I went backwards. My first try at a hickory board bow turned out very good. Still have it downstairs and bring it out to shoot now and then. But after that, I'll bet I busted over 20 diff. bows. I busted hickory, oak, elm, black locust, black walnut, you name it, I broke it. Maple, I broke more maple bows.
This was back in the mid 90's and all I had to go from it Laubin's Indian Archery book. Then I found the bibles, also Murray Gaskins had a site with directions, oh, and Prim. Archer mag. had the bow building issues. I got all of them, cut out the bow building part and made my own book.
Still have the cut outs and ref. them along with the bibles and yes, I still ref. Laubin. Lately though I've just clicked over to Jawge's site. Been building bows since 95 and sometimes still feel like a greenhorn.
You'll get it and then you will make a good run on bows. Then you'll break a few then you will get back on board. LOL. Or stave.
