friend is a glassblower, and I am a woodworker. He makes lovely ballerina pendants, and I had thought it would be nice to set one in a display that let the ballerina spin around. (point of contact being her pointed toe) I mulled the idea over long enough that it grew a bit too big for my engineering britches, but I am sure that there is an elegant solution and that the idea is feasible, hopefully I'm correct and you're feeling generous enough to enlighten me. Idea: A small circle of Maple within a larger circle of Walnut,(Maple off center approx 1/2 of radius of Walnut) the ballerina would be set off center in the Maple. The ballerina would spin clockwise, the maple would spin counterclockwise, and the walnut would spin clockwise. If I'm correct this will give the effect of a spotlight chasing the dancer around a dark stage. I feel like this can be done with gears and a single motor, perhaps I need three motors, perhaps you can point or shove me in the right direction.
