This practical, instructional book describes the construction of a model of the Lampitt portable steam engine, which dates back to 1862, and which provided rotative power to drive threshing machines, circular saws, feed mills and other farm machinery. The construction of every component is described in precise detail and the text is supported by many helpful step-by-step photographs. In addition, useful advice is provided about obtaining materials and about the tools that are required to equip a model-engineering workshop. Accordingly, the information provided in this fascinating book will enable the reader to construct not only the Lampitt engine but also many other engineering models in the future. When the reader has finished building 'the Lampitt' he will, in effect, have completed an engineering apprenticeship, and will have a model engine of which he can be proud and which fully reveals the skills that he has learned. Fully illustrated with 142 step-by-step colour photographs.

The portable steam engine is closely related to the traction engine but is not self-moving, requiring to be towed. It was designed to drive machinery such as threshing machines, saws and pumps. Less attention has been paid to portables than their industrial significance warrants and this book gives an overall picture of their history and development, dealing with portables at work and in preservation. Technical features are examined in some detail, especially where portable engine practice differed from that of tractions. The introduction of portable engines into agriculture was a major advance not readily appreciated in these days of diesel and electric power. Their use spread into the forestry, construction and manufacturing industries. Portables were still being made after traction engine building had ceased and the author describes some old working machines.

The 19th century was the great age of steam. This book traces the history and development of the agricultural use of steam power from the 19th century to the end of the Second World War and considers how it was actually used.
