With the intention of creating a more rugged and usefull mechanism, I went about drafting one up out of card-stock. The goal was to create a gear housing that contained the major orbital mechanisms to one plate that could then provide a clean, interference free surface on which to mount the armatures, all while transmiting any rotation to the neccesary peices. Also, as there are a few other mechanisms developed in the studio that require an exciter ring, I sought to make the mechanism modular so people could swap thier parts onto it [maybe I can rent it out, offset the cost of all this coffee....].
Keeping the weight down and the surfaces clean was a particular goal, so there is countersinking of axles, and significant material removed, while still keeping enough material to be durable. I also opened a small "window" into the gears - they're kind of neat and worth showing I believe. It gives an indication of the mechanism that concealed to keep the interference down.
Here are some pictures of the gear housing - its a good foundation on which to experiment with the next step - the armatures...
