Books by A L Valentine

"Screw Thread Cutting" is a vintage guide to "threading", which refers to the process of creating screw threads. More screw threads are produced each year than any other machine component, and there are many methods of creating threads, including subtractive methods (cutting and grinding); deformative or transformative methods (rolling and forming; moulding and casting), and additive methods (such as 3D printing). This volume focuses on subtracting and transformative methods, making it a useful reference guide for those with an interest in traditional methods of making screws. Contents include: "Change Gears for Thread Cutting, by Erik Oberg", "Kinks and Suggestions in Thread Cutting", and "Tables and Formulas for Making Thread Tools, by A. L. Valentine, Erik Oberg, and Jos. M. Stabel". 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.
