Building the New Shay

£45.65

In this book, which he says will be his last full construction project description, Koza comes fill-circle, returning to his first locomotive type - the Shay geared locomotive. However this design is based on a much later design of Shay, dating from the 1920s, and is both slightly larger than the first design, but includes the improvements which were brought in during the 30 or so years since the previous prototype was built. If it is possible, this book is even more detailed than the earlier ones, and it also includes extra chapters on building the design in 71?4” or 71?2” gauges, the safety of copper boilers, safety valves, tube joints, O-rings for live steam use, and making small hexagonal screws. 326 pages in all, including a number of fold out ones.
