This Informative Book: Stage Rigging Handbook is a must read. Because there been no handbook for the safe and care of stage rigging, knowledge of that craft has been passed on by work od mouth. Some of this information has been misleading, some even false. The author corrects many of those misconceptions that have infiltrated the oral tradition, providing sound and safe techniques for doing stage rigging.
A great guide to the process of safely setting up the technicals of a production. It teaches knots, the mathematics behind rigging systems, etc... Just a great guide for anyone who works in the field or wants to know more about the field. It's very easy to understand and explains the mathmatical concepts behind rigging in ways that anyone can grasp. I had not taken any math class beyond Algebra II and was able to do fairly well in my rigging class with this book (the concepts are mainly trigonometry from my understanding).
This was a solid beginning to modern-day stage rigging. I would certainly recommend it to students and beginners, people who are not confident in their rigging knowledge, people who need a review. Although there is not a lot of in-depth information about some systems and motors, I felt I had a solid handle on the basic forces and calculations needed to rig onstage, knots, ropes, and hardware. Thumbs up!
