USING A DADO BLADE SET (OPTIONAL) AND DADO
INSERT
Dadoing is cutting a rabbet or a wide groove into the work. Most
dado head sets are made up of two outside blades and four or five
inside cutters, as shown in Fig. 25. Various combination of blades
and cutters are used to cut grooves from 1/8 in. to 13/16 in. for use
in shelving, making joints, tenoning, grooving, ect. The cutters are
heavily swaged and must be arranged so that this heavy portion falls
in the gullet of the outside blades, as shown in Fig. 26. The saw and
cutter overlap is shown in Fig.26, (A) being the outside blade, (B)
being the inside cutter, and (C) being a paper washer which can be
used as needed to control the exact width of groove. A 1/4 in. groove
is cut by using the two outside blades. The teeth of the blades should
be positioned so that the raker on one saw is beside the cutting teeth
on the other saw. The dado head set is assembled to the saw arbor
in the same manner as the saw blade. The blade guard and anti-
kickback finger assemblies can not be used when dadoing operations
and must be removed from the saw. The riving knife must be set in
the “down” position and the included dado table insert must be used
in place of the standard table insert. Never use the dado head in a
bevel position unless you make your own dado insert! Always rein-
stall blade guard and anti-kickback finger assemblies after operation
is complete!
