TYPES AND USES
Planes are smoothing tools used to true edges or
surfaces 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
available 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
cutting blade is set at approximately 45 degrees and is
used for all purpose planing or to cut lumber to specified
lengths.
SAFETY
1.
Be careful to plane work smoothly to avoid
splinters that may be left to cause injury.
2.
Use each plane only for the job it is intended.
3.
Keep all cutting tools in good condition.
4.
Do not allow tools to lie around work areas in
such a position that they may cause injury to
others.
5.
Before using, inspect the tool for damage or
other defects. Repair or replace immediately if
required.
