This early work by E. J. H. Jones is both expensive and hard to find in its first edition. Its 334 pages contain a wealth of information on jig and tool design including chapters on materials, gauges, grinding wheels, all accompanied with detailed technical drawings. This is a fascinating read for anyone interested in the intricacies of tooling and their historical methods of production. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
