Glendo GRS 003-570 Instructions

Dual Angle Sharpening Fixture INSTRUCTIONS
PART #003-570
Set both dials at 0° to the register marks.
Then, slide the fixture onto the base post
and hold it out in front of you. Position the
fixture 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 fixture
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 modification to fit a hand handle or power handpiece, or
just shortened to fit your personal
needs. GRS Tools does offer
gravers that are already modified
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 first, 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 fingers, 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.
