    I've been trying to design a mechanism in my head to drive the cutter. I've worked out that it would require a 3:1 gear ratio somewhere. The simplest I can thing of is to have a Reuleaux triangular shaft in a match square housing driven by a flexible shaft. The only problem is that it would only suit one size of cutter (and one size of hole).

    It seems like a good application for CNC machinery to drive the cutter through the required pattern - at least by using software, it could cut many different hole sizes.

    I wonder if the machine shown does more than one size of hole?

    Anyway, thanks for sharing, it is an impressive example of mathematics at work.

    Here's a mechanism, but I'd love to see the internals of the drill part above that appears to be just on a Morse taper that would fit an ordinary bench drill.
