X-Y Positioner for the Drill Press
Used at your drill press, your new INCRA Jig and INCRA
PRO Fence System are the ultimate in X-Y positioning
control. You can quickly and accurately locate and drill
any pattern of holes by simply moving the INCRA Jig
and the INCRA Stop to the desired settings. A cribbage
board is a good example of a project that requires this
ability. And since you can locate any hole to within a few
thousandths of an inch, you will find this technique great
for making perfect dowel joints.
Mounting an Auxiliary Fence to
Your INCRA PRO Fence
If you should desire to use a router bit with a diameter
greater than
3
⁄
4
", you must first mount a wooden auxiliary
fence to your INCRA PRO Fence. The following
information should help in determining the dimensions of
the auxiliary fence, see Fig. 17.
Thickness (A): The thickness of the auxiliary fence should
be 1
1
⁄
2
times the diameter of the router bit you plan to use.
(Example: To use a 1" diameter router bit, your auxiliary
fence should be 1
1
⁄
2
" thick.)
Height (B): The height of the auxiliary fence should be 3"
minimum.
Length (C): Cut the length of the auxiliary fence to match
the length of your INCRA PRO Fence, either 18" or 28".
Fence Notch Width (D): At least
1
⁄
4
" greater than the
diameter of the router bit.
Fence Notch Height (E): At least
1
⁄
4
" greater than the
maximum depth of cut you plan to use with the router bit.
To mount the auxiliary fence to your INCRA PRO
Fence, you will need (2) #8
–
32 machine screws, (2) #8
flat washers and (2) #8
–
32 hex nuts. The length of the
machine screws should be slightly less than the thickness
of the auxiliary fence. Drill two
3
⁄
16
" dia. through holes
in the auxiliary fence in the locations shown in Fig. 18.
Now, using a
1
⁄
2
" diameter drill bit, counterbore the hole
locations.
Note: Adjust the depth of the counterbore so that the
screw, when installed in the counter bore with the #8 flat
washer, extends slightly less than
3
⁄
4
" through the back of
the auxiliary fence. Loosely attach the #8
–
32 hex nuts to
the screws then slide the hex nuts into the T-slot located
on the front face of the INCRA PRO Fence. Tighten the
machine screws to secure the auxiliary fence in place.
For short term auxiliary fence applications, you
might find it convenient to use an aggressive
double-faced tape to attach the auxiliary fence. We
recommend #ST501 manufactured by SpecTape of Texas.
Call 1-800-442-1338 for your nearest distributor, or check
with your INCRA dealer.
Do not use standard double-faced
carpet tape.
