I sharpen all of my bench planes with some degree of camber, or curve, to the cutting edge. Doing so eliminates plane tracks when the planes are used to dress the wide faces of a board, and makes squaring an edge easier than it is with a straight iron. There are multiple ways to achieve putting a camber on the edge of a plane iron.
About a year and a half ago, I made a video demonstrating the method I use to add camber to a plane iron using a high speed grinder. You can find that video here.
However, if you don’t have a grinder, that doesn’t mean that you can’t camber your plane blades. You can get the same amount of camber using only a honing guide and a coarse stone. So in today’s video I’ll show you how to camber a plane iron without a grinder.
