This volume contains a vintage guide to machine design and workshop practise, with this edition focusing on screw thread tools and gauges. A gauge or gage is a scientific or engineering device that is used to measure or to display certain dimensional information. A wide range of such tools exist which serve this function, ranging from simple pieces of material against which sizes can be measured to large and complex pieces of machinery. With helpful diagrams, useful measurement tables, and simple explanations, this volume would make for fantastic reference guide for engineers and handy addition to collections of allied literature. Contents include: "Screw Thread Systems, by Erik Oberg", "Making Thread Tools, by E. A. Johnson", "Tools for Accurate Thread Cutting, by Jos. M. Stabel", "Making Thread Gages, by. A. L. Monrad", "Measuring Screw Thread Diameters, by Walter Cantelo", etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork.
