The awesome automata artist Dug North does a quarterly column, “Dug’s Automata Tips, Techniques and Tricks,” on the Cabaret Mechanical Theater website. His latest installment outlines two different methods for making paper patterns for pinwheel gears. Pinwheel gears are relatively easy and fun to make and have various applications, such as above where they’re used in a bevel gear configuration to change the axis of rotation. Be sure to also check out Dug’s previous column on making wooden circles which can be used as the basis for these pinwheels.
