This vintage book contains a complete guide to horology. Horology is the science of measuring time and constructing timepieces. This volume contains information on all aspects ranging from basic principles to oiling, cleaning, adjusting, and much more. Written in simple language and profusely illustrated, "A Practical Course in Horology" will be of considerable utility to novices and apprentices. Contents include: "General Principles", "Wheel Work", "Gearing", "The Lever Escapement", "The Controlling Mechanism", "Practical Repairing", "Train Problems", "Jeweling", "Making a Balance Staff", "Pivoting", "Fitting Balance Springs", "Escapement Adjusting", "Cleaning and Oiling", "Preliminary Notes on Adjusting", et cetera. Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern edition complete with a specially commissioned new introduction on the history of clocks and watches.
