Calibrating Headstock
Elevation Scale
Although correctly set at the factory, the scale can
be adjusted for accuracy if it becomes necessary.
Tools Needed Qty
Phillips Screwdriver #2 ...................................... 1
Scrap Piece of Stock

To calibrate scale:
1.
Plane scrap piece of stock until it is flat on
both sides and has even thickness along its
length.
Note: Turn scrap board over between each
pass to make surfaces parallel.
2.
Use calipers to measure board thickness.
3. If there is a discrepancy between board thick-
ness and reading on elevation scale, loosen
Phillips head screws shown in Figure 40,
adjust position of red line to indicate correct
thickness, then tighten screws.
The cutterhead/table parallelism has been cor-
rectly set at the factory. However, it can be re-
adjusted for accuracy if the cutterhead assembly
shifts over time.

To adjust cutterhead/table parallelism:
1.
DISCONNECT MACHINE FROM POWER!
2. Install knives/inserts (refer to Adjusting/
Replacing Knives on Page 27 for detailed
instructions).
3.
Place both pieces of stock on either side of
table, and lower headstock until cutterhead
just touches (see Figure 41).
Note: Having wood blocks at an even height
is critical to the accuracy of your overall
adjustments. For best results, square stock
with a jointer and table saw before using as a
gauge.
