Sharpening Narrow
tools
the stationary clamps mounted on the pivot sup-
port hold tools with narrow cutting widths, such
as chisels, that have a beveled edge which can
be squarely aligned with the flat of the wheel, as
shown in Figure 12.

2.
install the pivot support onto the grinder table
with the two stationary clamps attached.
3. Center the tool on the pivot support between
the clamps, slide them together to firmly hold
the tool, then tighten their knobs to secure
them in place, as shown in Figure 12.
4. loosen the table lock, then use the table
handwheel to lower the grinder table until
the top surface of the wheel is even with the
table.
5. adjust the angle of the pivot support and its
position on the table and in the clamps so
that the tool bevel just makes contact with
the wheel, as shown in Figure 12, then make
sure the stationary clamps and four pivot sup-
port lock knobs are tight.

once you are satisfied with the position of the
tool relative to the wheel, raise the grinder
table slightly above the wheel, then turn the
grinder ON.

While firmly holding the tool on the pivot sup-
port, slowly and carefully lower the grinder
table until the tool contacts the wheel to begin
sharpening the tool.
Note: Keep in mind that with a dry grinding
operation, tools can heat up quickly and lose
their temper. Sharpening should be done in
light passes and for short durations to avoid
damaging the tool or wheel.
tip: Apply marker ink to the full beveled sur-
face of the tool to help verify when the tool
is properly ground. Also, a fine straightedge
held to the bevel will show any variations.
cutting tools are dangerously sharp, espe-
cially after sharpening. Use extreme caution
when handling these tools to reduce the risk
of personal injury.
Sharpening Wide
Knives
Wide knives, such as jointer and planer blades,
are firmly held in the slide bar assembly that
is then mounted on the slide table above the
wheel.
