In this video, I demonstrate using a high speed grinder to camber the cutting edge of a jack plane blade (I'll discuss another method in a separate video). I also discuss how much camber I use on this blade, and how I go about marking the camber on the blade before grinding. The method I use for marking the amount of camber works for any iron width or bed angle, even if you don't know what the bed angle is (like for an old wooden plane), because there's no math involved.
