CHANGING THE TOP VISE JAWS
To change the top vise jaw unscrew the painted key-clamping knob a few turns. Unscrew the large
knurled knob located below the painted key-clamping knob a few turns. Slide out the top vise jaw. Look
for key cutting chips and brush them away before reinstalling the top vise jaw. Reinstall the top vise jaw in
the reverse order.
NOTE:
When reinstalling the top vise jaw you should push on the face of the top vise jaw and hold it
against the vertical step on the bottom vise jaw. By doing this you will insure that the top vise jaw is
installed perfectly parallel to the bottom vise jaw. This is especially important when using the face of the
top vise jaw as a reference surface when cutting keys like Ford double-sided and when using the step jaw
Especially when cutting Medeco keys.
Always change both vise jaws to standard or step jaw configuration. If you change only one your depth
will be off either plus .037” or minus .037”. See figure 3 below
Check the knurled knobs securing the top vise jaws for tightness often and recheck the parallelism of the
top vise jaws- especially when using the step vise jaw configuration and when cutting keys such as Ford
double-sided.
TOP VISE JAW REPLACEMENT
Either top vise jaw may be replaced at any time. You do not have to buy top vise jaws in pairs. Inspect
your top vise jaws for uneven clamping and referencing surfaces. Replace when worn. Accelerated wear
occurs when you clamp double-sided steel keys such as Volkswagen. Clamping pre 1984- ½ Ford doubled
sided keys too far to the right into the vise jaw causes wear to the left edges of both the top and bottom vise
jaws. The damage is due to the “wedged” shaped milling of these keys as you approach the bow of the key.
