It also includes Myford and other types of lathes; approximations and alternatives; errors and their significance and the non-gearbox mini-lathe.

Using sharp tools is one of life's great joys. A sharp tool feels right; the job seems that much easier; and the quality of the cut usually means there is less work to do to produce a finished surface on the object. This book provides an understanding of what is involved in sharpening common workshop tools. With over 580 colour photographs and illustrations it covers sharpening techniques for the most commonly used tools - scissors, shears, knives, lathe tools and drills, screwdrivers, chisels and punches, along with the more specialist gravers and scrapers. Advice on types of abrasives, grades, grits and mesh sizes is given. It describes what happens during the sharpening process and provides practical guidance on using sharpening stones and grinding wheels on a bench grinder. Provides essential maintenance instructions such as how to restore the surface of a flat stone and the face of the wheel on a bench grinder. Finally, it gives advice on bench grinders, and includes examples of the use of readily available tools and accessories such as vee blocks, toolposts, collet holders, protractors and gauges.

The techniques of casting are of crucial importance in our day-to-day lives, being used in the manufacture of diverse products ranging from dental implants and hip replacement joints, through bicycle frames and car engine parts, to the most exquisite items of sculpture and jewellery. Nevertheless, the prospect of casting can seem daunting to the home metalworker. Casting for the Home Workshop aims to demystify the craft and make it accessible to all. Topics covered include the history of casting; tools, materials and equipment; techniques; the home foundry and post-casting operations.

The ability to perform heat treatments in the home workshop can be a very useful asset, enabling you to make, repair and maintain tools, to anneal and normalize work-hardened metals, and even to create decorative finishes.

Whether a professional engineer or an amateur looking to build an engine to fly your model aeroplane, this book helps you guide through all the stages of designing and constructing an aero-engine in your workshop at home.

The cutting edges on engineering tools must lie at precise angles to ensure effective cutting, and sharpening must recreate the original geometry of each tool. This book provides an understanding of what is involved in sharpening typical lathe, milling, drilling and threading tools. With over 550 photographs and illustrations this new book covers sharpening techniques for the most commonly used engineering tools, screwdrivers and gravers, lathe, milling, reaming, drilling and threading cutters. It identifies the two principal types of workhead, and discusses the ways in which their geometry affects typical sharpening setups. It teaches how to use the three basic movements of swing, tilt and rotate to position a tool against a grinding wheel to ensure correct tool angles and sharp cutting edges. Contains useful tables for setting cutting and clearance angles and provides general advice on tool and cutter grinders, and includes examples of the use of workholders to suit a range of tools. Includes information on abrasive materials and the types and shapes of grinding wheel suitable for use on a tool and cutter grinder. Finally, it shows photos of accessories that can be made to simplify setups, including workheads, toolholders and fixtures used to hold circular saws, parting tools and dies, as well as an angle gauge to quickly set clearance angles on reamers and milling cutters.
