Metalworker's Data Book, number 42. ISBN 978 185486 253 2

This book contains a range of data of interest to the metalworker, both at the design stage of a project and its manufacture in the workshop. A major feature is that it contains a very wide range of data which otherwise would only available by reference to a number of sources or to very much more expensive publications.

Typically the book contains data relating to earlier subjects such as Whitworth thread forms but also details of the latest metric thread forms making it a valuable resource both to those involved in restoration and others working to present day standards.

At the present time the book is larger than other books in the Workshop Practice Series containing 217 pages being divided up into the following 31 sections.

Drills, Turning tools, End mills and Slot drills, Grinding wheels, Collets and tapers, Precision tooling, Spanners, Thread data, including tapping drill sizes, Screw thread forms, Screw cutting on the lathe, Worm Cutting, Gears, Belt Drives, Dividing, Presswork, Welding symbols, Mathematical formulae, T Slots and Dovetails, Electrical/Electronic components, Electrical formulas, Hardware dimensions, Material dimensions, Material specification, Miscellaneous data, Mathematical tables, Prime numbers, Conversion tables and factors, Further information, Glossary of engineering terms, Abbreviations, Index.

This is a very slightly edited version of the above W.P.S. book for the American market. See also Page 1
