Using Accessory Dado Head - Delta 36-444 Instruction Manual

USING ACCESSORY
DADO HEAD
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. 68.
Various combinations of saws and cutters are used to
cut grooves from 1/8" to 13/16" wide 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. 69. The saw and cutter overlap is shown in Fig. 70,
(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. 71, is assembled to the saw
arbor in the same manner as the saw blade. The guard,
splitter, and anti-kickback finger assembly cannot be
used when dadoing and must be removed from the saw.
In place of the guard, auxiliary jigs or fixtures and push
sticks and featherboards should be used. Also, the
accessory dado head table insert (E) Fig. 71, must be
used in place of the standard table insert. Fig. 72, shows a
typical dado operation using the miter gage as a guide.
WARNING: NEVER USE THE DADO HEAD IN A
BEVEL POSITION.
IMPORTANT: ALWAYS REINSTALL BLADE GUARD
AFTER OPERATION IS COMPLETE.
