As of June, there is a new book by Rodney Frost! This is the man who brought us Making Mad Toys & Mechanical Marvels in Wood as well as Whacky Toys, Whirligigs & Whatchamacallits, and Creative Kinetics: Making Mechanical Marvels in Wood.
As with all of Rodney Frost's books, this one is full of wonderful mechanical toy projects, solid advice on how to make them, step-by-step instructions, and large diagrams of the projects. The author -- known for his clever designs and charming folk aesthetics -- covers how to create whirligigs, traditional folk toys with interesting variations, and some unusual new kinetic creations. There are full-size patterns for 19 projects in total.
Rodney Frost's books are among the most useful for those interested in learning to build their own kinetic creations, whirligigs, and automata out of wood.
