USE

OF

THE DADO

HEAD

 

 

 

The dado saw (or head) is a special set of blades for cutting

7

grooves and dados. The Craftsman 8-inch Kromedge Dado

Set may be purchased at any Sears Retail Store or Catalog

Order

House. The complete

head consists of

two outside

blades 1/8-inch thick, six chipper blades 1/8-inch thick

 

and paper washers for 1/16-inch width adjustments. With

 

these blades, grooves may be made in widths of 1/8-inch,

 

1/4-inch, and additional widths in steps increased by

 

1/16-inch each, up to a maximum of 13/16-inch. Outside

 

blades may be used alone, but chippers cannot be used

 

alone. When the maximum 13/16-inch width of dado is

 

used on the motor shaft, the outside loose collar must not

 

be used. The width of the dado can be reduced while using

 

the loose collar and two or more passes may be made with

 

the work to obtain the desired width of cut. Whenever two

 

or more chippers are used, the cutting ends should be

Figure 35

staggered as evenly as possible around the circumference.

 

Fractional adjustments in thickness of the head can be

 

made by using paper washers between the

outside blades

 

and chippers.

 

 

 

 

 

 

 

 

 

Dado

operations

are

essentially the

same as

those

 

operations

using

a standard

saw

blade--but

the

dado

 

head takes a bigger bite, therefore, the work-piece should

 

be held more firmly. When a groove wider than the dado

 

head is needed, make two or more passes, with cuts spaced

 

to overlap a trifle. Dado work is performed in the cross-cut

 

position. Ploughing is done in the ripping position. If the

 

rip or plough position is used, the saw guard and anti-

 

kickback pawl assembly should be adjusted as described

 

in the paragraph "RIPPING". Rabbeting is done with the

 

motor shaft in a vertical position. (See figure 35.) When

 

rabbeting, the motor is indexed 90 ° to the vertical position

 

so the blades are between the table top and motor, and

 

the yoke is indexed 90 ° clockwise and locked. The saw

 

is moved back on the radial arm and locked to the arm

 

when the amount of the blade extending forward of the

 

fence

is equal to

the

depth

of

the

rabbet

desired.

If the

of the rabbet is large,

MOLDING OR SHAPING

This work is performed with Craftsman Molding Cutter Heads, and a set of cutters depending on the type of mold- ing cut desired. The saw is positioned in the same manner as that described for rabbeting. (See figure 36.) Since the position of the cutters can be adjusted with respect to the

fence and table top, any or all of the cutter shapes may be used.

The Molding Cutter Guard should be used with Molding Cutter Head.

REMOVAL AND INSTALLATION OF

MANUAL BRAKE ASSEMBLY

Prior to performing any operation that requires the use of the motor shaft opposite the saw blade end (routing, dove- tailing, boring, sanding, etc.), it will be necessary to remove the manual broke assembly to expose the end of the shaft.

This is accomplished as follows: (See figure 37.)

1.Remove the guard assembly, saw blade and both cottars.

2.Remove two 1/4-20 x 7!16-inch, hex-head screws to free the brake housing from the motor.

3.Pull the brake housing off end of motor housing, leaving the brake shoe and spring in the brake housing.

4.Hold the motor shaft (at saw end) with the shaft wrench and remove the brake drum from motor shaft with the arbor wrench. (This end of motor shaft has right-hand threads.)

5.Install a chuck or other accessory as required, on end of motor shaft and tighten it firmly on the threads. The motor shaft should be held with the shaft wrench at saw

end of shaft while tightening the chuck or other accessory.

6.When finished with the particular operation being per- formed, install the manual brake assembly by reversing

the preceding removal procedure. (See figure 37.)

7.Install saw blade and guard assembly.
