1. Dadoing is cutting a rabbet or wide groove into the
work. Most dado head sets are made up of two outside
saws and four or five inside cutters, (Fig. 53). 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 this heavy portion
falls in the gullets of the outside saws, as shown inFig.
54. The saw and cutter overlap is shown in Fig. 55, (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. The teeth of the saws should be
positioned so that the raker on one saw is beside the
cutting teeth on the other saw.
2. Attach the dado head set (D) Fig. 56, to the saw arbor.
NOTE: THE OUTSIDE ARBOR FLANGE CAN NOT BE
USED WITH THE DADO HEAD SET, 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.
THE ACCESSORY DADO HEAD SET
TABLE INSERT (E) FIG. 56, MUST BE
USED IN PLACE OF THE STANDARD TABLE INSERT.
THE BLADE GUARD AND SPLITTER
ASSEMBLY CANNOT BE USED WHEN DADOING AND
MUST BE REMOVED OR SWUNG TO THE REAR OF
THE SAW AS EXPLAINED PREVIOUSLY IN THIS
MANUAL. AUXILIARY JIGS, FIXTURES, PUSH STICKS
AND FEATHER BOARDS SHOULD ALSO BE USED.
3. Fig. 57, shows a typical dado operation using the miter
gage as a guide.
NEVER USE THE DADO HEAD IN A
BEVEL POSITION.
ALWAYS INSTALL BLADE GUARD
AFTER OPERATION IS COMPLETED.

USING AUXILIARY WOOD FACINGON RIP FENCE
When performing special cutting operations – and that
operation may cause the cutting implement to contact
the fence – it is necessary to add a wood facing (A) Fig.
58, to one side of the rip fence as shown. The wood
facing is attached to the fence with wood screws
through holes drilled in the fence. 3/4-inch stock is
suitable for most work, although an occasional job may
require one-inch facing.
