GRS Low Profile Ball Vise
For Engraving And Jewelry Making #003-615
BALL SWIVEL
TENSION SCREW
Maintenance
Based on usage, open jaws fully and clean any dirt
and metal pieces from the threads. After cleaning,
apply a small amount of light oil to the threads.
Jaw Thread Replacement
Over tightening the jaws will cause wear and damage
to the threads. If jaws become loose, replace with kit
#003-627. Remove jaws by opening wide until they
come off the jaw screw. The thread pin (A) is located
on the under side of each jaw. Before removing
pins locate the left hand pin, marked “L”. Replace it
with the same. Apply a small amount of grease to the
O-rings before installing them. Start the jaws threads
at the same time when replacing them. Hold each
jaw in position (Fig. 1) and turn the jaw screw. An
extra pair of hands makes this easier, or place a large
rubber band over the jaws.
Optional Turntable Base For Microscope Work
To use the turntable base, lock the vise by tightening
the swivel tension screw until the ball will not turn.
The turntable now becomes your rotation, allowing
you to adjust the work’s center of rotation into the
eld of view of the microscope. Align the center of the
turntable with the center of the microscope (Fig. 2).
Change working views by repositioning the vise.
