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

⁄

", 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

⁄

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

⁄

" 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

⁄

" greater than the

diameter of the router bit.
Fence Notch Height (E): At least

⁄

" 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

⁄

" dia. through holes

in the auxiliary fence in the locations shown in Fig. 18.

Now, using a

⁄

" 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

⁄

" 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.
