Adjusting And Replacing Scoring Blade - Grizzly G0493 Owner's Manual

adjusting and
replacing scoring
blade
the scoring blade included with the sliding table
saw has wedge shaped teeth. the kerf thickness
of this style of scoring blade is adjusted by chang-
ing the height of the scoring blade.
Most replacement scoring blade sets consist of
an inner and outer blade with internal shims.
the shims are provided so the scoring blade set
can match the kerf thickness of the main blade.
figure 68 shows a replacement scoring blade
set laid out for identification. For optimum per-
formance, replace the scoring blades when they
start to get dull.

6. adjust the width of the scoring blade to equal
the kerf thickness of the main blade.
the scoring blade included with the sliding
table saw has wedge shaped teeth. the kerf
thickness is adjusted by changing the height
of the scoring blade until enough of the tooth
is exposed to equal the main blade kerf. if
you are re-installing this style of blade, adjust
the kerf after step 7 with the scoring blade
vertical adjustment controls.
7. install the new scoring blade, re-install the
arbor flange and the arbor nut, and tighten
them against the blade set.
8.
Move the orange blade guard back into its
original position, next to the blades, and cen-
ter the sliding table.
9. Move the rip fence against the main blade (or
scoring blade).
10. adjust the scoring blade, using the horizontal
adjustment controls, until the rip fence can
touch both blades.
11. perform a test cut and check for chip out on
the underside of the test piece. if there is
chip out, make the adjustments necessary to
match the kerfs.
