41 forum posts 1 photos	I am looking for a plan to construct a radius jig for the Harold Hall grinding table. I would like to grind radiuses on HSS tool shafts and I would like to sharpen ball shaped milling cutters. I am thinking in the line of adding the Harold Hall end mill attachment on top of the radius jig or the other tool holeder to clamp HSS rods or shafts. A picture / photograph from where I can get an idea will also be appreciated.
