I asked Paul a very similar question on his blog several months ago. He recommended Aldren Watson’s books. I now have two: Hand Tools, and Country Furniture. They are both terrific. The line drawings are 1000x better than photographs for visualizing what he’s talking about. I also highly recommend The Essential Woodworker, by Robert Wearing, reprinted by Lost Art Press. Also Illustrated Cabinetmaking, by Bill Hylton. And, of course, Paul’s book and DVD course: Working Wood 1/2.
I still think that Aldren’s book is the best book for me. I love to pick this book up over all others. It has such insights and the drawings encompass so many things you simply cannot get with photographs. He has given us a real legacy of knowledge and a respect for his father who taught him about woodworking.
I am working on new books as I type. Not sure which direction to go just yet. Looking for a good publisher right now and there are several options so I look forward to that in the near future.
