"V" PANELING CUTTER SETS
•Failure to follow these guide-
lines will result in serious per-
sonal injury.
•ALWAYS WEAR ANS I
APPROVED EYE AND EAR
PROTECTION when using this
cutter.
•These cutters should only be
used in a shaper machine, never
in a handheld router.
•Never feed lumber with the rota-
tion of the cutter.
•Follow the safety guidelines set
forth by the manufacturer of the
shaper.
These shaper cutters
have sharp edges. Use
care while removing the
waxy protective coating.
Never turn on the router
with the protective coat-
ing still on the bit.

The "V" Paneling Cutter Set can produce paneling, wainscoting and flooring with
a minimum of setup while producing excellent results. The carbide cutting edges
are precision ground which can make your project accurate and repeatable. The chart
above shows the dimensions of the cutters for each of the three styles. The dimension
noted as “W” is the maximum board thickness which will provide good results. For large
jobs it is recommended that a powerfeeder be used to regulate the feed rate. This will
minimize variances in depth of cut as well as providing a more consistent result.
Step 1. The Tongue Cutter Setup: UNPLUG THE SHAPER!
• Unplug shaper be fore instal l-
in g o r adjusting cutter.
• Keep all guards and anti-kick-
back devices in place.
• Double check bit to insure i t i s
ti ght an d s ecure in spindle.
• Always inspect lumber and other
wood materials for cracks, knots,
or other imperfections that could
cause lumber to kick or shatter
while milling.
Place the Tongue Cutting bit on the spindle and secure tightly. Make sure that the
orientation is as shown in Figure A. Adjust the spindle height so that the bottom
corner of the 45˚ cutter surface is even with the the shapers table top.
Adjust the fence(s) so that they are aligned with the inside edge of the bit. In this
case, the inside edge would be the inner most portion of the slot. Use a good
straight edge across the fence(s). Adjust the fence(s) until the bit barely touches
the straight edge while slowly rotating the spindle by hand.
Use a piece of scrap wood to check if the cutter is at the proper height. If set too
low, the tongue will be set close to the finish side of the board and may cause
weakness and alignment problems later. If set too high, a sharp lip will develop
along the edge of the "V" groove, again causing alignment problems.

When you are satisfied that the spindle height is set correctly, shape all of the project boards that require this
profile along one edge. THINK SAFETY!
Step 2. The Groove Cutting Setup: UNPLUG THE SHAPER!
Remove the Tongue Cutter from the shaper spindle and place the Groove Cutter on the spindle as shown in
Figure B. Change the spindle height until the tongue of the cutter is at the exact same height as the tongue of a
previously shaped board, placed finish side up, on the table.
Adjust the fence(s) as before. This time use the vertical cutter surface located below the tongue (see arrow) as a
reference point to set the fence(s).

Before continuing, check for correct spindle height by shaping a piece of scrap wood. Make sure it is the exact
thickness of the project boards. After shaping, assemble this board to a previously shaped board and carefully
check for offset as in Figure C.
Figure C.
If you find that your offset is as illustrated in Figure C, the spindle is set too low. If the bit is set too high the newly
shaped board will be lower than the board with the tongue. Repeat the Tongue alignment as stated at the begin
ning of Step 2. If the boards are uneven on one side only, the boards are not the same thickness.
Figure D.
Figure D shows finished project with the outside boards having plain edges. Please note that setting the fences
as described above, you should expect a loss of
