Good Goobity! That is ridiculous! Love the thinness of your limb tips! I have wanted to take the thinness down to that level on the three osage recurves I've built, but they have been so crooked/twisted etc that it took a serious amount of heat correction to get the string tracking center belly...and despite getting them to track center-belly or damn near it, I was still scared to lose the "protection" of the width. I think that is probably not a problem (string jumping off the side and unstringing at shot) that I should even be worried about, as they have all shot fine, but it has bothered me to the point of not getting my tips that skinny...yours are beautiful and undoubtably factor into your ability to get that kind of speed.
Your string grooves/nocks are magnificent! I would appreciate GREATLY if you would film yourself working those into shape and post it on youtube or take stills and post them here. Are you doing that with a chainsaw file? It seems like you have to have a "secret weapon" for that...its amazing. Great job on that build. That is something to shoot for fo sho!
