This book takes a simple power tool, the router, and shows how to work with it by making and using jigs. The range of tasks that can be undertaken using these jigs is vast and the instructions in the book are clear and concise. The book is written in an easy going style so that it is enjoyable to read. However, this is a workshop manual and it the best one on my bookshelf on the use of the router. If you want to use the router to its full capabilities then this is the 'must have' manual.
