The EAS 2421 Vee Fixture is used for
measuring cylindrical (O.D.) parts up to
approximately 1"/25mm in diameter that
are too small to be accommodated in the
gage’s “Closed” probe position mode. The
fixture consists of two parts — a Top Plate
for holding the PocketSurf unit and a
Bottom Plate with a Vee for holding the
workpiece.
With the Vee Fixture, the probe is used in
its 90° position. Either a General Purpose
Probe or an optional Parallel Chisel Probe
(which is recommended for cylindrical
parts less than ¼"/6,35mm in diameter)
can be used.
EAS-2421 VEE Fixture
1. Mount the Pocket Surf unit,
with the probe in its 90°
position, to the fixture’s
Top Plate using the captive
screw in the Top Plate.
The screw mates with the
tapped hole in the bottom
of PocketSurf housing.
2. Place the cylindrical
workpiece to be measured
across the Vee on the
Bottom Plate.
3. Position the Top Plate,
with the Pocket Surf unit
attached to it, on the
fixture’s Bottom Plate so
that the Top Plate’s two
legs rest in the recesses
in the Bottom Plate and the
probe stylus and skid rest
on the top of the workpiece.
4. Use the fixture’s
Adjustment Screw to raise
or lower the Top Plate so
that the Reference Line on
the Probe Mounting Block
is parallel to the bottom of
the Pocket Surf housing
(as outlined in the
Gage
Operation
section).
When correctly adjusted,
tighten the knurled Lock Nut
on the Adjustment Screw to
secure the setup.
