I have read a couple of books on bowmaking and traditional archery in general. For instance, I hugely enjoyed, and profited from, Comstock's Bent Stick and various German books on the subject. Yet, being a physicist, I liked this one best.
Approaching the subject in a thorough, almost scientific manner sure did appeal to me, but I am convinced the book still succeeds in making its invaluable guidance palatable and digestible even to the layman who wants to nothing but build and shoot traditional bows.
1) I have not found a better description of bow physics anywhere else,
2) the chapters on yew and osage orange, while being dedicated to these specific woods, are still sufficiently general for any bowyer to profit from the, and they are complemented by a chapter on "other woods",
3) the description of the tillering process is the best and most encouraging I have ever read (and, trust me, I have read quite a few),
4) the chapter on self arrows is so full of information that I fail to identify a particular issue addressed.
All in all, when reading the book and highlighting the eye-opening passages, I was glad I did this during a vacation and had a lot of time, because there is just so much stuff that I either failed to read anywhere else or never found so well put before.
To me, it sure is the most comprehensive, instructive and valuable book on bowmaking currently available.
