Grizzly G1021 instruction manual Gauge Block, Table Adjustment, To Check Table Parallelism

Gauge Block

Before attempting any table adjustments, you will need to construct a gauge block. See Figure 11. A larger gauge block diagram is also included at the end of the manual for your convenience. Precision adjustments later on require accuracy when milling the gauge block. Do not use com- mon 2x4 material. Use maple or similar type of hardwood. Do not use the planer during the milling process since the gauge block is needed first to check and make planer adjustments.

Using a magnetic dial indicator is a good alterna- tive to constructing a gauge block. Use the dial indicator whenever the instructions call for use of the gauge block and/or feeler gauge. Refer to the current Grizzly catalog for dial indicators.

Figure 11. Guide block specifications.

WARNING

DO NOT make adjustments while the planer is running. Ensure that the switch is off, power is disconnected and moving parts have stopped before making adjustments. Failure to comply could result in serious injury or electrical shock hazard.

Table Adjustment

To plane stock perfectly square, it is important that the table is parallel to the cutterhead.

TO CHECK TABLE PARALLELISM:

1.Place the gauge block on the table under one end of the cutterhead.

2.Turn the handwheel to raise the table until the block barely touches the cutterhead body. The block should not be touching the knives. See Figure 12.

3.Slide the block toward the opposite side of the cutterhead. Use a feeler gauge to mea- sure the width of the gap, if any, between the top of the block and the bottom of the cutter- head. If there is a gap, make a note, reading the distance from the feeler gauge.

4.If the block wedges tightly between the table and cutterhead when shifting from one side to the other, repeat steps 1 through 3 above, but start from the opposite end of the cutterhead.

Figure 12. Guide block indicates parallelism.

If the gap difference from one side to the other is equal to or less than 0.004", no further adjust- ment is necessary.
