On your recommendation and the comments by others in this thread I have bought 'the book'. To be honest, I too am just blown away by the hardback form, its actual size, and its contents of over 400 pages of extremely detailed engineering, machining, fixture holding, and techniques, with illustrations, of machining and preparation of simple and complex forms. Unfortunately, I will be away from my workshop for at least a year while working overseas, but this book will accompany me. From just the very few pages I have read, it is well worth while. Yes, I am trying to build a clock, and it is proving to be a rewarding but challenging assault on my limited skills. I have completed only the plates, the plate spacers and the dial so far of a Strutt Epicyclic.....the next phases will be the gear cutting, and I really want to read the book before hand .
