Cutting Crown Molding Angled to the Table and Fence

The advantage of cutting crown molding in this position is that no bevel setting is required. Small changes in the miter angle can be made without affecting the bevel angle. When using this method the saw can be quickly and easily adjusted for corners that are not 90° (square).

Making a crown molding support jig:

A crown molding support jig needs to be constructed to help hold the molding in place during this cutting operation.

1.Get a straight piece of wood typically 1/2 inch thick by 23-1/2 inches long (28 inches long if using the table extension) and approximately 5 inches wide. The actual width of this piece will depend on overall width of the crown molding and what the top and bottom angles are.

2.Drill holes and temporarily mount this piece similar to building an Auxiliary Fence. However, do not cut the blade slot at this time.

3.Position a piece of crown molding that you are going to cut so the bottom part (part which is installed against the wall) is against the wood fence. Make sure the angles on the crown molding are held firmly against the wood fence and table of the miter saw. Mark the height on the fence.

Using the crown molding support jig:

1.Position the molding so the bottom (part which is installed against the wall) is against the wood fence.

2.Use the chart to select the proper miter angle. Tighten the miter lock knob.

3.Activate switch. Lower head, make the cut. Wait until the blade comes to a complete stop before allowing the head assembly to return to the “UP” position and/or removing the workpiece.

4.ALWAYS PRETEST COMPOUND SETTINGS ON SCRAP MATERIAL TO CONFIRM CORRECT ANGLE.

4.Remove the wood fence and cut to this width.

5.Use small nails and glue to attach a top piece (typically 1/2 inch thick by 1-1/2 inches wide by 23 inches long. Make sure the nails are not located below the sawblade.

6.Securely reattach the completed jig to the miter saw fence and make a full depth, 45° left and right miter cut.
