I measured my spine to head and came up w/about 36". I like the idea of a 1 pc 40" bow quick and easy to string. No takedown to put together. Drawing about 20-22 inches, 40-45#, Osage D bow, sinew backed w/ skins to waterproof. Possibly Black Locust in the same dimensions (Just happen to have a good dry piece). Do you think this is possible?
