The Adjustable Spanner is the product of thirty years' collecting and original research, fired by Ron Geesin's acquisition of the SLIK adjustable spanner that hung in his father's garage. At the core of this book is a concise history of this much-maligned tool. Serious and comical observations parallel its chequered life, from its bent beginnings in the blacksmith's shop to over-designed and lovingly engineered treasures from the small Birmingham machinist. Around this core are discussions and findings about components and construction on the practical side, and patents, registered designs and trade marks on the design protection side. Emerging from history, we take a closer look at uses and especially abuses, immerse ourselves in an analysis of types and styles, and dive deeply into the histories of the inventors and makers. You will be amazed at the engineering diversity required to produce these most fanciful but essential supports to the Industrial Revolution. This entertaining account is the result of the author's findings, stemming from his collecting over 3,000 examples and will be of particular interest to engineers, those concerned with industrial history and collectors of hand tools. Superbly illustrated with around 300 colour photographs.

'A typically Mayesque celebration of classic engineering ... May is extraordinarily good at explaining what a carburettor is or outlining how a governor works... It's charming, transfixing and surprisingly intimate...It might be the best thing he's ever done.' - Guardian [review of BBC4 TV series] 'Reassembly is merely a form of therapy; something that stimulates a part of my brain that is left wanting in my daily life. When I rebuild a bicycle, I re-order my head. So might you... I'm delighted that you will be holding in your hands a book about putting things back together. It's a subject that fascinates me but which I assumed was a lonely passion that I would take to the grave, unconsummated by the normal channels of human interaction. Welcome! You and I, we are not alone, and our screwdrivers are our flashing Excaliburs as we sally forth to make small parts of the fragmented world whole again.' As in his hit BBC4 TV series, as well as learning the history of the objects, we get a history of the component parts. As James rebuilds an engine, he explains the cylinders, what they are, how they came about and what they do.

Provides apprentices with an easy way of finding specific information, and includes additional practical information on how to apply concepts in work-based contexts, as well as step-by-step advice on certain key techniques and procedures.
