I have a couple of staves of black locust I split from a 8" diameter tree felled at a powerline cut.  I peeled the bark then painted ends and back, waited a while, began getting rid of sapwood.  Meanwhile the belly of the better stave checked a little in the handle area and into the fades.  The stave still is too thick but I think this check will remain.  It does not go to the back, yet, and the back is fine.  Should I turn it into firewood or continue to work on it?
It has knots and some borer damage in the handle area.  Character bow if I save it.
