INSTALLING THE PATTERN KNIVES
Refer to Figures 18 and 28, pages 10 and 18.
The steel pattern knives, Sears Model Numbers 23331
through 23341, are 1A"thick, and are supplied with gibs.
Use only gibs supplied with pattern knives for mounting
on the cutterhead.
To install pattern knives, all gibs (Key Nos. 40 and 42),
planing blades (Key No. 44), spacers (Key No. 43) and
cutter bits, must be removed.
• Loosen all six set screws (Key No. 41) in one cutter-
head slot.
• Use the brass punch to tap all the gibs down into the
cutterhead slot.
• Remove all gibs, spacers and cutter bits.
• Repeat the same procedure with the other cutter-
head slots.
• Be sure all slots are clean and free of any dirt,
grease, chips or burrs.
• Position the first pattern knife to be mounted in the
cutterhead slot with the proper gib.
• Slide the pattern knife against edge of the bit setting
gauge and tighten the knife/gib combination in the
cutterhead.
• Loosen three socket head bolts (Key No. 17) and
position chip breaker (Key No. 19) (see "Position The
Chip breaker", page 8).
• Rotate the cutterhead by hand and mount the two
remaining pattern knives.

• Use the bit setting gauge to align knives.
• Be sure all knives and gibs are aligned, tight and
secure.
The planer/molder cutterhead will accept multiple pat-
tern knife set-ups at one time. For example, a pattern
knife and its relief knives can be mounted at the same
time so that the relief and the molding can be done with
one gib set-up. To mount pattern knife, the gib supplied
with the pattern knife must be used. To mount back
relief knife, the bit gib and 1" spacers (Key Nos. 42 and
43) must be used.
• Install the first pattern knife in the cutterhead slot
with the proper gib and tighten the knife/gib combi-
nation. Rotate cutterhead. Use bit setting gauge and
install the two remaining pattern knives, one in each
cutterhead slot.
• Install the first back relief knife in the cutterhead slot
with the bit gib and 1" spacers. Tighten the knife/bit
gib combination. Rotate cutterhead. Use bit setting
gauge and install the two remaining back relief
knives, one in each cutterhead slot.
• The feed rollers must be lowered after the back relief
cut for molding operation. See "Feed Roller Adjust-
ment" below.
• Make sure all knives and gibs are aligned, tight and
secure.
• Turn the cutterhead by hand and make sure there is
no interference with the knife path.
To install more than one pattern knife in each cutter-
head slot, for example, crown and bed knives or tongue
and groove knives, an additional set of three gibs is
required.
Make sure the chip breaker position does not interfere
with any pattern knives. Be sure to replace the blade
cover (Key No. 8) properly after removing the bit setting
gauge. Replace the chip deflector (Key No. 15).
ADJUSTMENT BLOCK
Refer to Figure 19.
Some of the maintenance adjustments require the use
of handmade adjustment blocks (See Figure 19).
