This is the third Jim Richey "Methods of Work" book I have purchased. I have "Router Methods", "Table Saw Methods", and this one "Workshop Methods". I just wish I had known about them sooner. Each one is better than the next. I am not a professional, but I have always loved to do home improvement projects, repairs, etc. My father had a shop in the basement. once I retired and had more time I set up a small shop in my basement. These books are a gold mine. Jim Richey is an engineer, and his drawings are right on. I have made a number of the jigs and fixtures he shows and put them to good use solving problems on various projects. My favorite was out of Router Methods. A cool jig to cope molding rather than miter using a router. I built it, and used it to produce near perfect coped joints, and save time to boot. Great idea. There are many. I suggest before starting any project, look at the appropriate Jim Richey book. You may be surprised to find a little bit better way of tackling your project. These have become very useful tools. They are so good, I read them for fun and enjoyment, and enjoy building up an arsenal of tricks for future reference.
