This vintage book contains a detailed treatise on the subject of steel, exploring in particular how it is selected, hardened, and annealed. "Annealing" refers to a hardening process whereby steel is heated above the re-crystallization temperature and subsequently cooled in a furnace, water, or oil. Tempering is a process that removes "stress" by heating steel below the re-crystallization temperature and then is cooling it in the air. This volume contains simple explanations and step-by-step instructions for these processes, making it ideal for novices or apprentices, as well as a handy reference guide for more experienced metalworkers. Contents include: "The Workman", "Steel", "Methods of Heating", "Heating Tool Steel", "Forging", "Hardening Baths", "The Lead Bath", "Cyanide of Potassium Bath", "Hardening Steel", "Drawing the Temper after Hardening". "Examples of Hardening", "Hardening Dies", "Forming Dies", "Ring Dies", "Screw Threading Dies", "Hardening Long Articles", 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 a specially-commissioned new introduction on metalwork.

Part of the "Machinery's Reference Series", this vintage book contains a complete guide to milling fixtures. A fixture refers to support or holding device that is used in manufacturing. Milling is the term used to describe the processes that uses a machine designed to cut or shape metal using a rotating tool. Written in clear, easy-to-understand language and profusely illustrated throughout, this volume is recommended for those with an interest in traditional methods of milling and manufacturing processes in general. Contents include: "Elementary Principles of Milling Fixtures, by E. R. Markham", "Provisions for Removing Chips", "Special Forms of Vise Jaws", "Cams or Eccentrics for Binding Vise Jaws", "Hardening Vise Jaws", "Regular Milling Fixtures", "Examples From Actual Experience", "Principles of Gang Fixtures", "Prevention of Springing Action Fixtures", 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.
