Tubal Cain has achieved an international reputation both as a writer and modelmaker, but it is known less generally that in his previous career he was not only an engine designer of some note but also a teacher of engineering drawing. In this book he has amalgamated that experience with an appreciation of the difficulties often felt by model engineers when reading or making workshop drawings. He explains not only the 'rules' but also the reasons why they are important and, acting on the principle that one sketch is worth a thousand words, illustrates his points wherever possible. One of the merits of this book are the illustrations of conventions which are now out of date but are still to be found on many of the archive plans and drawings needed by the model engineer. This book will also serve as an aide-memoire to the professional engineer whose drawing-office days are over. This revised edition features the author's classic text with completely new illustrations and technical drawings, specially created for this purpose.
