I made a post a few days ago about some hard maple that a buddy gave me that turned into firewood.
He also had a small amount of Hickory that in rough form looked fine, no holes, (usual end checks) etc.
Sending through jointer and some discoloration is starting to show through. Is this something to be concerned with i.e. diseased of some sort or just something a novice guy like me can live with. Hopefully the picture does it justice on what I am trying to convey
