Epicycloidal Cutting Frame
Scope and Content
Administrative / Biographical History
The ornamental turning of wood and ivory was a popular leisure occupation among the English aristocracy in the early nineteenth century. Modern lathes were developed in the early eighteenth century, and many improvements were made over the course of the century, most notably by the Holtzapffel firm. Complex cutting tools and accessories, such as the epicycloid cutting frame, enabled the carving of intricate patterns. The epicycloid frame consisted of one or more circular gears rotating around a fixed gear to generate complex shapes.
