Elementary Machine Shop Practice 1920 PDF Download

Excerpt from Elementary Machine Shop Practice The instructions given in this book should meet the requirements of beginners in general machine shop practice. The main object is to reduce as much as possible the time required to bring a student with no previous shop experience to the point where he is able to do some real work. The instructions given refer mainly to the cutting of metal, since this usually gives the most trouble to beginners. Little attempt has been made to describe the mechanism of the different machines because it varies so much with the type and make and is besides easily understood by the average student. To obtain the best results with this book the following procedure is suggested. In most cases it can be carried out without seriously interfering with the previously established work of the school: 1. The instructor should give practical demonstrations for the different exercises and actually perform those operations which he considers necessary. 2. The student should study the instructions given herein during his leisure time before and after the demonstration. 3. Each student should have a book for use in the shop so that it may be consulted whenever necessary. This will help to develop initiative. 4. A certain amount of time should be allowed to complete the work. This should be enough to enable the average student to finish on time. Many thanks are due to H. P. Miller, Jr., for his helpful assistance in the preparation of this book and to the following manufacturers for the half-tone illustrations: Smith & Mills Co., Sibley Machine Co., and the Cincinnati Milling Machine Co.
