How to Draw an Egg, the hard way.

The transformation from schematic to a operating mechanism is proving far more difficult than originally anticipated. The simple act of exploding the digram into its component parts introduces a whole new series of variables and issues. The most significant of these is the interference between the different parts - what "planes" each object is functioning on and how each peice may block or react to eachother. Closely tied to this is the issue of joinery, particulairy the dynamic joints such as sliders and points of rotation. My initial attempt was to simply build it as closely following the schematic as possible - almost a literal interpretation. This allowed me to investigate interference zones, and experiment with preliminary joint connections. It failed to work, and subsequent attempts and "tweaking" led to some creative applications of various four letter words. In addition to puncture wounds sustained from thumbtacks, three main issues emerged from this first iteration:
1. Interference points [obviously]
2. The critical nature of the 90 degree slider joint
3. Actuating both orbits at the same time was difficult and required another approach.
