Mount Back Jaw Casting to Workbench
• Pre-drill holes for mounting screws using template provided. Be sure to drill
holes straight and deep enough to accommodate the full length of the screw.
Use recommended drill sizes only (see template provided).
• It is CRITICAL that the back jaw casting is mounted firmly and accurately to the
workbench surface. NO GAPS between the casting and the workbench should
be present. Use shims as needed. Refer to figure #1 below.
• DO NOT attach the vise to the end grain side of the workbench. By attaching the
vise to the side grain side of the workbench the mounting screw will have a much
stronger hold.
• When attaching the back jaw casting to the workbench, take care to ensure there
is full contact of the casting to the workbench surface before tightening the
mounting screws.
• The vertical portion of the back jaw against the front edge of the workbench and
the horizontal portion of the casting on the underside of the bench must have full
contact with the workbench. Use shims to eliminate any gaps that may be
present.
• Any gaps between the casting and the workbench surface will cause flexing of
the casting when tightened down, which could result in failure of the casting.
Figure 1.
• MOUNTING HARDWARE: Use the #14 x 2-1/2” Counter-Sink Wood Screws (2)
for the front edge mounting holes and the 5/16” x 2-1/2” Lag Screws (2) and the
5/16” Flat Washers (2) for underneath the workbench
