I have a crazy idea: I have my surface grinder running no and have a stack of dull drill bits (1/8"-1") to sharpen. I lack the skill (and the willingness) to sharpen them by hand on the bench grinder, so I want to sharpen drill bits using the surface grinder. Has anyone done this? I am thinking of a simple jig to hold the bits at the right angles, anyplace I can go for more info?
