ORBITAL DRAWING MACHINE

By Malcolm Green

Malcolm Green’s orbital drawing machine was a popular exhibit at a Midlands Model Engineering Exhibition. Pendulum drawing instruments have always been popular subjects for model engineers wanting a ‘different’ project. The oscillating pendulum employs several principles such as the force of gravity, momentum, inertia and entropy to create unique original artworks. Drawing machines include the Two Pendulum Harmonograph, Twin-elliptic Pendulum and Lissajous Figure Drawing Machine.
