OPERATION
MAKING A CROWN MOLDING SUPPORT JIG
See Figure 46.
A crown molding support jig will need to be made when
cutting crown molding with no required bevel setting. The
support jig holds the crown molding in place during the
cutting operation. When using this method, the saw can
be quickly adjusted for corners that are not 90
° square.
NOTE: A separate support jig must be made for different
widths.
To make a support jig:
 Using a piece of wood 1/2 in. thick, 4-1/4 in. high, and
23 in. long, place the wood on the miter table against the
miter fence.
 From the back side of the saw, use a pencil to mark the
wood through the holes in the miter fences.
 Drill holes through the wood then countersink the holes
to accept flat head screws.
 Attach the wood to the fence using the flat head
screws.
 Place a piece of crown molding firmly against the miter
table and the wood. Mark the height of the molding with
a pencil.
 Remove the screws and the wood from the miter fence
then cut the wood to this width.
 Using small nails and glue, attach a piece of wood
(1/2 in. thick x 1-1/2 in. wide x 23-1/2 or 28 in. long) to
the top of the wood.
NOTE: Keep nails away from the area around the blade
cutting path.
 Securely reattach the support jig to the miter fence.
 Make a full 45° left miter cut and a 45° right miter cut
through the completed support jig.

USING A CROWN MOLDING SUPPORT JIG
 Place the crown molding upside down on the miter table
with the bottom of the molding against the wood fence.
 Use the chart on this and the previous page to select the
proper miter angle.
 Lift the miter lock lever and position the miter table to
the desired setting. Push the miter lock lever down to
securely tighten the miter table.
 Make sure the slide lock knob is tightened securely.
 Slowly lower the blade into and through the molding.
 Release the switch trigger and allow the saw blade to
stop rotating before raising the blade out of workpiece
and removing the workpiece from the miter table.
