The surface of a board having a grain that runs both ways is very hard to smooth with a plane. By sharpening the plane iron to a keen edge, then placing it in the plane with the cap reversed and set about 1/32 in. from the cutting edge, I find that with a light cut the plane will smooth regardless of the direction of the grain. - Contributed by William Rollins, Wichita, Kansas.
