Michael ,I'd reduce the width of that stave to remove the damage.Plus,you don't mention the lenght,but it looks pretty long in the picture.Osage is great narrow,in fact,IMO,it's better narrow.Those cracks do happen,but, make sure you have your wood plenty hot,(without scorching),and go easy on it.After you've done a few,you'll get a feel as to how much a stave will take.God Bless
