Crown Molding Cuts for Installation

Position the crown molding on the miter saw. The top edge of the crown molding should rest on the miter saw table while the bottom edge of the crown molding touches the miter saw fence. Every cut you make to the crown molding on the miter saw should be made with the molding in this position.

Make angle cuts on the crown molding. The simplest way to do this is to adjust the miter saw so it is set at a 45 degree angle. Position the crown molding on the saw and hold it firmly in place. Cut the molding at the 45 degree angle. This angle is used for outside corners. An outside corner is made from two opposite 45 degree angle cuts. This angle cut is also used as a preliminary cut before coping an inside corner.

Make the coping cuts to the crown molding. When creating an inside corner, the first side of the corner should be cut with the saw set at zero degrees. The second side of the corner is cut at a 45 degree angle and then coped out with a coping saw. To cope the crown molding, you need to find the leading edge of the 45 degree cut that highlights the profile of the molding. Mark the leading edge with a pencil. Hold the coping saw at an angle and cut away the back portion of the crown molding. The molding should then fit into the profile of the other side of the inside corner.
