Gears in one form or another are a part of most mechanisms, but they are by no means as simple as they may appear. This book explains simply, clearly and comprehensively the underlying theory involved and, in its second part, how to cut gears on a lathe or milling machine. Explanations and reasons for all conventional types of gears are clearly set out in this book together with useful tables and machinery techniques to form an invaluable reference work for anyone dealing with machinery. It covers all the questions raised by enthusiasts who have watched the author demonstrating gear-cutting techniques at exhibitions throughout Britain, where his advice on engineering matters has been constantly sought.

Although much of model engineering work is a matter of making one part to fit another and thus may obviate the need for the sophisticated means of measuring often called for in production engineering, the accuracy of a finished job begins with the exactness of the initial making out and continues with the accuracy of measurements made during the progress of the work. How to use measuring equipment and how to mark out work - not always the simple matter it might at first seem - are essential skills for any engineer and the purpose of this book is to show how they may be acquired and employed.
