Query: should have gotten a different book

The problem is that the book is ALMOST helpful. It seems to be giving simple instructions. But when I try to learn anything (and I am a mechanically-inclined non-dummy) I find there is just not quite enough to get from one step to the next. I frequently found myself spending an entire hour poring over 2 pages, trying to visualize what it is saying, and failing. It would have been so easy to add an additional step, or make clear whether the right side or the wrong side is showing in the drawing, or a simple photograph of a finished product, and it just doesn't.The best I can say for it is that it gave me enough information on any particular topic to look it up on the internet and get useful help.
