OK, I have seen most of them and I will say there is not or has there ever been a video out there that you can watch and learn step by step how to make a bow. You will pick up some good pointers on all of them but will not learn how to make a completely finish a bow, they all leave something out. They have to cut corners or the video would be at least 5 hours long.
They do pretty good on stave selection, layout and floor tillering could be better, tillering; an all day process for me is condensed into just a few minutes on the videos and is a bit vague.
Here is the biggie that is always omitted; problem solving, what do you do if something doesn't go as planed, heat corrections, limbs out of time, string not centered on the handle, hinges and a host of other things I run into every time I make a bow.
As for the Bowyers Bibles; volume one is the one you want first, more bow making info then 2 or 3. I had two and three as well, I have never seen #4.
