SHARPENING BLADES
Refer to Figure 21.
The blades can be honed individually by whetting them
with a fine sharpening stone. Make sure oilstone is flat
and is not worn. To sharpen blades:
• Partially cover the stone with paper to protect the
table top.
• Position infeed table so stone will contact blade
along its beveled surface.
• Stroke the stone across blade from one side to other
while stone is also moved slightly in the direction of
feed.
• Make sure to do the same number of strokes on
each place.
If the blades are nicked they must be replaced or
reground. They can be reground several times until they
become 13/161' wide.
NOTE: Many shops do not have capabilities to resur-
face blades. Yellow pages should list "Sharpening
Services" or "Tool Grinding."
