PRELIMINARY SETUP
Before beginning setup at the table saw or router
table, make sure that the silver micro-adjust knob is
adjusted so that the set screw in the slotted hole on
the red knob is aligned approximately centered on the
engraved line. This is the “home” position and while
not every setup may require this “home” position, it
is a good place to start when moving the IBOX to a
new station. To reset, first loosen the black positioning
lock knob located on the top of the IBOX. Hold the
red knob in place as you rotate the silver micro-adjust
knob until you see the set screw aligned as shown in
Detail 1A. While the black positioning lock knob
is still loose, rotate the red knob to bring the (2) pin
plates together as shown in Detail 1B. You’ll see the
pin plates located just inside the fence cutout. After
adjusting, tighten the black positioning lock
knob, Fig. 1.
Now let’s get set up at your work station. If you are
setting up at the table saw, read the “Setting up at
the Table Saw” section that follows. For the router
table, jump ahead to “Setting up at the Router Table”
beginning on page 4.

SETTING UP AT THE TABLE SAW
1. Install Stack Dado or Box Joint Blade of
Choice
After completing the preliminary setup described on
page 2, unplug your table saw and install your preferred
box joint blade. The INCRA IBOX works with
standard stack dado sets as well as 2-piece reversible
blade box joint sets like those produced by Forrest,
Ridge Carbide and Freud. You can cut delicate 1/8”
box joints using standard 1/8” kerf table saw blades,
but you’ll want to choose a blade that features a flat
ground raker tooth or a special box joint grind like
those from Forrest and Ridge Carbide, Fig 2.
If you are setting up one of the reversible blade sets,
begin with the widest cut profile for the setup that
follows. You can change back to a narrow cut blade
configuration later after the setup is complete. If you
are setting up with a standard stack dado set, any cut
width can be used during setup.
2. Adjust GlideLOCK™ Miter Bar Assembly
Drop the GlideLOCK™ Miter Bar Assembly into
your table saw’s miter slot. Use the left-hand slot for
left tilting saws or the right-hand slot for right tilting
saws. Now adjust the GlideLOCK™ expansion discs
at each end of the bar to adjust the fit for a smooth
glide in your table saw’s miter slot. Turn the fasteners
clockwise to make the glide tighter or counter-
clockwise for a looser glide, Fig. 3. The alignment
plate is factory squared but can be adjusted as required
by loosening the (2) button head fasteners.

3. Attach IBOX to GlideLOCK™ Miter Bar
Assembly
Position the IBOX fence on the GlideLOCK™ Miter
Bar Assembly with the red knob on the left end for left
tilting saws or on the right end for right tilting saws.
Insert the (2) #10-24 x 3/8” button head fasteners
through the slotted holes in the fence and thread
into the holes on the GlideLOCK™ Miter Bar. Don’t
tighten the fasteners just yet. With your table saw
unplugged, raise the dado up about 1/2” then slide
the IBOX so that the cutter is inside the tall notch
in the fence. Carefully slide the IBOX to the left or
right until the blade “kisses” the steel pin plates on
the IBOX, Fig. 4 and Detail 4A. Make sure that
the IBOX is firmly in contact with the alignment plate
on the GlideLOCK™ assembly then tighten the (2)
button head fasteners to secure the fence to the bar.
Lower the blade. NOTE: If you later move the
IBOX to another table saw or your router
table, you will need to reset the miter bar’s
position as described in steps 1-3 above for
the table saw or as described in steps 1-2
on page 4 for the router table.
Continue by skipping ahead to the section
titled “STOCK LEDGES, BLADE GUARDS
AND BACKING BOARD” on page 5.

Assembly
Drop the GlideLOCK™ Miter Bar Assembly
into your router table’s miter slot. Now adjust
the GlideLOCK™ expansion discs at each
end of the bar to adjust the fit for a smooth
glide in your router table’s miter slot. Turn the
fasteners clockwise to make the glide tighter
or counterclockwise for a looser glide, Fig. 5.
The alignment plate is factory squared but can
be re-adjusted as required by loosening the (2)
button head fasteners.

2. Attach IBOX to GlideLOCK™ Miter Bar
Assembly
Position the IBOX fence on the GlideLOCK™ Miter
Bar Assembly with the red knob on the LEFT end of
the IBOX fence. Insert the (2) #10-24 x 3/8” button
head fasteners through the slotted holes in the fence
and thread into the holes on the GlideLOCK™ Miter
Bar. Don’t tighten the fasteners just yet. Slide the
IBOX along the alignment plate until the tall notch on
the fence is centered on your router’s collet, Fig. 6 and
Detail 6A. The center is 9/16” from the edge of the
notch if you would like to use a ruler for the alignment.
Make sure that the IBOX is firmly in contact with
the alignment plate on the GlideLOCK™ Miter Bar
Assembly then tighten the (2) button head fasteners to
secure the fence to the bar. If you move the IBOX to
another router table or your table saw, you will need
to reset the Miter Bar’s position as described in Steps
1-2 above for the router table or steps 1-3 on page 3
for the table saw.

STOCK LEDGES, BLADE GUARDS & BACKING BOARD
In the following steps you’ll add the Stock Ledges, the Blade Guards and the Backing Board. The photos show the
table saw set up but the steps are identical for the router table.
1. Attach Stock Ledges
Insert the (2) #10-32 x 5/16” flat head
Phillips screws through the countersunk
holes in each stock ledge and loosely
thread on the #10-32 rectangular nuts.
The raised rim on the rectangular nuts
should be facing the stock ledge. Slide
the rectangular nuts into the T-slot
on the front of the IBOX fence. For
now, align the ends of the stock ledges
with the wide cutout in the fence and
tighten all (4) fasteners, Fig. 7.

2. Attach Blade Guards
Before attaching the blade guards you’ll need to
identify the component positions. Turn the IBOX
upside down and support it on a couple of 3/4” stock
scraps. Hold the (2) blade guards with the square
cut corners facing the fence so that the low and high
cutouts in the guards match the low and high fence
notches. The cutouts will only align one way, Fig. 8.
Once you have identified which side each blade guard
mounts to, use the included 1/4-20 x 2-1/4” hex bolts
with washers and 1/4-20 thumb nuts to attach the
guards to the T-slots on the fence and Stock Ledges.
Before tightening the thumb nuts, make sure that the
deep cutouts on the guards are aligned with the blade
notch on the fence, Fig. 9.
3. Attach Backing Board & Deflector Shield
Insert (2) #10-32 x 1/2” flat head Phillips screws
into the upper holes on the provided backing board.
Thread on (2) #10-32 rectangular nuts then slide the
nuts into the T-slot on the front face of the IBOX
fence, Fig. 10. Center the backing board on the
fence length and tighten the fasteners. The alternate
holes on the backing board allow you to flip the board
over when needed for a fresh backing surface. Using
the (2) #8 x 1” pan head Phillips wood screws and #8
flat washers, attached the deflector shield to the front
blade guard so that the deflector projects forward over
the cutter. Fig. 11 provides dimensions for making
your own backing boards for future use.

OPERATIONS – CUTTING A BOX JOINT
GET READY…
1. PrepareYour Box-Making Stock
You’ll want to begin by preparing your stock. You’ll need
one piece of scrap stock for a test cut. Mark one edge
of all 4 of the box boards. We’ve used a Sharpie for
clarity, but a pencil mark will work just fine, Fig. 12.
2. Install Your Cutter or Blade of Choice
UNPLUG YOUR TABLE SAW OR ROUTER
TABLE and install the blade or cutter of choice. At
the router table, a 2-flute standard straight bit will
work fine. At your table saw you can use a standard
stack dado, a reversible blade box joint set or a 1/8”
blade with either a flat ground raker tooth or one of
the custom ground box joint blades available, Fig 13.
CAUTION:
DO NOT USE THE IBOX
WITH WOBBLE DADO
SETS OR THIN KERF 3/32”
SAW BLADES!
3. Stock Ledges Apart, Pin Plates Together
Bring the IBOX to your table. Loosen and slide the
blade guard to the side for a clear view. Also loosen
and slide both stock ledges away from the center of
fence to provide clearance during setup. Double check
to make sure that the pin plates are together. If you
need to adjust the pin plates, loosen the positioning
lock knob located on top of the fence and turn the red
knob counterclockwise to bring the pin plates together,
Fig. 14 and Detail 14A.
Whether you are cutting box joints at the table saw or the router table, the set up
routines are the same. We’ll detail the routines in this section with images from
the table saw, but be sure to review the included DVD to see both stations in action.

GET SET…
1. “Kiss” Calibrate
With the positioning lock knob loose, you need to
“kiss” calibrate the IBOX (YOUR TABLE SAW
OR ROUTER TABLE SHOULD STILL BE
UNPLUGGED). To do this, slide the IBOX in your
miter channel to a position adjacent to your cutter.
Now hold the red knob as you rotate the silver
micro-adjust knob to move the pin plates. You’ll want
the pin plates to just touch the blade, Fig. 15 and
Detail 15A. If you are setting up at the router table,
you may need to rotate the cutter by hand to confirm
that the cutter just touches the pin plates. This “kiss”
calibration step zeros the IBOX to the edge of your
cutter. Subsequent adjustments to the pin plates
made by turning the red knob will not alter this initial
calibration.
2. Adjust Pin Plates for Test Cut
With the positioning lock knob still loose, rotate the
red knob clockwise to move the nearest pin plate
about 1/8” or more away from the blade, Fig. 16.
You’ll notice that the pin plates will simultaneously
move away from each other as they move away from
the blade. This is OK. Your “kiss” calibration setting
is automatically retained. Tighten the black
positioning lock knob located on top of the
IBOX fence.
3. Position Stock Ledges
Slide the blade side stock ledge to about 1/8” from the
cutter then re-tighten the fasteners. For reference,
the blade side stock ledge refers to the
stock ledge that is nearest to the cutter
while the pin plate side stock ledge refers
to the stock ledge that is on the other side
of (and nearest to) the pin plates. Slide the
pin plate side stock ledge up to contact the pin plates
and re-tighten the fasteners, Fig. 17. Slide the IBOX
back and forth in the miter slot to make sure that the
blade is clear of both the pin plates and the blade side
stock ledge.

INCRA IBOX OWNER’S MANUAL
©2020 by Taylor Design Group, Inc. All rights reserved.
4. Set Depth of Cut
Set a piece of the wood prepared for your box on the
stock ledge and raise your cutter to a depth of cut
that will cut just slightly through your stock thickness,
Fig. 18. This will produce pins that will protrude only
slightly through the adjacent board when assembled.
These slight protrusions can later be sanded flush.
CAUTION: To avoid contacting the metal
IBox Fence body with your blade, DO NOT
use depth of cut settings greater than 7/8”.
5. Position and Secure Blade Guard
CAUTION: Before replacing your IBOX
blade guard, make sure there is at least 1/8”
clearance between your cutter and the
nearest pin plate, see Fig. 16.
Re-position the blade guard so that the view cutouts
on the front and rear guards align. Sandwich your test
cut board between the front blade guard and the fence
then tighten the black thumb nuts to secure the guard,
Fig. 19. The blade guard also functions as a vertical
stock support, so apply light pressure to hold the
blade guard against the stock as you tighten the thumb
nuts.
6. Make a Test Cut
Stand your test cut piece on end on the blade side
stock ledge between the fence and the blade guard
and slide it up to contact the pin plates. Use a small
wooden handscrew clamp as shown to clamp your
board to the fence as shown, Fig. 20. Plug in your
table saw or router table then make a test cut. Turn
off the motor after completing the cut.
7. Adjust Pin Plates to Fit Test Cut
Loosen the Phillips screws that secure the pin plate
side stock ledge and either one of the thumbnuts
that holds the blade guard. Loosen the positioning
lock knob located on the top of the IBOX fence and
rotate the red knob to open or close the pin plates
until the test cut just made fits over the fingers on
the pin plates (Both pins should be inside the test
cut). You should feel a little friction when you raise
or lower the board but you don’t want it loose. You
can view the pin plates as they are adjusted through
the view cutout in the top of the blade guard, or you
can simply slide the blade guard to the stock ledge on
either side of the blade as shown, Fig. 21. Tighten
the positioning lock knob and the fasteners
that secure the pin plate side stock ledge.
If moved, re-position the blade guard and
re-tighten the thumbnuts. This pin plate
adjustment automatically sets the required distance
between the pins and the blade, so no further
adjustments are required. Now let’s make our box!

TIPS & TECHNIQUES
ADJUSTING THE FIT Fine adjustments to the
fit of a joint can be made by loosening the positioning
lock knob and holding the red knob as you rotate the
silver micro-adjusting knob. Turning the silver knob
clockwise makes the pin larger for a tighter fit, while
turning the knob counterclockwise makes the pin
smaller for a looser fit. (It may be helpful to remember
the phrase, “Righty Tighty, Lefty Loosey”.) Use the laser
cut slit on the silver knob and the engraved marks
on the end of red knob to gauge movement, Fig. 29.
Each mark represents .001” (one thousandth of an
inch). After adjusting, always tighten the positioning
lock knob located on top of the IBOX fence extrusion.
STOCK MARKING TIP Here’s a way to be sure
that your wood is fully seated on the stock ledge before
you begin each cut. Before cutting, stand each of your
boards against the face of the fence and place a pencil
mark across the board along the top of the fence, Fig. 30.
That way, if the board is not fully seated, you’ll easily see
it in comparing the mark to the top of the fence, Fig. 31.
CENTERED JOINERY In theory, just multiplying
your cut width by an odd number should give you
a board width that when cut will have an equal pin
width on the outside edges of 2 of your boards. In
practice it doesn’t work out quite that way. You need
exact measurements of both the pin and groove width
and a degree in higher math for the formula to work
in your favor. Suffice it to say that it is easier just to
make your stock 1/8” to 1/4” wider than the “Kerf x
Odd Number” formula and then trim off the excess
after cutting the joints. If you are interested in a more
creative approach to a centered joint, check out the
“decorative techniques” in the included DVD.
