In this book, long-time model maker Stan Bray describes the construction of a range of uncomplicated miniature steam engines, for construction by the model engineer. Single-acting oscillator to more sophisticated twin-cylinder double-acting engines are described as well as the construction of a range of boilers. The final project brings together engine and boiler into a simple steam railway locomotive. Full drawings in both metric and imperial formats are included. Every project in this book can be completed with a minimum of workshop tools, and they are a perfect way into model engineering for the uninitiated, and the ideal relaxation for the more experienced engineer.
