I know in general- osage Orange is as dense as Ebony -it will not float it is that dense . It also turns a funny brown after several years
-not sure if a finish would stop that -youd need to talk to your luthier . i have two fingerboards of Osage orange and a set of 2 bookmatched sides for a Mandolin
( the fingerboards were intended to be mandolin sides ) thou they have browned their beautiful pieces of wood .
(As ive been told ) Osage orange was used as fence enclosure material before Barbed wire - more of a primative tactic ( very slow growing wood )
-it is very hard to find in wide enough pieces to be usable for guitar wood .
