USING ACCESSORY
DADO HEAD
IMPORTANT: THE BLADE GUARD AND SPLITTER
ASSEMBLY CANNOT BE USED WHEN DADOING OR
MOULDING AND MUST BE REMOVED OR SWUNG
TO THE REAR OF THE SAW.
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, as shown in Fig. 69.
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.
70. The saw and cutter overlap is shown in Fig. 71, (A)
being the outside saw, (B) an inside cutter, and (C) a
paper washer or washers which can be 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.
The dado head set (D) Fig. 72, is assembled to the saw
arbor as shown. 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 LOOSE THE OUTSIDE
ARBOR FLANGE, FOR IT WILL BE NEEDED WHEN
REATTACHING A BLADE TO THE UNISAW ARBOR.
ALSO, THE ACCESSORY DADO HEAD SET TABLE
INSERT (E) FIG. 72, MUST BE USED IN PLACE OF THE
STANDARD TABLE INSERT.
