Query: Boy, was I disappointed!

I have to disagree with the reviewers who gave this book high marks. While Jim Richey is very knowledgeable, this book is a set of one-page clippings from various past magazines. The drawings are very basic, and there's not a single photograph to help the beginning to moderate woodworker. These tips are too basic for the advanced woodworker, so I really don't see an audience for this book. It didn't help me at all. There's nothing wrong with the book -- if you want to read about other people's woodworking. However, to help you build your router skills there are wiser ways to spend your money. Several are sold right here on Amazon.
