Screwcutting Book (Marcus Bowman)

"Screwcutting" is a guide to the theory and practice of threads and thread-making, whether that is threading a hole using hand tools or cutting a thread using a lathe.

The book covers: The major threadforms, such as metric, Whitworth and Unified threads, as well as the British Association (BA) and Model Engineering (ME and MME) series, the smaller metric and Unified threads, pipe threads, and specialist threads such as ACME, trapezoidal and RMS microscope threads

  • Techniques for making threads manually, as well as screwcutting in the lathe
  • Choosing materials, tools, feeds and speeds
  • Methods of measuring to ensure creation of threads of the right size and shape, to an appropriate tolerance to fit mating holes or fasteners
