nice to see a young guy wanting to work. listen man, i think you have a pretty good understanding of what your doing, but there is a lack of patience getting in your way. im guilty of it too, i get in a rush for no reason and i end up having something in every bow that bothers me. i know you're young, and i try to remember being your age (and believe me, you are being way way more constructive at your age than i was), but dude i would really love to see you take a piece of GOOD wood, not a board, or an iffy tree branch you found, but a nice stave (save your lunch money or something) and TAKE YOUR TIME on it... not an hour, not a day.... a MONTH! and get some sandpaper or a cabinet scraper. I challenge you to make a finished bow. one that someone can hold up in the sunlight and turn it over and over and say "wow! You made that?!" . i haven't seen all your bows, or all your threads, but ive seen many, and i think maybe it wouldn't kill you to ask advice or opinions at different stages of a build, and take the advice. hope you accept my challenge, and good luck to ya.
