Testing the Installation and
Installing the Apron
Release the jaw and test the mechanism to ensure the
vise can travel fully without excessive binding. (Note
that a bit of drag between the jaw and the workbench
is acceptable.) If the vise binds, you can remove the
jaw and lightly plane down the surface that contacts
the bench top, or install shims between the jaw and the
mechanism. Alternatively, you could lightly plane the
edge of the bench.
Note:
Since the half nut is usually activated by gravity,
the quick-release mechanism will not work while the
bench is upside down. To test the motion of the vise, you
will have to manually pull the half nut out of engagement.
Flip the workbench back to its upright position. Back
the vise off slightly (one or two turns) and install the
apron so that the jaw clamps up to the apron before the
vise uses its full travel.
Finishing Touches
Plane the front face of the jaw so that it is fl ush with the
apron, and plane the top surface of the jaw and apron so
that it is fl ush with the workbench top.
Apply the desired fi nish to the jaw and apron.
Use
This quick-release sliding tail vise is a fairly simple
device. Workpieces can be clamped between the jaw
and the apron; however, it is more common to clamp
workpieces between bench dogs, either on the top of the
workbench or along the front of the bench, if appropriate
dog holes have been drilled in the jaw/apron.
A novel feature of this vise is the quick-release half nut.
To actuate, fl ip the quick-release lever from horizontal
to vertical, as shown in
Figure 11
. (You may need to
rotate the handle to release the threads.)
Caution:
Do not
release the half nut when the vise
is loaded.
To re-engage the half nut, simply fl ip the lever back to
horizontal. If the threads in the half nut are not aligned
with those on the main screw, the lever may not return
immediately to horizontal. If this is the case, you can
align the threads by rotating the main screw; this will, in
turn, force the quick-release spring to nudge the half nut
into place, and snap the quick-release lever to horizontal.
Care and Maintenance
The vise comes fully lubricated; however, it will need
periodic cleaning and lubrication. White grease on the
main screw will ensure smooth operation, and a light
oiling of the half nut will keep this component moving
freely. The guide rods do not require lubrication; they
have a surface treatment that is self-lubricating and
prevents rust.
Note: Do not
use silicone-based lubricants on the
main screw.
