Nov 20, 2010· While I don't endorse the idea, it does work, but not well. I have used the process for sharpening planer blades for a neighbor, but would have chosen to use my surface grinder had it been operational. One problem you face when grinding with a mill is the inability to move the wheel fast enough to prevent burning of the part.
