Google "Bowyers Diary", the search facility on the blog works quite well and there is plenty of stuff on there and you can follow many bows from stave through to finished (or exploded!) bow.
Here is a link to one of the posts:-
Bowyer's Diary: Roughing Out Figures and Technique
I've also done a complete youtube build along for a Yew English
Longbow, there 10 parts, here:-

It covers absolutely everything from a quarter log to a finished bow including detail of horn nocks arrow plate inlay etc.
My blog started as an aide memoir but became a useful resource for one and all.
BTW, you can't make a bow from a stave "by numbers", so beware of any chart that implies you can. It's a different matter with nice even slats of machined timber for a laminate bow, you can get much closer to finished dimensions much quicker.
The biggest thing to learn is to go slow, spend at least as much time thinking and looking as you do removing wood. And keep away from power tools once the stave is flexing at all!

PS, Just remembered, in January I made a Yew
longbow 50# at 30", you can follow the whole build starting from here:-
