Workpiece.Inspection
Some wood workpieces are not safe to cut or may require
modification before they are safe to cut.
Before.cutting,.get.in.the.habit.of.inspecting.all.
workpieces.for.the.following:
•.
Foreign.Objects.(see Figure.49):.Nails, staples, dirt,
rocks and other foreign objects are often embedded
in wood. While cutting, these objects can become
dislodged and hit the operator or break the blade,
which might then fly apart. Always visually inspect
your workpiece for these items. If they can't be
removed, do NOT cut the workpiece.
•.
Large/Loose Knots:.Loose knots can become
dislodged during the cutting operation. Large knots
can cause blade 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
blade and yields poor results.
•
Excessive Warping: Workpieces with excessive
cupping, bowing, or twisting are dangerous to
cut because they are unstable and can move
unpredictably when being cut. DO NOT cut
excessively warped wood.
•
Minor Warping: Workpieces with slight cupping can
be safely supported if the cupped side faces the
table or fence, as illustrated in Figure.50. On the
contrary, a workpiece supported on the bowed side
will rock during a cut, leading to loss of control.
