This method of holding non-magnetic plates on a surface grinder is a precise way of grinding when the workpiece is too large or cumbersome to be held in a vise or cradled w/ steel plates. I used molten sulphur & mixed it w/ lard oil. The mastic was then applied in a bead all around the bottom of the workpiece & allowed to harden. Light cuts were then taken on the work surface with a 36-F or G silicon carbide wheel. It will produce a nice finish & also grind the work flat. Of course melt the sulphur outside unless you have a strong exhaust system. When finished grinding, use a sharp flat chisel to break up the bead & clean up your mag chuck.
