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.

This book covers the materials needed to make ceramic burners and explains how to silver solder them. It discusses LPG and holding tanks, as well as connecting pipework and electronic and mechanical automatic gas-control systems to monitor the boiler pressure. In addition, there is advice on how to set up, install and operate each burner to provide optimum heating to the boiler. A summary of the Boiler Test Code Volume 3 that applies to home-made gas tanks is included, together with a list of useful suppliers with their contact details. This book provides all the information you need to build and operate: three burners, with one variant, for boilers with 42mm, 35mm and 28mm horizontal flues; two round burners for vertical boilers with fire boxes; two different sizes of rectangular burner, with one variant, for use in horizontal water-tube or pot boilers and finally, one small round and one tiny oblong burner for use in Mamod and Wilesco boilers. The burners described are straightforward to make and simple to use to heat the water in boilers that meet the 3 bar litre limit in the UK Boiler Test Code.

This second edition of Workshop Electrics has been completely revised and updated to bring it in line with the latest advances in technology and to fully conform with BS7671 (17th edition of wiring regulations). A quarter of the illustrations are also new. The book deals with electricity in the workshop and includes everything from fitting a 13amp plug to wiring up a new workshop building. Safety, a key issue is covered as well as inspection and testing. Starting with the planning necessary before electrical installation commences, the book then deals with the fusing, equipment, lighting, fixtures, fittings and wiring for 230-volt mains electricity. Further chapters cover outside workshops, three-phase supplies and a range of low-voltage equipment. Finally there is a glossary, a list of useful addresses and an index.

A comprehensive guide dealing in detail with every imaginable aspect associated with the design, modification and construction of radio-controlled sports model aircraft powered by internal combustion or electric motors. The text helps the modeller who has built one or two kit model aircraft to progress from simple modifications to the creation of unique designs. The author deals with basic materials, essential aerodynamic considerations, the various constructional methods, the wide range of model configurations and size as well as a broad choice of power plants. The book finishes with tips on drawing plans, getting them published and safely completing the early test flights.

A comprehensive guide to the use of plastics in the many and varied fields of modelling. This book describes the various types and forms of plastics and details their useful characteristics, strengths and weaknesses. It also explains how to source them, how to work with them when making models and examines their applications in each of the many and varied branches of modelling: flying model aircraft; rockets; model power boats, yachts and submarines; model cars; plastic kits; scratchbuilt models of aircraft, ships, spacecraft and cars; figures for aircraft, boats, cars, fantasy games, military modelling or railway layouts; buildings for dolls, railways or wargaming; railway locomotives and rolling stock (7.5 inch to N gauge); Model engineering models and tools; electronics. Well illustrated with informative line drawings, instructive photographs and amusing cartoons, the book is a mine of information which explains why you might choose, or prefer to substitute, plastics for the more commonly used materials such as wood and metal. Alex Weiss has first-hand experience both of working in many different areas of modelling and of using the majority of the materials described. He has packed a lifetime of working with plastics into this concise and practical book.

A complete and comprehensive guide to the popular hobby of radio controlled model aircraft, written with both the beginner and the experienced modeller in mind. It covers, in a logical order, every aspect from how to enter the hobby and choose the right model, engine and how to build a basic trainer model. It is full of useful information on materials and construction techniques. A significant part of the author's instruction deals with learning to fly. He covers both the essential and the advanced manoeuvres and aerobatics, and also more specialist areas such as electric flight, gliders, autogyros and helicopters, advanced models for aerobatics, pylon racing, ducted fan powered models and turbojets. Lavishly illustrated with amusing cartoons, detailed line drawings and informative photographs, the book examines every aspect of radio modelling in a simple and straightforward manner.
