For me, I had hands on help from an experienced bow maker on my first. I did the work, but under the watchful eye of someone who knew through making them, what to do and not to do. Like you, I had read everything available to me up to that point. With all that book knowledge, I really didn't know sic' em from come 'ere. First one turned out great. Still shooting it nearly 20 years later. The next several were more of a challenge as I was on my own. Some worked, some didn't. Every stave is different, requiring a different approach to certain things. Still, the instructions I got on the first one, translated into hands-on knowledge and experience. Straight up the learning curve early on, and more of an ability to parlay that experience on the next one. This may not be of much help to you if you have no access to an accomplished bow maker. If you do, bribe, or beg, them for help. Usually, just asking is all it takes for most I've known. If you don't know any, and you will go it alone, realize that your learning what not to do by doing it, as opposed to someone saying "don't do that" and saving you the time. A much tougher slog, but with persistence and bulldog determination, you'll get there.
Edit; Above I said "the next several were more of a challenge". Upon reading that, I submit this change. "All my subsequent bows were more of a challenge." Every stave I've worked has presented a new set of challenges, requiring a different approach than the last. And to this day, some work, some don't. My success rate is simply higher now.
