MicroBlock Ball Vise For Engraving and Jewelry Making
INSTRUCTIONS • #003-683 & #003-684
Maintenance
Based on usage, open jaws fully and clean dirt and metal pieces from
the threads. After cleaning, apply a small amount of light oil to threads.
Jaw Thread Replacement
Overtightening the jaws will cause wear and damage to the threads.
If jaws become loose, replace with kit #003-629. Remove the jaws by
opening them as wide as possible until they come off the end of the jaw
screw (FIG. 1). The jaw thread pin is located on the underside of each
jaw. NOTE: Before removing pins, locate the one with the “L”. This is
the left hand thread pin and will need to be replaced with the same.
Apply a small amount of synthetic grease (included in kit) to the O-ring
and jaw screw before installing them. Lift the jaw screw out of the yoke
and replace it. Note which side the left hand thread is on. Grease the
threads and yoke well.
Start the jaw threads at the same time when replacing them (FIG. 2).
Hold each jaw in position and turn the jaw screw to close them. Either a
large rubber band or a second person is useful to hold the jaws against
the thread while the jaw screw is turned. If the jaws don’t meet at the
same time in the center, remove them and try starting the threads at the
same time again.
Rotational Lock Replacement
The LOCK or DRAG PIN is subject to wear by design and may need
replacement after extended use. Simply remove the ball swivel tension
screw with hex wrench. The Spring and Lock Pin should follow (FIG. 3).
If not, turn the ball until they fall out. Replace the Lock Pin (order
#003-307), Spring and Tension Screw.
Thread Pin Replacement Kit #003-629
Includes Jaw Screw, Left and Right Thread Pins, O-Rings, and Tube
of Synthetic Grease.
520 Attachment Set #003-520
Included with MicroBlock Ball Vise #003-684.
Jaw Screw
The GRS MicroBlock will provide many
years of trouble-free service. It is extremely
rugged in construction, yet is relatively
simple and easy to maintain. Required
lubrication is minimal.
The jaws are drilled to accept engraving
block attachments. The MicroBlock
includes six socket head screws,
which can be used to secure special
items or fixtures. GRS offers the 520
Attachment Set (#003-520) that
includes storage for the pins that come
with the block.
