On the Wire

摘要

As well as containing a wealth of technical information of different types of screw threads, the book covers both manual and machine threading in great detail. Screwcutting in the lathe using changewheels is addressed in detail, providing a useful guide to a subject that is the cause of much head-scratching in our workshops. The book also addresses the issue of measuring threads. A particularly useful aspect of the book is that it addresses the appropriate tolerances for mating screw threads. Hopefully, this information will provide some solace to those who despair that their lathe cannot cut exact metric or imperial threads to the nearest micron, as working to the required tolerance is rather less demanding. Written by regular MEW contributor, Marcus Bowman, the book is his third for Crowood. It is presented in his usual clear style with many crisp images, clear diagrams and a number of practical examples of what can be achieved using the methods described.
