Building the Shay


The author’s homeis a flat where hobby space is limited, which influenced his choice of gauge and prototype - a Shay consists of a number of small sub-assemblies, with the boiler being the largest individual item. Kozo also wanted a prototype that could be built without castings and everything on this engine is fabricated, or turned from the solid. The drawings are very detailed, but what sets this book apart are the instructions on how to build individual parts, often using a series of drawings to illustrate sequence etc. The main drawings are metric. 194 pages. Drawings, numerous photos of set ups, and numerous sketches.

The photos show a 5" gauge version of Kozo's Shay on the Hurworth track of the South Durham Society of Model Engineers. Construction of this to chassis stage had been done by Mr. Jack Parish, but the engine was completed by Mr. W. McHugh, who is seen driving the engine on its first outing, when it ran well. Our thanks to Mr. McHugh for the photographs.

Whilst the original design is for 3 1/2" gauge, the book contains scaling aids and additional drawings so it may also be built in 5" and 7 1/4" gauges.
