Mk.II Power Sharpening System
Buffing/ Honing
Although the edge produced by the 9µ abrasive is
extremely sharp and should meet the needs of all
woodworking tasks, it is possible to take the sharpening
process a bit further. To make a honing disc for use on
the system, extra platters are available. (See
Appendix
B: Optional & Accessory Parts
.) Simply use spray
adhesive to adhere some thin, tightly woven cotton fabric
to a
3mm
platter. (The material from a old dress shirt
is ideal for this.) With the power on, charge the honing
disc with green (chromium oxide) honing compound.
Note:
The platter retention thumbscrew is not self-
tightening and may unthread itself under load. This is
a safety feature that helps to prevent injury or damage
to the sharpening system if for any reason a blade digs
into a platter while sharpening. To prevent the honing
platter (or any platter that has no abrasive on the
underside) from coming loose under a normal working
load, apply a thin coat of rubber-based spray adhesive
to the underside of the platter. Let it dry for a few
minutes before use.
To Use:
•
Keep the tool clamped in place in the holder when
finished with the 9µ abrasive.
• Secure the platter with the honing disc (fabric
side up) to the turntable in place of the other 3mm
platter (with the 40µ and 9µ abrasives).
•
With the power on, apply the blade to the rotating
honing disc in the same manner as for regular
abrasives,
but on the left side of the turntable to
make a trailing cut (Figure 21)
.
Note:
Honing must be done on the left side of the
turntable so that it creates a trailing cut – i.e., it must be
a stropping action where the honing medium is moving
away from the edge. If a leading cut is attempted, the
edge of the blade can catch in the honing disc and
force the tool backwards, possibly causing injury to the
user. Again with a trailing cut, remove the wire edge by
applying the face of the blade fl at against the rotating
honing disc.
Note:
Make sure the blade does not contact
the platter retention thumbscrew while the
sharpening system is turned on.
Convex Cutting Edge
Used properly, the system will create a straight cutting
edge square to the side of the blade. This is the most
desirable result for chisels and most planing situations.
However, depending on user preference and the task at
hand, sometimes a very slightly convex edge is ideal
(e.g., to avoid corner digs when smooth planing). This
can be easily achieved when honing with 9µ abrasive.
Instead of applying pressure straight down in the middle
of the blade, press alternately on the two front corners.
