I have real easy teaching style and keep several of my goof-ups in the shop just to emphasize that messing up is part of the process.
I overlooked my best student when I said I had to finish most guys bows.
George wasn't an archer but he is an inquisitive guy, smart as they come. He called after making contact with another bow making friend who directed him my way. George had the fire, work ethic and interest. He had permission to cut osage on thousands of acres, went at it like a logging crew and soon had more wood than ten of us could use in a lifetime. He had so much good osage he discarded everything that needed a little heat correcting to the burn pile. I rescued truck loads of good osage from his reject pile.
Here is one of George's one day osage hauls. He split all this out in 100degree heat, took him a month. He wouldn't let me make the first splits with a chainsaw.
George is as tough as a hickory knot and was well over 60 when he did all the osage cutting.
He made bows and more bows but not being a serious traditional archer, the final tiller always remained a bit of mystery to him, his bows were incredibly well crafted, all works of art.
Then he moved on, as was his nature. Next was blade smithing, then bowl turning(osage makes spectacular bowls), then custom duck call making(osage barrels of course) and so forth.
The common denominator for all the good bow makers I know is they find almost anything crafty interesting. The guys who don't have it don't find anything one makes with their hands very interesting.
