Non-Circular Gear Trains: a survey of a few designs using gears with some interesting shapes that can produce variations in rotation speeds, including two oblong gears, a triangle-square-oval train, two logarithmic spiral gears, and a four squircle gear set. A small sample of the infinite possible shape combinations and arrangements of non-circular gear sets. With thanks to @jeux.efce for sending me these wonderful laser cut gears and mounts. ➡️ Follow the link in my profile for info on where to
