inch wide can be cut. Outside blades can be used alone,
chippers cannot.
A dado insert (part 9-2212, fig. 4) must be used to re-
place the standard table insert. Whenever two or more
chippers are used, stagger the swaged ends as evenly as
possible around the circumference. Fractional adjust-
ments in thickness of the head can be made by using
paper washers between the outside blades and chippers.
Dado head operations are much
the same as those with a standard
blade _ but the dado head takes
a bigger bite, so that workpiece
should be held more firmly. It is
good practice to use a hold-down
jig like the one illustrated.
When a groove wider than the _-
dado head is needed, make two
or more passes. Best method is
to use a notched stop block to po-
sition each successive cut. Block
is fastened to edge of table where
it can be used to position work
before starting the cut; but in such a position that it will
not contact work during the cutting operation. Space
cuts so that they overlap a trifle.
