I highly recommend this book for any beginning woodworker who is thinking about buying, or has just bought, a router. I would also recommend it for those who want a different view on router tables and routers for those tables. I own Mr. Warner's three earlier router books, and his router CD. I find each to be useful in a different way. I'm glad I bought "The Router Book"; I've read it twice.
Some other commercially successful authors of woodworking books write about a wide variety of subjects with little, if any, insight. In contrast, Mr. Warner writes insightful books on a subject that he obviously knows well: routers. "The Router Book" gives a marvelous comparison between fixed base, plunge, and trim routers; why the differences are significant; and where and how to use each. I have two fixed base routers; I've used them a fair amount; and I'm comfortable with them. But this book gave me a good summary of routers and helped me identify the features that I want in a plunge router - it made me change the router that I plan to buy. The book also identified router bits and accessories that I found of interest. And his example of how to make a "comb" style template (such as you see on jigs for dovetails and box-joints) was worth the price of the book all by itself. I now find myself making templates for pieces I only need one of: I can work faster without concern about the costly stock, and the template controls the cut to give me better quality. Faster and better is hard to beat.
For those considering buying, building, or replacing a router table, Mr. Warner explains why he considers the usual solution of a plunge router on an insert plate an unacceptable compromise. His logic explains problems that I have had using router tables with inserts; and I could find no flaw in his explanations or suggestions. I've sold my fancy router table built on the "American Woodworking" design; I'm going to build a MARKEDLY simpler one based on his design - and I expect it to give more accurate results with fewer test cuts. (The book does not include a plan, but it shows and explains how it's built.)
I don't know any woodworker who wouldn't benefit from one of his books. After reading this overview guide, you should consider his two books on router jigs and joinery.
As much as I like this book, there are two things that I would change:
The title is somewhat misleading in that no one can reasonably expect a 179 page book to be "A Complete Guide" to anything. I'd delete "complete" and leave the title "The Router Book, A Guide to the Router and its Accessories."
The second change would be the publisher - which surprised me because this is a Taunton product and I am glad to own a number of their other books. Mr. Warner's earlier books used a large type face that gave attractive, easy to read pages. This book leaves ridiculously large margins and uses a much smaller type face. Taunton was also careless in that it printed some of the images reversed left-to-right so that you see a mirror image. Not the quality control that I expect from Taunton.
Neither flaw goes to the value of the book's contents: I STRONGLY recommend the book.
