LAWN MOWER BLADES
1. Ensure there is adequate working space to maneuver
the blade.
2. Sharpen the blade’s beveled side first, then dress the other
side with the grinder or a file.
2.1 Remove any nicks present on the cutting edge. Rest
the blade flat on the tool rest and move the blade side
to side until the edge is nick free.
2.2 Sharpen the bevel. Either adjust the tool rest angle to
match the blade’s bevel angle or hold the blade at the
bevel angle while resting a portion of the blade on the
tool rest for added stability. Remove as little metal as
possible to attain the desired edge. Lightly dress-up
the flat backside of the blade.
2.3 Do not hone the lawn mower blade to a razor-like
sharpness. This increases the likelihood of nicking the
blade and promotes rapid dulling. Use a file or the
bench grinder to slightly dull the cutting edge.
3. After the blade is sharp, check the blade’s balance with an
appropriate shop made jig or commercially available unit.
Balance the blade by progressively removing metal until
balance is attained.
CAUTION!
An unbalanced lawn mower blade may cause
excessive vibration, damaging the mower and engine shaft.
SHARPENING SCISSORS
Take the scissors apart, if possible, to make the sharpening
operation easier and safer. Remove material only from the
outside surface and work from the heavy end of the blade
towards the tip. Finish the edge with a whet stone.
SHARPENING TWIST DRILL BITS
Sharpening twist drills can be a tricky operation that even
some experienced mechanics never master.
