Stan Bray introduces the fascinating world of horology to the complete beginner. This book explains the terminology of the clockmaker and provides general details of clock construction including layout of wheels and escarpments, a number of the latter being described. Making of wheels, pinions, escarpments, plates, pendulums, weights, cases, hands and faces is described. The necessary tools and equipment are described with details of how to make specialized items and choice of most suitable materials for their construction.

The book describes and illustrates the complete repair of the movement, including time and strike functions, and where applicable, dial, hands, and case. Eighteen American striking clocks, one time-only wall clock with date function, and one electromechanical clock are included.

Book 8 Ingraham, New Haven & Sessions covers clock movement repairs to the products of three major U.S. manufacturers from the late 19th and early 20th centuries. There is also a chapter on several other makers who produced fewer clocks or are less well known today. Chapter 1 Ingraham features the editor's favorite American brand. The movements were often fitted with the half-deadbeat strip pallet escapement featured in the chapter. Another article traces the changes made to the Ingraham movement from the 1880's through the 1920's. Other features describe repairs to the main wheel assembly and other parts. Chapter 2 New Haven covers a variety of movements, including a round strike movement, a round chime movement, and a heavy wall timepiece. There is also coverage of the Willcock Patent chime mechanism manufactured and sold by the company. Chapter 3 Sessions details the output of this maker between 1902 and the end of their pendulum clock production, during World War II. The common mantel clock movement is covered, in addition to a Sessions two-train chime movement designed in the 1930's. Chapter 4 Other American Makers presents the Newsletter articles on clocks by E.N. Welch, Welch, Spring & Co., several OG clock manufacturers, and the makers of calendar mechanisms.
