MECHANICAL AUTOMATA FOR BEGINNERS: A Practical Handbook for Building Cam-Driven Moving Figures Hardcover – March 8, 2026

This handbook walks through the process of designing and building hand-powered mechanical automata — wooden figures that move through systems of cams, cranks, levers, and linkages. The book begins with the foundational principles of mechanical motion, covering how rotating input is converted into the linear, oscillating, and intermittent outputs that animate a figure. From there it examines cam profiles in depth: eccentric cams, lobed and pear cams, snail and drop cams, heart cams, and multi-lobed configurations, with attention to the specific quality of motion each profile produces and practical guidance on laying out and cutting each type by hand.Follower systems are covered in equal detail, including contact tip types, guide arrangements, lever followers, and return mechanisms. Subsequent chapters address cranks and linkages, including four-bar linkages, bell cranks, parallel linkages, and the Scotch yoke, along with methods for coordinating multiple cams through timing diagrams and phase relationships. Frame and box construction is covered from a precision standpoint, with detailed guidance on bearing hole layout, shaft fitting, guide plate construction, and the full assembly sequence.The central project of the book is a three-cam owl automaton with a turning head, rising wing, and snapping beak, described in complete step-by-step detail including materials list, cutting list, cam layout instructions, figure carving guidance, and adjustment procedure. The final chapter covers mechanism refinement, advanced figure finishing, original design methodology, and the development of multi-axis and compound-figure compositions.Projects are designed for hobbyists working primarily with hand tools. Suitable for woodworkers, makers, and anyone drawn to kinetic sculpture, mechanical toys, and the tradition of folk automata. Interior illustrations are reproduced in black and white. Read more
