Rout the test groove
Rout the test groove
Turn the router on, and using a good rubber soled push
block, cut a groove along the entire length of the board. See
Fig. 19. Now turn the stock end for end with the groove still
face down and make a second pass over the router bit. The
second pass should widen the groove slightly (unless you are
already perfectly centered). Make sure you have turned the
stock end for end before making the second pass. (This
places the center mark at the back of the board.)
Fine-tune the fence position
With the router unplugged, turn the bit to its widest cut
angle (viewed from the infeed side of the router table). Place
the board against the fence with the router bit just inside the
test groove cut. There should be a small gap between the
edge of the bit and one side of the groove. See Fig. 20.
Now all that is needed is to micro adjust the fence position so
that with the board against the fence, the bit is in the center
of the groove. Use the Ultra Lite’s micro adjuster to move the
fence until there appears to be an equal gap on both sides of
the router bit. See Fig. 21. Once the bit is in the middle of
the groove, make sure to lock the carriage clamp in place.

Once you have successfully found the center of the
board’s width with your router bit, slide the template you
have selected for joinery into one of the scale slots on your
Incra Jig’s carriage. This must always be done with the
carriage still locked at the center position you just found. Slide
the template until the suggested center cut on the template is
directly under the hairline cursor. You’ll find the suggested
center cut listed under the diagram of each template pattern
shown above. You are now ready to cut the joint.

With the jig still locked at the
center of your board, slide the
template in to position the “center
cut” under the hairline cursor
In order to save wood when centering the bit on
wide stock, just leave one of the boards you’ve cut for
your box about an inch to two longer than necessary. Clamp
this piece to your Right Angle Fixture as shown in Fig. 23
and make the test cuts described in Step 3 through the end
of the board, flipping the piece edge for edge before making
the second cut. After you are centered, just crosscut the
extra length off of the board’s end.
