2-4. Smooth Facing Tools.
a. Types. Smooth facing tools called planes, are sharpedged
cutting tools in which the cutting edge is guided by the body of the
tool instead of by the hands. The place bit, for example, is
positively guided by contact of the body of the tool with the work,
giving a smooth cut in contrast to the rough cut made by handguided
chisels.
(1) Hand Plane. A plane is a finishing tool used for smooth
surfaces (Figure 225). It consists of a wood or iron stock or a
combination of the two, with the cutting edge projecting from a slot
on the underside. The cutter inclines backward and has a chip
breaker in front to dispense the shavings. The plane is light and
easy to use in finishing and bringing wood down to the desired
thickness. Hold the plane with both hands and, with long strokes
push it away from you.
