In this book, the author has dealt with the usual faults likely to develop in each type of movement in a clock's general use, from the lordly grandfather to the humble alarm. All the tools and equipment are described and illustrated, together with the ways of using them. The craftsman's most important and valuable tools of all—his skillful fingers—are shown in use in the clearest manner. Over 400 line drawings have been specially made from parts under working conditions.
