Workshop Practice Series: No. 37 Dividing
Workshop Practice Series: This is a good series of books covering most aspects of engineering practice, written by well known names in the model engineering world. Faced with the prospect of machining a gear or gears for a project, many model engineers will be discouraged and will turn elsewhere for their next model. This need not be so, for the principles underlying gear cutting and many other aspects of engineering where an accurate division of circles is required 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 a semi-universal dividing head and a rotary table. The mathematical aspects of dividing are also covered but at a level that will be understood easily by a model engineer. Dividing equipment is relatively expensive, so two fully-detailed designs are included for dividing heads: a basic unit and the equivalent of a commercial semi-universal head. Author Harold Hall has established his reputation as a mentor to tyro engineers through the pages of Model Engineers' Workshop of which he was the editor for a number of years and through his other two books in this series.
