I'll second the Clay Hayes videos. I subscribe to his patreon page, but that is not necessary to access a ton of his videos showing bow building from start to finish. Clay primarily works Osage, which I honestly think is the place to start with primitive bow building; it is plentiful if you are willing to drive and work to get it down, split, and sealed, and it is a very satisfying wood to work into a bow...and as far as bow wood goes, it is the tits. Start with BB vol 1, and just take the time to read it from start to finish. It can be used as a reference guide, and I use it as a reference guide all the time, but starting off by reading it from start to finish is worth the time it takes...have a highlighter handy and maybe a journal to jot down some "ah-ha" revelations. Ten years from now, you will still be bending those pages and having "ah-ha" moments. The other volumes are fantastic too, and they just build on and give more depth of understanding to what is in each of the other volumes.
That said, Weylin's vids are great, and he is a freaking master. Clay's vids are different, and I think that they move along more quickly for the ADD crowd. There is no doubt that any Jo-shmo off the street that wants to build a primitive bow could click on Clay's videos and having absolutely no clue about anything archery related, build a pretty damn good bow by simply following his instruction.
My advice is to watch Weylin's vids, watch CLay's vids, read BB vol 1, and start making shavings pronto...dive the heck in head first. You said it, and it is true...there is no better teacher than experience, and there is no better way to learn than by trying and failing...and no matter what happens, you will fail in some aspect of the build. One day, my truest hope in this endeavor, is to build a bow that I can not in any way ID some aspect of a failure; it likely will never happen, but that's my goal. In the mean time, there is tremendous beauty and joy in every bow's flaws...it makes them so freaking personal and relatable, while propelling us to make a better one next time.
Cheers, and welcome to the addiciton!
