    Is the Aluminum Oxide just in the finish or also in the wood itself? I have a 4-1/2″ angle grinder with a 40 Grit Zirconia Alumina flap disc and it removed the coating in this small section in no time. (My thought/question is, if the aluminum Oxide is only in the finish shown removed in this picture, I can use the angle grinder to aggressively remove just the coating on everything then on the real high spots of which there are a lot, I could use the drum sander (or edge sander?) on the wood after the coating was removed and hope it would work much faster. My fear is that even if I purchase a 7 or 9″ angle grinder it will take a long time removing the high spots and more difficult to get clean and even.) Cutting the floor out the floor in the high spots is out because there are a lot of them and the floor is glued and probably nailed too.
