OPERATION

MAKING A CROWN MOLDING SUPPORT JIG

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, 5 in. wide, and 23-1/2 in. long, place the wood on the miter table against the miter fence.

NOTE: Use a piece of wood 28 in. long if using the exten- sion table.

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 below to select the proper miter angle.

Loosen the miter lock handle and position the miter table to the desired setting. Securely tighten the miter lock handle.

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 the workpiece. Wait until the electric brake stops blade from turning before removing the workpiece from the miter table.

	3.	Save right end of cut

CUTTING WARPED MATERIAL

See Figures 34 - 35.

When cutting warped material, always make sure it is posi- tioned on the miter table with the convex side against the fence as shown in figure 34.

If the warped material is positioned the wrong way as shown in figure 35, it will pinch the blade near the completion of the cut.
