Stan Bray provides all the information a ship modeler needs to power a model boat using a live steam power plant. A model engineer and author of wide experience, including editorship of the magazine "Model Engineers' Workshop," Bray offers detailed drawings for the construction of simple and advanced steam engines, boilers, and ancillary equipment. Many types of engines--from simple oscillating cylinder to piston and poppet valve--along with the application of radio control to the management of the boiler and engine are covered. Given the huge growth in interest in live steam powered model boats in recent years and the lack of practical details available, the plans and information included in this book will be welcomed by modelers everywhere.
