I've grown accustomed to the differences in vocabulary, but others may need a translator. It's worth it, though. Nowhere else will you find all this information about shapers. After a quick introduction, the book gets directly into cutterhead design and grinding. This material is presented apparently in hopes that understanding the theory of cutting heads will lead to better understanding of how to operate the machine in terms of both results and safety.
Many pages are devoted to safety considerations and jigs.
Indeed, the jigs and templates collected here are adaptable to any shaper and are the high points of the book. If you have a shaper, you need this book.
