Sanding; Stabilizing Washers For Thin Blades - Sears Craftsman 113.29943 Owner's Manual

3. A dado insert must be used to replace the standard table
insert. When using a full 13/16*inch dado set, the arbor
cannot be tilted to 45 degrees without touching the
insert. Do not attempt to operate in this position. Also
when the dado is set for the maximum depth of cut
(1-3/8-1nches), be sure to spinthe blade by hand before
turning on the motor to make sure the blade does not
strike the dado insert. Whenever two or more chippers
are used, stagger the swaged ends 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.
4. Dado head operations are much the same as those with
a standard blade. Since the dado head takes a larger
bite, the work should be held more firmly. It is a good
practice to use a hold-down jig like the one shown in
figure 70.
5. When a groove wider than the dado head is required,
make two or more passes, The best method is to use a
notched stop block to position each successive cut. (See
figure 71.) The block is fastened to edge of table where
it can be used to position work before starting the cut,
but in a position that will not permit contact with work
during the cutting operation. Space the cuts so they
overlap slightly.
6. When cutting a gain (a groove that is closed at one end)
use a stop block to fix the end of the cut. (See figure 70.1
To locate the stop, place the work alongside the dado
head in position in which it will be when cut is finished.
Then rig the stop at the end of the work. When cuffing
a stopped groove (which is closed at both ends) also use
a starting block, as shown in figure 72. This is located
in same manner as the stop block,
SANDING
A sanding wheel can be mounted on the saw arbor and the
tilting arbor of the saw" provides a high degree of versatility
for fine sanding operation. (See figure 73.)
STABmL|ZmNG WASHERS
FOR THmN BLADES
Stabilizing washers should be used only with thin blades.
When using these washers, the maximum depth of cut cannot
be obtained and the washers must be kept below the bottom
surface of the table insert.
