The blade guard and splitter assembly
cannot be used when dadoing or moulding. It must
be removed as described in “USING AN ACCESSORY
MOULDING CUTTERHEAD” section.
Use pushsticks, hold-downs, jigs, fixtures,
or featherboards to help guide and control the workpiece
when the guard cannot be used.
The accessory dado head set table insert (E)
FIG. 67 must be used in place of the standard table insert.

USING AUXILIARY WOOD FACING
Add a wood facing (A) Fig. 64 to one or both sides of the
rip fence when you perform special operations (moulding
cutterhead, etc.). Depending on the fence, attach the wood
facing o the fence either with wood screws through holes
drilled in the fence, or with two clamps. For most work, 3/4”
stock is suitable, although an occasional job may require 1”
facing.
Dadoing is cutting a rabbet or wide groove into the
workpiece. Most dado head sets are made up of two
outside saws and four or five inside cutters, (Fig. 64).
Various combinations of saws and cutters are used to cut
grooves from 1/8" to 13/16" for use in shelving, making
joints, tenoning, grooving, etc. The cutters are heavily
swaged and must be arranged so that the teeth do not hit
each other during rotation. The heavy portion of the cutters
should fall in the gullets of the outside saws (Fig. 65). The
saw and cutter overlap is shown in Fig. 66 - (A) being the
outside saw, (B) an inside cutter, and (C) a paper washer
or washers, used as needed to control the exact width of
groove. A 1/4"groove is cut by using the two outside saws.
Position the teeth of the saws so that the raker on one saw
is beside the cutting teeth on the other saw.

Do not attempt to stack dado blades thicker than 13/16” (20mm) Do not use dado blades larger than 8”
(200mm) in diameter.
Attach the dado head set (D) Fig. 63 to the saw arbor.
NOTE: If the arbor nut does not fully engage the thread on
the arbor, remove the outside arbor flange and tighten the
arbor nut against the dado head set body. Do not lose the
outside arbor flange. It will be needed when reattaching a
blade to the arbor.
Never use the dado head in a bevel position.
Always install the blade guard and standard table insert after the operation is complete.
