My neighbor gave me this 2" oak slab. Its dang nice but the edge has a lot of wet rot. I am comfortable stabilizing the crack with bowties and the knot with epoxy before finishing, but any advice as what to do with this rot at the edge?

Was thinking about taking a flap wheel sander to it. The higher mag pic is after I dug at the edge with a screwdriver.

Ultimate goal is either a coffee table (maybe not this one) or may cut it half and make an interesting shelf.
