If you canít stand the heat...
Using a bench grinder or belt sander is risky. You have about 1 second of contact before you create enough heat in the plane iron to adversely affect the tempering. Low speed wet grinders limit this if you have access to one. Using course grade sandpaper on a known flat surface with your sharpening jig, to rough-out the new shape, can help if your coursest stone is too slow. Even here be mindful of heat.
Better to invest the time to avoid risking the iron, than spend more time and $ trying to replace a ruined iron. Enjoy the new sharpening jig.
