I had an osage bow that I hunted with for several years, the grip fit my hand better than an bow I have ever made. It was a good but not great shooter. It started developing mysterious cracks on the back .
I would sinew wrap a cracked section, shoot the bow a few months and another place would crack, more wrapping.
When it cracked for the third time I said "to heck with it" and put the bow up.
One day I was thinking about that great handle, how it fit my hand so well and decided to try to save the bow.
I removed the sinew wraps, put the bows back on my belt sander and went to work. When I had the bows back flat, I carefully cut a piece of bamboo to fit it. I glued the bamboo on the bow adding 3" of reflex. After re-tillering I couldn't believe what a great shooter my ailing bow had become.
This BBO has been my favorite bow for the last 3 years.
