Planing Glued-Up Boards
WARNING

Glued-up stock must dry for 24 hours before
being planed!
Failure to comply may cause the stock to
come apart in the planer leading to kickback
which can cause serious injury!
The JWP-12DX planer is designed for planing
solid wood. Other material, including glue, will
dull or damage the knives. However, when you
need to 'true-up" glued-together stock, follow
these suggestions.
As you glue the stock, scrub off all the glue on
the surface with a wet rag. This prevents glue
beads from forming on the wood surface. Allow
the glue to dry at least 24 hours. Check the
surface for any glue that you missed and
remove with a scraper, chisel, or sander.
Set the cutterhead for a shallow depth of cut.
When you are finished planing the glued-up
board, unplug the planer and check both planer
knives for built up pitch or other signs of wear.

Adjustments

The planer comes adjusted from the factory. If
adjustment is necessary follow the steps listed.
Thickness Scale Pointer Adjustment
1. Place a board on the planer table.
2. Lower the cutterhead so that the planer
knives are just above the board.
3. Plug in and turn on the planer.
If the planer knives touched the board,
plane the board, and immediately turn off
the planer. Do not move the cutterhead.
If the planer knives did not touch the board,
very slowly lower the cutterhead until the
planer knives touch the board. Plane the
board and immediately turn off the planer.
4. Measure the thickness of the planed board.
If the scale pointer (A, Fig. 11) does not
match the thickness of the board, adjust the
pointer with a screwdriver.

procedure to check and align the cutterhead
parallel to the cutterhead:
1. Disconnect the machine from the power
source.
2. Cut a hardwood
approximately 1" thick x 5" high x 4" wide.
On one end, cut 45º bevels on all four sides.
3. Raise the cutterhead to the top.
4. If necessary, rotate the cutterhead so that
both knives are pointing away from the
table.
5. Place the gauge on the right side of the
table, as shown in Figure 11.
6. Lower the cutterhead so that the cutterhead
(not the planer knives) very lightly touches
the top of the gauge.
7. Grasp the gauge near its bottom and
carefully slide it along the table to the other
side.
