Delta SHOPMASTER SM200L Instruction Manual page 22

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. 44A). 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. 45. The
saw and cutter overlap is shown in Fig. 46, (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. 47, to the saw arbor.
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 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. 47, 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. AUXILIARY JIGS, FIXTURES,
PUSH STICKS AND FEATHER BOARDS SHOULD
ALSO BE USED.
3. Fig. 48, shows a typical dado operation using the miter
gage as a guide.
NEVER USE THE DADO HEAD IN A
BEVEL POSITION.
