How to Mitre Crown Mouldings
Crown moulding is the trim around the top of a wall. Often painted a glossy white, it can add a touch of class to a room. Since crown moulding is set at an angle, making the mitred cuts for a properly fitted corner may appear difficult but is really quite simple. Does this Spark an idea?

Measure the length. The mitred corner will have two lengths, the length along the wall and the length along the ceiling. The simplest to work with is the length along the wall since it can be measured directly. The other length will be inferred based on the angle. Mark the bottom (the side which will be flush with the wall) of the moulding with the measured length.

Cut the moulding. Set the moulding in the mitre box so the bottom is flush with the base of the box. The top of the moulding should be flush side of the box as it will be on the wall and ceiling. Align the marked location on the bottom of the board with the center line of the mitre box. Using the proper slot on the mitre box, make a 45 degree cut through the moulding.

Attach to the walls. Using finish nails or a pneumatic nailer, attach the moulding for one side of the corner to the studs in the wall and ceiling. Fit the second piece so that it is flush with the first, and attach securely.

To hide a slight imperfection in the joint use a small bead of painter's caulk. If the moulding is to be stained use wood putty instead.
Be sure the angle is extending in the proper direction before cutting.
Always read and follow all safety precautions when working with power tools.
Use caution when working on a ladder to avoid falling.
