When I made my first Osagebow, about12 or 13 years ago I was very careful working with this wood. I was astonished how much more power and strength this wood covered. My bow was shorter than my others, the limbs weren`t as wide and there was so much strength. I don`t know if there exist a pic somewhere, but she looked and she shot got (still she does, although I shortened and retillered the bow).
Later somebody told me that Osage will still give a good bow, even if Newbies do it (I think the Newbie must already have good tillering experiences, because the wood is to expensive (in Germany/ Europe)).
