We are thinking exactly the same way! With the bench top that is stuck to the slab I think ill start with a old chisel and hammer, then on to the belt sander. Plan is to get the bottom cleared off then switch to the router leveling jig for the top to skim it off. I will also be taking it to be run through a widebelt sander. All the more reason for me to continue shopping for the 37" drum sander ?
I think for the top coat on this that I might get a top coat epoxy, with as much epoxy that ran off the edge it might blend in better. Will find out more tomorrow night when I tear back into it.
