Topside Sharpening
STEP 1 • Mount Top Tool Rest
Mount the Top Tool Rest as shown on pages 7–8.
STEP 2 • Select Top Tool Rest height to
determine angle
The height of the Tool Rest above the wheel and the tool projection off
the Tool Rest determine the bevel angle sharpened. Lay the tool to be
sharpened across the Tool Rest and onto the Abrasive Wheel surface.
Be sure that the bevel is laying flat on the Abrasive Wheel surface.
Raise or lower the Top Tool Rest to find the proper bevel angle desired.
See fig. 7-1. Check the
Tool Rest for level by using
a common level. Once you
have located the desired
height and level of the tool,
tighten the 2 thumbscrews
to secure the Tool Rest. Do
not over-tighten.
STEP 3 • Sharpening
Once proper Tool Rest height and tool projection are determined, sim-
ply lay the tool on the right side of the Tool Rest and contact the Wheel
surface while the unit is turned on. Similar to the bevel grinding in-
structions for the Sharpening Port, start with a coarse grit Abrasive
Wheel for damaged tools or tools that need to be ground to new angles.
For tools that need to be sharpened, start with a finer grit Abrasive.
Please refer to "Selecting the Right Abrasive for the Job" (p. 10) for
more information concerning grit selection. Working on the right side
of the Tool Rest allows you to sharpen with the Wheel turning away
from you. This is the best position on the Tool Rest for optimum control
during sharpening. Sharpening in this manner also draws a burr wire
onto the edge of the tool, so you may need to touch the back of the tool
being sharpened onto the Abrasive Wheel surface to remove the burr
wire.

Master Tip
Be careful not to grind too aggressively as it will generate heat
in the tool being sharpened. If the tool being sharpened is get-
ting warm to the touch, simply stop sharpening for a moment
until the tool cools down. This will help ensure against damag-
ing the tool steel.

Edge-Vision™ Slotted Wheel
The following instructions explain how to use the Edge-Vision™ Slot-
ted Wheel to sharpen carving and lathe tools.
STEP 1 • Select the proper Abrasive
For carving tools
These tools should be sharpened using the provided Edge-Vision™
Slotted Wheel and abrasives, then final honed using the provided Mi-
cro-Mesh™ Hone Wheel. Caution: using too coarse of an Abrasive on
smaller tools may cause the tool to overheat. If a carving tool has dam-
age on the cutting edge or needs to be shaped to meet your needs, start
with a coarser abrasive wheel and sharpen until damage is removed or
desired geometry is achieved. Then proceed to a finer grit slotted media
to refine the cutting edge and surface finish. Use the Micro-Mesh™
hone to polish tool until desired finish is achieved.
For lathe tools
Lathe tools are more tolerant to coarse grinding and do not need to be
honed to a mirror finish. For these types of tools you can achieve work-
able sharp results using the coarser slotted Abrasives.
STEP 2
Edge-Vision™ Slotted Wheel
If you have not already applied the Slotted Abrasive to the Edge-Vi-
sion™ Slotted Wheel, refer to the instructions on page 8. Standard 6"
abrasives can be used on the Edge-Vision™ Slotted Wheel. Trimming
will be required.

STEP 3
Slotted Wheel
The Edge-Vision™ Slotted Wheel mounts to the unit the same as the
tempered Glass Wheels. Always mount the PSA Abrasive face down.
With the slotted wheel safely mounted and the unit turned on, you
should be able to see through the slotted wheel clearly for sharpen-
ing carving and lathe tools underneath the wheel. A standard shop light
or spot light can also be used to shine on top of the slotted wheel during
use to aid in the visibility of the cutting edge.
STEP 4
tools with the Edge-Vision™ Slotted Wheel
With the Edge-Vision™ Slotted Wheel properly mounted, you can begin
sharpening your radius carving and lathe tools. Orient the machine so
that the back of the machine is facing you and turn the WORK SHARP
unit power switch to the on position. Slowly and carefully approach
the WORK SHARP
the tool. Looking down through the Edge-Vision™ Slotted Wheel, you
should be able to see the tool to be sharpened. See fig. 8-1. Slowly
approach the wheel with the tool to be sharpened and place the heel of
the tool onto the abrasive surface. You should be able to see the exact
point of contact between the wheel and tool being sharpened as you
look down through the Edge-Vision™ Slotted Wheel. Slowly and
carefully move the tool being sharpened on the abrasive so the entire
bevel heel is sharpened. Now carefully roll the surface being sharpened
up to the cutting edge.
Continue until the entire
cutting edge is sharp.
See fig. 8-2. Once the
tool has an edge you
are satisfied with, you
can stop sharpening.
You can also mount the
Micro-Mesh™ wheel to
hone a mirror polish on
your tools if you desire.
