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. 61). 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 in Fig. 62. The saw and cutter overlap is shown in
Fig. 63, (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. 64, to the saw arbor.
NOTE: The outside arbor flange cannot 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. 64, 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. 65 shows a typical dado operation using the miter
gauge as a guide.
Never use the dado head in a bevel
position.
Always install the blade guard after the
operation is completed.
