I bought this book because I plan to buy a jointer/planer. I am not a professional but, in spite of my somewhat low level, the book did not give me much useful information. It is mostly a collection of trivialities, such as instructions for making a stand in mdf board, or 1 1/2 pages with ridiculous instructions on how to remove a motor (disconnect wires, remove bolts, remove belt, remove pulley if necessary...). There is no useful info on combined jointers/planers. Flowcharts on choice of jointers/planers seem useless. I do not recommend this book to anyone. The chapter on jointers and planers in Duginske's book "Mastering Woodworking Machines" gives much more information in much less space.
