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).
