Step 5: Mounting the router to the Insert Plate Step 6: Leveling the Insert Plate to the Opening
Step 7: Installing & Leveling the Reducing Rings
Step 8: Installing the Starting Pin
Begin by locating the 3/8” phenolic Insert Plate (#1) and placing it face
down on your workbench. The Kreg Logo on the Insert Plate should not
be visible. Take the clear Plastic Template and place the edge marked
“FRONT” towards the front edge of the insert plate. Align the template
so that the Start Pin Hole marking and the bull’s-eye line up perfectly with
the Insert Plate. Once positioned correctly, securely tape the template into
place.
In a later step, you will be duplicating your router’s base plate holes into
your Insert Plate so that you can connect your router directly to the Insert
Plate. First, you must determine the correct size of the holes to drill in
your Insert Plate. Remove the base plate from your router and fi nd the bit
that fi ts just inside of the base plate’s holes.
Now, center your base plate on the concentric rings of the bull’s-eye
template. Keep in mind what position you want the router in when it’s
suspended from the table and make certain the base is rotated to refl ect
that position. For instance, it’s best to have the lock on the router base,
and the controls on the router motor, toward the front of the table, or as
easily accessible as possible.
Note: If your router is equipped with a built-in lift system, you will need to
drill the appropriate holes through the insert plate at this time to gain access
to the system and make adjustments to the bit depth of your router after
it’s been mounted to the insert plate. Once again, use your router base
plate to choose the appropriate size drill bit needed for these holes. VERY
IMPORTANT – When positioning your base plate for drilling, make sure that
none of the holes you are about to drill line up over the pre-drilled Start Pin
Hole in the insert plate.
Once you have the base plate from your router aligned where you want it
on the template, use heavy duty masking tape to secure your base plate
to the bull’s-eye template. Tape on at least four sides of your base plate to
ensure a strong and secure hold.
Whether you use a drill press or hand drill, we recommend you place a
scrap piece of wood under the insert plate. This will reduce blowouts as
you drill through the insert plate. It’s easiest to do this operation on a drill
press so the holes are perfectly square to the insert. If you must drill it by
hand, be careful to keep the holes straight. Before drilling, securely clamp
the insert plate to your bench or drill press to hold it secure and reduce the
chance of the material moving as you drill.
After the holes are drilled, remove the base plate & template. Flip the
insert plate over and use an 82 degree countersink bit to countersink each
hole so the head of the screws sit at fl ush or slightly below the plate’s
surface when tightened down. Be very careful not to over drill these holes,
as their depth will directly affect the quality of your routing surface.
The unique design of the Precision Insert Plate Levelers (#8) and
adjustable leveling screw system applies pressure to both sides of
the Insert plate so that – once locked in – the Insert Plate stays fl ush
regardless of the weight applied. The 8 Leveling Screws and 4 Lock-
Down screws work together to keep the Insert Plate fl ush with the router
table surface at all times.
Set the eight ¼-20 x 1-½” Cup Point Socket Set Screws (#10) to
aproximately the same height and lay the Insert Plate into the opening.
The Insert Plate should be resting on the eight adjustable Set Screws.
Using the 1/8” Allen Wrench (included), adjust the set screws from the
bottom side of the Insert Plate, being careful to adjust each screw the
same distance as the other. Adjust the Insert Plate as close as possible
to fl ush with the surface of the router table top and run your fi nger along
the perimeter of the Insert Plate to check that all edges are fl ush with the
router table top.
Thread the four ¼-20 x 1-3/4” Phillips Flat Head Machine Screw (#12)
(Lock-Down Screws) through the countersunk holes into the center hole
on each leveler and snug down. Run your fi nger along the perimeter
of the Insert Plate again to check that all edges are fl ush with the router
table top. Some loosening or tightening of the lock down screws might be
necessary to help adjust the reducing ring and hold it securely in place.
Note: We recommend adjusting both reducing rings at this time. This will
save time later as you change which reducing ring you want to use, and
also reduces the possibility of losing the second set of small Flat Point
Socket Set Screws. After you have leveled one reducing ring, remove it
and level the other.
Insert three 8-32 x ¼” Flat Point Socket Set Screws (#13) into reducing
ring’s threaded holes, using a 5/64 Allen Wrench as shown. Place the
reducing ring into the Insert Plate opening and rotate counter-clockwise
until the set screws fall into the corresponding holes. Adjust the set
screws until the reducing ring is perfectly level with the Insert Plate.
Secure the reducing ring by threading the 8-32 x 5/16” Phillips Flat Head
Machine Screws (#14) into their holes and tightening snuggly.
As you tighten down the reducing ring, some additional adjustment
under tension may be necessary. Adjust each set screw as needed to
bring the reducing ring fl ush with the insert plate. Some loosening or
tightening of the lock down screws might be necessary to help adjust
the reducing ring and hold it securely in place. By leveling the reducing
rings while force is applied in both directions, the rings will stay fl ush
regardless of the weight applied, providing a more level and secure work
surface.
Thread the ¼-20 x ¾” Cut Point Socket Set Screw into the bottom of the
Brass Starting Pin using a fl at head screw driver and a 1/8” allen wrench,
until the two are secured tightly together. Insert the Starting Pin assembly
into the Insert Plate Start Pin Hole and thread in until tight.

PLEASE NOTE:
All routers are different. When aligning the router’s base plate to
the bull’s-eye template and Insert Plate, take into consideration all of
the controls you will need access to when the router is suspended
below the plate during operation. Plan your installation completely
and adjust the router orientation accordingly. The router handles do
not need to be square with the table or plate for proper operation, so
easy access to the on/off switch and other controls should be your
#1 priority when attaching the router to the Insert Plate.
