SHARPENING LAWN MOWER BLADES (FIG. 10)
Lawn mower blades are usually sharpened on only one edge
and dressed up slightly on the other. Perform this sharpening
process on both cutting ends of the blade.
After sharpening, be sure to balance the blade by removing
additional material from the heavy end. Unbalanced blades can
cause serious crank shaft damage to your lawn mower. There
are a number of inexpensive cone balancers on the market for
this purpose. Alternatively, you can balance the blade using a
screwdriver that is secured onto a vise as shown.
NOTE: Always remove spark plug wires or battery from the
mower before servicing the blades to prevent accidental start-
ups.
SHARPENING CHISELS &
FLATHEAD SCREWDRIVERS (FIG. 11)
The end of a properly sharpened chisel or screwdriver will be
a perfectly flat rectangle, perpendicular to the center line of the
shank. The two sides and two faces will taper outward from
the end. Hold each face of the screwdriver against the wheel
to true it up, then ease the end straight into the stone to grind
it true.
SHARPENING DRILL BITS (FIG. 12)
Use the grooved work rest to provide angled support to drill
bits during grinding operation. The angled groove running
through the work rest allows for a cradle for drill bits during
sharpening operations.
For better sharpening results, you can use a sharpening jig
(available at most hardware stores). Begin on one side of the
point at the existing angle, then twist the bit while maintaining
contact with the grinding surface. Sharpen only the tip of the
drill bit.
SHARPENING KNIVES
Working from the heavy end of the blade towards the tip to
remove metal from both faces of the knife.
SHARPENING SCISSORS
If possible, take the scissors apart to make the sharpening op-
eration easier and safer. Remove material only from the out-
side surface and work from the heavy end of the blade toward
the tip.
