John, dummy me! My mind was in the wrong track. Of course, "disk grinder" among knife makers is a "disk grinder"... Works great for flattening surfaces from small imperfections. Got one myself that uses 8-1/2" X 11" sandpaper glued on, then cut in a circle.
I've wondered about your question also - I've got an 8" aluminum disk I've planned to rig up on the mill and see how that works. I suspect it will work better than the grinder disc I'm currently using on the mill. That grinder disc has a good bit of run-out on it. The disk from the vertical disk grinder would be MUCH less. I think it would be better..... I think.
