TYPES AND USES
Planes are smoothing tools used to true edges or sur-
faces of wood. Planes also are used where a finished
surface or close-fitting joints are required. Planes vary in
size and shape, but each is designed for a specific
purpose. The two types of planes most generally used
are the block plane and bench plane.
BLOCK PLANE
The block plane is the smallest type of plane. It is availa-
ble in a variety of patterns and is designed to cut end
grain with the cutting blade set between 12 degrees and
20 degrees. Although it can usually be used with one
hand, a toe knob is provided when additional pressure is
needed.
BENCH PLANE
One of the most common types of bench planes is the
jack plane. Like all bench planes, the jack plane is
designed for cutting with the grain of the wood. Its cut-
ting blade is set at approximately 45 degrees and is
used for all purpose planing or to cut lumber to specified
lengths.
