Work Sharp Sharpening System - Manual (Page 28)

This photo shows the slotted plate and
slotted abrasive. They are the same
150mm in diameter as the glass plates
and mount the same way. The difference
is these are one-sided with the abrasive
always down.
I like to use two of these slotted plates,
one with P400 grit mounted and the other
with P1200 grit mounted. Lathe and
carving tools generally come new with the
bevel edge well formed, just not very
sharp. Also, they seldom suffer the
abuse that chisels and plane blades
experience so seldom need coarse
grits to take out chips or bad nicks.
I find the P400 does a good job of tak-
ing out the bad grinding marks left if the
tool had previously been “sharpened”
(more like butchered really) using a
typical vertical stone on a bench
grinder. It is plenty coarse enough to
correct most edge flaws you will en-
counter.
The P1200 does a great job of detailing
a really fine edge, and there is not
normally much need to go finer than
that, given the way lathe tools
cut. Hence, two of these slotted
wheels will do well for most appli-
cations. You can always just use
the one that comes with the Work
Sharp and change the slotted
abrasives as you work, but the
cost for the second slotted wheel
is modest compared to the time
you will save.
These abrasives have a sticky back just
like the solid abrasives used on the glass
plates. They install the same way as
well. Just peel and stick.
