Using Accessory Dado Head - Delta 36-477 Instruction Manual

It is necessary when using the moulding cutterhead to
add wood-facing (C) to the face of the rip fence, as
shown in Fig. 135. The wood-facing is attached to the
fence with wood screws through holes which must be
drilled in the fence. 3/4 inch stock is suitable for most
work although an occasional job may require 1 inch fac-
ing.
Position the wood-facing over the cutterhead with the
cutterhead below the surface of the table. Turn the saw
on and raise the cutterhead. The cutterhead will cut its
own groove in the wood-facing. Fig. 135, shows a typi-
cal moulding operation. See accessories page 48 for
molding cutterhead set. NEVER USE MOULDING CUT-
TERHEAD IN A BEVEL POSITION.
IMPORTANT: NEVER RUN THE STOCK BETWEEN THE
FENCE AND THE MOULDING CUTTERHEAD AS
IRREGULAR SHAPED WOOD WILL CAUSE KICKBACK.
IMPORTANT: Special attention should be given the grain direction. Make all cuts in the same
direction as the grain whenever possible.
ALWAYS INSTALL BLADE GUARD AFTER OPERATION IS COMPETE.
IMPORTANT: THE BLADE GUARD AND SPLITTER ASSEMBLY CANNOT BE USED WHEN DADO-
ING OR MOULDING AND MUST BE REMOVED OR SWUNG TO THE REAR OF THE SAW AS
DESCRIBED ON PAGE 15, FIG. 32 AND 33 OF THIS MANUAL.
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. 136.
Various combinations of saws and cutters are used to
cut grooves from 1/8 to 13/16 for use in shelving, mak-
ing joints, tenoning, grooving, etc. The cutters are heav-
ily swaged and must be arranged so that this heavy por-
tion 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 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.
