Front Vise
Table 1: Calculating jaw height.
Once you have determined the proportions of your jaws, you
can cut them to size, unless you are making a full-width end
vise. In this case, cut the length of the jaws 1
"
oversize to allow
for a
1
/
2
"
trimming allowance on each end. This will be trimmed
later (
step 16
).
If a spacer will be used, it should equal the length and width
of the carriage. With the carriage fl ush to the edges of the
spacer, spot the carriage mounting holes into the spacer and
drill these as
1
/
2
"
dia. clearance holes.
Instructions
1. Carefully fold the appropriate template along one of the
dotted lines so the distance from the fold to the top edge
of the guide rods matches your final throat calculation.
The lowest line represents a throat of 2
"
(plus a
1
/
16
"
planing allowance). Lines are further spaced
1
/
8
"
apart
for your convenience.
2. Cut two small windows in the template (at the top and
bottom of the center line) as indicated.
3. Mark a vertical center line on what will become the
clamping face of the
rear
jaw. Place the template on the
clamping face of the rear jaw, with the fold flush to the
top edge and the center line on the template lining up
with the center line of your jaw. Using a sharp punch,
mark the centers of the three holes. (
Note:
If your jaw
configuration matches that of
Figure 2
, you will have to
temporarily affix the rear
half
jaw to the underside of
the bench before performing this operation.
) Also mark
the centers for any hardware you intend to use to mount
the jaw to the bench.
4. For the Large Front Vise (70G08.02)
only
: On the
clamping face of the
rear
jaw, drill two counterbores for
the guide rod support collets using the guide rod center
marks. Use a 2
5
/
16
"
saw tooth bit or an expansion bit, to a
depth of
9
/
16
"
. (
Note:
The Regular Front Vise (70G08.01)
does not come with support collets.
)
5. On a drill press drill three
1
/
8
"
pilot holes through the
rear
jaw where the guide rod and lead screw centers
are located. At this time you should also drill and
counterbore for any hardware required for mounting the
rear jaw to your bench. If using lag screws, remember to
make the counterbore diameter large enough to accept a
washer and the appropriate drive socket. Do
not
attach
the rear jaw at this time.
6. Clamp the front and rear jaws together, aligned as they
will be once they are fully assembled. Ensure that what
will be the top and ends are flush.
Note:
If your jaw
configuration matches that of
Figure 2
, the rear half
jaw will have to be offset from the top of the front jaw
accordingly.
Place the jaws in a drill press and, picking
up on the
1
/
8
"
pilot holes from the
rear face
of the
rear
jaw, bore the guide rod and the lead screw clearance
holes through both pieces. The table below shows the
clearance hole diameters. These diameters have been
rounded off to the nearest
1
/
8
"
oversize. To reduce
tear-out, support the bottom jaw with a piece of scrap.
