Books in the Crowood Metalworking Guides series

Explains the various workholding options that are available to the metalworker, together with the principles behind them. This book explains the importance of precision in holding work in place and also the importance of tools and machines being held securely, so that the machinist may avoid damage to the machine and to the work being undertaken.

With step-by-step instructions and photography throughout, this book explains dividing with the 'coordinate method' and using the lathe; dividing with gears and dividing plates; using the dividing head, the rotary table and the spin indexer; electronic dividing methods; and a range of case studies to show application of practical techniques.

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 details of 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 are also covered. As well as covering the basics of screwcutting, this book examines higher-level and advanced techniques, using case studies to demonstrate what can be achieved - fine, accurate and well-finished work.

Aimed specifically at the engineer for use in the workshop, this book is intended to take away as much as possible of the mathematics and mystique from calculating gear ratios. 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. Heat Treatment is a practical guide to this valuable range of workshop techniques and how to employ them safely and effectively. Featuring step-by-step photography throughout, this book covers metals and their properties; building a heat treatment oven for the home workshop; case hardening, flame hardening and tempering and finally, decorative finishes with colour case hardening, oil blacking and enamelling.

Computer-aided design (CAD) technology is essential for modern design and manufacture in the workshop. Whether you are new to using CAD or ready to try more advanced software, this title gives a thorough introduction to the technology and how to greatly enhance design and manufacture in the workshop.

Designing and building a miniature aero-engine is an exciting and rewarding task. 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.

This book describes how to make two vertical and two horizontal copper boilers with a capacity of less than three-bar litres. All four boilers are heated with liquid petroleum gas (LPG) contained in small refillable or disposable tanks. With over 285 colour photographs and diagrams, it includes the tools and equipment required, together with important safety considerations; how to work the various materials to make the necessary parts; step-by-step instructions on the technique of silver solder; the testing regime; a review of various sizes and shapes of gas burners and how to connect them; instructions for building replacements for the well-known Verto boiler, a vertical boat boiler, a portable-engine boiler and a Cornish boiler with Galloway tubes. Finally, there is guidance on the efficient operation and essential maintenance of steam boilers and safety calculations and a list of useful contacts.

Joining metals is a fundamental process used in all aspects of modern life. It is vital wherever metals are used, which is just about everywhere. Small or large, simple or complex ΓÇô no mode of transport or method of construction would be possible without the sound understanding of its theory and practice. Written for the home metalworker or model engineer, this book discusses the various methods of joining metals, including strength, testing and applications, and includes useful lessons from historical failures including the sinking of the Titanic, the Flixborough explosion, the capsize of the Alexander L. Keilland offshore platform, the Hyatt Hotel elevated walkway collapse and the Markham Colliery lift bolt failure. With over 100 diagrams and over 200 photographs, this book examines: Mechanical joining: bolting, riveting, clamping - Metallurgical joining: welding, brazing, soldering - Chemical joining: bonding difficult metals - Strength of joints: choice and analysis - Failure of metals and joints: stress, fatigue, corrosion - Design: use of theory and codes to avoid failure, and finally - Testing of metals and joints: destructive and non-destructive (NDT).
