Dividing

The book "Dividing" by Harold Hall offers a comprehensive introduction to the techniques of dividing and precisely machining gears, which are crucial for model builders. Many modeling engineers may be deterred by the challenge of manufacturing gears, but this work demonstrates that the principles of gear cutting and accurate circle division are not only understandable but also achievable. The book covers various methods of dividing, ranging from simple applications without special equipment to the use of a semi-universal dividing head and a rotary table. The mathematical foundations are explained in a clear and accessible manner, making them easy for model builders to grasp. Additionally, the book includes two detailed construction guides for dividing heads, which are beneficial for both beginners and experienced model builders.
