Well, since you're asking for opinions, it sucks. There are far better books out there.
Which ones? What books on building do you recommend?
Recreating the American Longrifle
Art of Building the Pennsylvania Longrifle
I have those books. At least I had those books. I gave away the Art of Building the Pennsylvania Longrifle to a starting builder who had no other resources.
I started building with Recreating the American Longrifle. It was all there was at the time. Peter Alexander was the last editor of Recreating the American Longrifle and included the same content in his book.
One thing I think Peter did to improve on Recreating the American longrifle was illustrations showing how to shape the various sections of a stock. That is a really hard thing to try and explain. You might not do it the same, but I believe those illustrations are very helpful to beginners.
I look at the Gunsmith of Grenville County as an encyclopedia. It is a broad introduction to the subject and a good jumping off place for further research. I have never seen another book that does that. The only way I could think to improve on Peter's work is to add video, which he is doing.
Instead of just saying that you don't like something or something sucks, why not explain why you don't like it and give some examples of what you do like.
