Review: I have read this book cover-to-cover. It is hard to put down. As the author advises, the book is written from an industrial shop viewpoint, but many of the practices covered apply to the smaller scale hobby machinist. It is a jewel for novices as it explains many of the methods they have not been exposed to and clarifies many operations that might seem too difficult for the uninitiated. It is a must have for any hobby or commercial shop.
