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 book describes the many varied materials used by model engineers in their workshops such as iron and steel, non-ferrous metals including aluminium, brass and copper, hard and soft woods and a number of engineering and other plastics. It also contains details about abrasives, adhesives, bearing materials, ceramics and refractory materials, coatings, electroplating solutions, fuels, gases, lubricants, pickles, polishing materials, sealants and solders. It provides an easy reference for those seeking the right material for the task or an item specified on plan. Packed full of useful information, the book is aimed at those who build model locomotives, traction, boat and stationary steam engines, oil, diesel, glow and petrol engines, gas turbines, artillery pieces, farming appliances, carriages and other road vehicles as well as those who make clocks and workshop tools. It is also directed at those working with full-size machinery, such as vintage cars, motor and pedal cycles, traction engines and railway locomotives.

Every working model includes bearings, often a large number of them. This practical book describes the wide and diverse range of bearings found in the large variety of different types of models built in home workshops. It reviews the choice of bearings materials, the type of bearing to use for each particular application and highlights the differences between home-made and off-the-shelf bearings. It also considers the installation and care of bearings. Furthermore, it covers several full-size applications undertaken by model engineers, such as clock making and machine tool maintenance, which also call for some knowledge of bearings. It is now over forty years since Ian Bradley and Norman Hallows published the slim MAP volume Bearing Design and Fitting and much has changed in the bearing field since that date. This book provides a welcome addition to the Workshop Practice Series of books and will be welcomed by all model engineers, whatever their area of interest.
