CONSTRUCTING GAGE BLOCK
In order to check and adjust the height of the chipbreaker,
pressure bar, infeed and outfeed rollers and adjust the
cutter-head parallel to the table, you will need a gage block
made of hard wood. The gage block can be constructed
by following the dimensions shown in Fig. 36.
ADJUSTING CHIPBREAKERS
The chipbreakers (A) Fig. 37, are located on top of the
planer and extend downward around the front of the
cutterhead. The chipbreakers will rise as stock is fed
through the planer and “breaks or curls” the wood chips.
The bottom of the chipbreakers must be parallel to the
knives and set .040" below the cutting circle. To check and
adjust the chipbreakers, proceed as follows:
1. DISCONNECT MACHINE FROM
POWER SOURCE.
2. Make certain the knives are adjusted properly as
explained in section “CHECKING, REPLACING AND RE-
SETTING KNIVES.”
3. Place gage block (B) Fig. 38, on the table surface and
directly under the cutterhead as shown. Using a .040"
feeler gage (C) Fig. 38, placed on top of the gage block,
raise the table until cutterhead knife (D) touches the feeler
gage when the knife is at its lowest point.
D O N O T M O V E T H E TA B L E A N Y
FURTHER UNTIL THE ADJUSTMENT HAS BEEN
COMPLETED.
4. Move gage block (B) Fig. 39, directly under chipbreakers
(A) as shown. The bottom of chipbreakers (A) Fig. 39, should
just touch gage block (B).
5. If an adjustment to the chipbreakers is necessary,
loosen two hex nuts (E) Fig. 37, and turn adjustment
screws (F) until chipbreakers (A) Fig. 39, touch gage block
(B) at both sides of the table.
