CONSTRUCTING
GAGE BLOCK
In order to check and adjust the height of the
chipbreaker, infeed and outfeed roll and adjust the
cutterhead parallel to the table, you will need a
homemade gage block made of hard wood. This gage
block can be constructed by following the dimensions
shown in Fig. 38.

ADJUSTING HEIGHT
OF CHIPBREAKER
The chipbreaker extends down around the front of the
cutterhead and raises as stock is fed through the planer.
The chipbreaker “breaks or curls” the chips as they
leave the cutterhead and the bottom edge of the
chipbreaker helps hold the stock flat down on the table
during the planing operation. The bottom of the
chipbreaker must be parallel to the knives and set
0.020" below the cutting circle. To check and adjust,
proceed as follows:
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Make certain the knives are adjusted properly as
explained under “CHECKING, ADJUSTING AND RE-
PLACING KNIVES.”
2. Place the gage block (A) Fig. 39, on the table directly
under the cutterhead as shown. Using a 0.020" feeler
gage (B) placed on top of the gage block, raise or lower
the head assembly until one of the knives just touches
the feeler gage when the knife is at its lowest point. Then
lock the head assembly in this position.
3. Place the gage block (A) Fig. 40, minus the feeler
gage, under one end of the chipbreaker (C), as shown.
The bottom of the chipbreaker (C) should just touch the
top of the gage block, as shown.
4. If the height of the chipbreaker must be adjusted,
remove the top cover of the machine. Loosen nut (D)
Fig. 41, and turn screw (E) until that end of the
chipbreaker is properly adjusted. Then tighten nut (D).
5. Place the gage block on the other end of the
chipbreaker and if an adjustment is necessary loosen
nut (F) Fig. 41, and turn adjusting screw (G).
