Set both dials at 0° to the register marks.
Then, slide the xture onto the base post
and hold it out in front of you. Position the
xture so that it is square to your body
and the tool being sharpened is pointing
“straight” away from you (FIG. A). It should
look like an inverted “L” or “˥”. As you
change this angle, the position of the xture
will rotate down (FIG. B).
The TOOL DIAL, can turn left or right 360° plus, but always use
one of the 0° as a reference point. After grinding the face angle,
turn the tool over (180°) by rotating from reference point 0° to new
reference point 0°. Now you can set the angles desired, left and
right, from the new 0° reference point.
GETTING THE GRAVER READY TO SHARPEN
Most tools need some type of preparation before sharpening.
Shank modication to t a hand handle or power handpiece, or
just shortened to t your personal
needs. GRS Tools does offer
gravers that are already modied
and ready to be sharpened.
Removal of excess metal from the
top/front tool tip makes it quicker
and easier to be re-sharpened, plus allows a better view of the
tip when in use. For this you will need to use a bench grinder or
a Power Hone with a 260 grit wheel will work. Rough grind with a
bench grinder rst, then true the surface with the Power Hone if
you desire. When using a bench grinder, eye protection MUST BE
WORN and a face mask to prevent breathing wheel dust.
Tools can easily be damaged while grinding. Do not let the tool
tip get hot and burn. Burning means the tool metal will turn blue,
which takes the temper or hardness out of the tool and it will not
hold a cutting edge. To avoid burning the tool take your time and
do not press too hard against the wheel. Have a container of
water by your grinder and frequently dip the tool BEFORE it gets
warm in your hand. Some suggestions on how to pre-shape the
graver.
MOUNTING A TOOL IN THE TOOL DIAL
Open and close the jaws by turning the Jaw Thumb Screw.
The illustration below shows the correct placement for holding
square and traditional
gravers. Properly position
the graver squarely in the
jaws and tighten snugly
with your ngers, but do not
over tighten. A secure hold
prevents tool movement.
HINT: Use the 0° by the
Jaw Thumb Screw when
sharpening the FACE
ANGLE. Lock the dial into
position before inserting a
tool. When inserting the tool
make sure it’s face angle is
facing down, facing away
from the Jaw Thumb Screw.

Square Gravers in Quick
Change holders (FIG. F), must
be inserted into the jaws from
the back. DO NOT hold tool by
the Quick Change holder in the
jaw.
Hold Curved Traditional
Graver (FIG. G) as shown.
NOTE: Because of the
tools curve, you will need to
guesstimate the angle needed
to set the face angle.
90 DEGREE SQUARE GRAVER
With the graver’s excess metal
removed (see getting the graver
ready to sharpen, (FIG. G-1)
you are ready to make the face
angle (FIG. G-2). With the tool
mounted, face angle down, and
the TOOL DIAL locked at 0°, set
the POST DIAL at 45°. This is
just an example, you may change
face angles to t your needs. If
you are using a square blank
graver, start your face angle by
using a 260 grit wheel on the
Power Hone. Then nish the face
surface by stepping up to a 600
grit, then a 1200 grit. Once you
have nished the face you will
need only to take these steps
again if the tip becomes severely
damaged. If you’re not using a
Power Hone, shape the face as
close as possible on a bench
grinder and nish with this xture
and a stone.
A 15° heel will be used for this
example (FIG. G-3 & 4). Set the
POST DIAL at 15° and lock it.
Rotate the TOOL DIAL halfway
around or 180°, go from the top
0° setting until the bottom 0°
setting is on top. From the new
0°, tool pointing away from
you, turn dial clockwise, until
it reads 45° and lock. Sharpen
on a ceramic wheel making the
heel about 1/32" long. If you
heel on a 1200 grit wheel, use
the xture and stroke the graver
a couple times without turning
the Power Hone on. After
forming this heel turn the dial
counterclockwise going past the
0° until it reads 45° and lock in
position. Finish the heel on this
side using the same method. It
is important that both heels are
the same size and symmetrical.
MAKING A 120 DEGREE GRAVER FROM A SQUARE GRAVER
Refer to “SHARPENING A 90° GRAVER”, for details. With the
graver’s excess metal removed (FIG. H-1) mount the tool face
angle down in the TOOL DIAL
and lock at 0°. Set the
POST DIAL at 45° (or desired
face angle) and grind the face
(FIG. H-2). Turning the TOOL
DIAL around 180° to reference
0° and change the POST DIAL
to 2-1/2° (halfway between 0°
and 5°) and lock in position.
From reference 0°, rotate dial
clockwise to 30° and grind angle
(FIG. H-3). Make this angle
grind about 1/2" long. Rotate
TOOL DIAL counter clockwise
past reference 0° to 30°, lock
and grind angle (FIG. H-4).
Make this side the same length
as the other side (FIG. H-3).
TIP: To measure how much you
are grinding off, time it or count
while it’s grinding. It may be
necessary to regrind the other
side to make both sides equal.
But it is important that the sides
are equal and symmetrical.
Make the heel (FIG. H-5 & 6)
by changing the POST DIAL
to 15° (or desired heel angle).
The TOOL DIAL is already at
30° left, so make this heel and
rotate TOOL DIAL right, past
reference 0° to 30° and make
the other heel. The 120° graver
is complete.
HOW TO MAKE A 110 DEGREE
& 130 DEGREE OUT OF A
SQUARE GRAVER
Basically, making a 110° or
130° graver is the same as
making a 120° graver, just
change the TOOL DIAL angle
for different side angles.
110° graver (FIG. H-3, 4): The side angle POST DIAL is set at
2-1/2°, but set the TOOL DIAL from reference 0° left 35° and make
one side, then right 35° from reference 0° to make the other side.
130° graver (FIG. H-3, 4): The side angle POST DIAL is set at
2-1/2°, but set the TOOL DIAL from reference 0° left 25° and make
one side, then right 25° from reference 0° to make the other side.
How do you gure this angle setting? The sides of a 90° tool
mounted in a xture, dial set at 0°, are 45° from the wheel. Adding
all angles: 45° + 45° + 90° = 180° (a at plane). Using 180° minus
(desired tool angle) let’s say, 110° = 70°. There are two sides to
the tool, so you divide 70° by 2 which equals 35°, the setting to
make a 110° graver.

CALIBRATION
Step 1: Loosen the two bolts, about a full turn each, in the lower
jaw with a hex wrench. Do not remove.
Step 2: Make sure the bolts are
loose enough that you
can “wiggle” the lower
jaw with your ngers.
Step 3: Insert the small round
calibration pin (included
with the xture) and
slowly start to turn the
thumbscrew to tighten
it into the jaws. While
turning the thumbscrew,
continuously wiggle
the lower jaw. This
will make the lower
jaw “seat” in the
proper location on the
calibration pin.
Step 4: Once you have the
calibration pin seated
and snugged down,
tighten the lower jaw
bolts with the hex
wrench. NOTE: Use
the long end of the
hex wrench in the bolt
head and turn with the
short end to prevent
over tightening. Over
tightening will damage
the xture.
Step 5: Loosen the “DEGREE”
ring with the small hex
wrench until you can
easily turn the degree
ring independently
from the jaw head.
Now, remove the round
calibration pin and
replace it with a square
graver. A GRS GlenSteel
graver will work great.
Step 6: Place a ceramic lap
wheel on your Power
Hone for a smooth at
surface. TIP: If you don’t
have a ceramic lap use a
ne grit diamond wheel and turn it up-side-down and use
the smooth backside. Place the dual angle xture head
on the post stand and position the square graver so that a
side of it is pressed at against the wheel. While holding
the graver at, turn the degree ring and register the 45°
mark to the center line mark and tighten the degree ring
set screw. Now, when you turn the xture head to 0° or
90° the graver is calibrated and in the correct position.
