USE OF THE DADO HEAD

The dado saw (or head) i s a special set of blodes for cut-
ting grooves and dodos. Craftsnian 8-inch Kromedge Dado
Order House. The head consists of two outside blades
washers for 1/16-inch width adiustments. With these blades,
grooves of 118-inch, l/4-inch and, additional widths in-
1
creased in steps of
wide, can be cut. Outside blades may be used alone, chip-
pers cannot be used alone.
When using the maximum width of dado of I-inch on the
motor shaft, the loose collars must not be used. The width
of the dado may be reduced while using the loose collar
and two or more passes made with the work to obtain the
desired width of cut. Whenever two or more chippers are
used, stagger the cutting ends as evenly as possible around
the circumference.
Fractional adjustments in thickness of the head may be
made by using paper washers between outside blades nnd
chippers. Dado head operations are essentially the same
as those with a standard blade. However, the dado head
takes a bigger bite, so the work-piece should be held more
firmly. When a groove wider than the dado head is needed,
make two or more passes. Space the cuts so they overlap a
trifle. Dado work i s performed in the crosscut position.

ROUTING AND DOVETAII-ING
Routing and dovetailing are accomplished with the motor
indexed and locked from horizontal, except the exter-
nally threaded stub end (opposite the normal blade end)
is between the motor and table top. The following chucks
will mate with this external 1/2-20 thread. (See figure 46.)

The following routers and dovetails ore recommended:
1 /8-inch router

/4-inch router
1 /2-inch router
Routing may be performed by either moving the work with

a stotionury router or
and moving the router. Always approach the router b i t
from the lefi-hand side of the saw.
