SHARPENING
The leather stropping wheel on the sharpener
and the included abrasive stropping paste can be
used to obtain a razor sharp edge on many tools.
Before use, the stropping wheel must be properly
prepared. Figure 9.
To prepare the stropping wheel:
• DISCONNECT SHARPENER FROM POWER!
• Evenly apply a light machine oil to the leather
wheel. Use enough oil to provide a thorough
coating, but not so much as to saturate the leather
and result in dripping.
• Apply a thin coat of abrasive honing paste to
the leather wheel using a wooden spreader or
similar device. Distribute the paste evenly by
hand-turning the wheel while spreading.
• Connect the machine to power, then turn the
machine on and continue to distribute the paste,
still using the wooden spreader. Move the spread
-
er lightly in a circular motion across the wheel.
• Once the paste is evenly distributed, begin
sharpening.
FIG. 9
NOTE:
When grinding, metal objects become
heated quickly. It is important to keep moving the
object back and forth across the face of the grind
-
ing wheel and to cool the object frequently using
the coolant tray.
• These preparations will be sufficient for
sharpen
ing five to ten tools. If you notice a drop in
sharpening performance or have sharpened more
than ten tools, repeat the above steps.
NOTE:
A slight wobble of the stropping wheel
when it is rotating is normal and does not affect the
performance.
WHEEL DRESSING
Depending on the type of grinding you do, the
grinding wet wheel may require periodic dressing.
A variety of dressing tools are available separately
(abrasive stones, diamond tipped dressers, etc.)
and can be used to restore the abrasive quality of
the wheel.
Dressing will remove buildup up of material on the
grinding wheel, remove imperfections and make
the corners of the grinding wheel square. Refer
to the instructions that accompany your dressing
accessory for complete details on how to properly
dress a wheel.
Typical wheel dressing steps:
1. Adjust tool rest until it is in the flat, horizontal
position and about 1/16” away from the grinding
wheel.
2. Turn “ON” the machine and after the wheel
has
gotten to a steady speed, place the wheel
dresser head flat on the tool rest.
3. Firmly hold onto the dresser so that it will not
slip at any time during the dressing process.
4. Move the wheel dresser forward until it makes
light contact with the wet wheel. After contact has
been made, slide the wheel dresser side to side
across the tool rest to dress the grinding wheel
until the edges of the grinding wheel are square
and the surface is clean.
5. After the dressing the grinding wheel, turn
“OFF” the machine and let the grinding wheel
come to a complete stop. Inspect the grinding
wheel for any irregularities that still need to be
dressed, or for any damage. If there is damage to
the wheel (cracks, major chips missing), replace
the wheel immediately.
6. The grinding wheel may now be slightly
smaller in diameter after dressing. Re-adjust the
tool rest to maintain a 1/16” clearance to the grind
-
ing wheel, and re-dress the stone if necessary.
