Using Featherboards Workpiece Inspection
Some workpieces are not safe to cut or may
require modification before they are safe to cut.
Before cutting, inspect all workpieces for the
following:
• Material Type: This machine is intended
for cutting natural and man-made wood
products, laminate covered wood products,
and some plastics. Cutting drywall or
cementitious backer board creates extremely
fine dust and may reduce the life of the
bearings. This machine is NOT designed
to cut metal, glass, stone, tile, etc.; cutting
these materials may lead to injury.
• Foreign Objects: Nails, staples, dirt, rocks
and other foreign objects are often embedded
in wood. While cutting, these objects can
become dislodged and hit the operator, cause
kickback, or break the blade, which might
then fly apart. Always visually inspect your
workpiece for these items. If they cannot be
removed, DO NOT cut the workpiece.
•
Large/Loose Knots:
Loose knots can become
dislodged during the cutting operation.
Large knots can cause kickback and machine
damage. Choose workpieces that do not have
large/loose knots or plan ahead to avoid
cutting through them.
• Wet or "Green" Stock: Cutting wood
with a moisture content over 20% causes
unnecessary wear on the blades, increases
the risk of kickback, and yields poor results.
•
Excessive Warping:
Workpieces with
excessive cupping, bowing, or twisting are
dangerous to cut because they are unstable
and often unpredictable when being
cut. DO NOT use workpieces with these
characteristics!
• Minor Warping: Workpieces with slight
cupping can be safely supported if the
cupped side is facing the table or the fence.
On the contrary, a workpiece supported on
the bowed side will rock during a cut and
could cause kickback or severe injury.
Featherboards are used to hold the workpiece
flat on the table and snug against the fence.
The Model SB1119/SB1120 includes two fence
featherboards: one for infeed and one for outfeed.
An arrow on each featherboard indicates the
direction of workpiece travel.
