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 fingers.
Step 3: Insert the small round
calibration pin (included
with the fixture) 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 overtightening.
Overtightening will
damage the fixture.
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 flat
surface. TIP: If you don’t
have a ceramic lap use a
fine grit diamond wheel and turn it up-side-down and use
the smooth backside. Place the dual angle fixture head
on the post stand and position the square graver so that a
side of it is pressed flat against the wheel. While holding
the graver flat, 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 fixture head to 0° or
90° the graver is calibrated and in the correct position.
