Project One for Patrick Harrop's "Hacking Studio" begins with a drawing machine drawn and built out of paper. Two machines from Illich Artoblevski’s Mechanisms in Modern Engineering Design will be integrated into the project. I selected one mechanism that generates a fourth-degree curve and a "Hain Linkwork Tilting Crawler."
Today was spent figuring out how the fourth-degree curve generator might work and designing the gears that it requires. Using simple circle geometry, I constructed a set of gears with three elliptical lobes. They almost worked (and probably would work well if the gears could be constructed absolutely perfectly). The lobes mesh together well, but slight variations in the lobes cause the gears to lose contact with one another.
I constructed another set of more conventional gears that seem to work well (at least in millboard form). I'll try them in paper form tomorrow.
