Summary

Scenic effects involving rotating turntables, tracking stage wagons, and the vertical movement of curtains and painted drops have become common in both Broadway and Regional theatre productions. The machines that drive these effects range from small pneumatic cylinders pushing loads of a few pounds an inch or two, to 40 horsepower winches running multi-ton scenery at speeds 6 feet per second or more. Usually this machinery is designed by theatre technicians specifically for a particular show's effect. Compared to general industry, this design process is short, often only a few days long, it is done by one person, design teams are rare, and it is done in the absence of reference material specifically addressing the issues involved. The main goal of this book is to remedy this last situation. Mechanical Design for the Stage will be a reference for you that will: * provide the basic engineering formulas needed to predict the forces, torques, speeds, and power required by a given move * give a technician a design process to follow which will direct their work from general concepts to specific detail as a design evolves, and * show many examples of traditional stage machinery designs. The book's emphasis will be on following standard engineering design and construction practices, and developing machines that are functional, efficient to build, easily maintained, and safe to use. * provides the basic engineering formulas needed to predict the forces torques, speeds, and power required by a given move * describes the most common power transmission components used in stage machines: roller chain, cable drums, bearings, gear reducers, etc. * gives a technician a design process to follow which will direct their work from general concepts to specific detail as a design evolves * shows many examples of traditional stage machinery designs
