New dividing heads explained - book, milling, lathe


New copy of this excellent book.
Dividing by Harold Hall explains how radial work on a metalworking lathe, such as the cutting of gear wheels or the drilling of holes on a set radius, calls for a method of precisely spacing the cuts. The principles underlying this aspect of engineering are explained in depth in this book.
It covers the subject of Dividing, dealing with the many methods that can be adopted from simple applications without specialised equipment to the use of semi-universal dividing heads and rotary tables. The mathematical aspects are also covered and includes useful charts.
104 pages illustrated with many photos, charts and drawings.
