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. 136). 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.
137. The saw and cutter overlap is shown in Fig. 138, (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. 139, to the saw
arbor. IMPORTANT: 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. Also, the
accessory dado head table insert (E) Fig. 139, must be
used in place of the standard table insert.
