Corner molding fills the gap between the edges of the window and the wall. It comes in many styles. Follow these steps to cut corner molding in whichever design you choose.
Step One - Measuring
Successful cuts come from accurate measurements. When cutting corner molding, you will lose a specific portion of the wood due to the thickness of the saw blade—this is referred to as the 'kerf' and should be included in your initial measurements. A typical kerf measurement is 1/16 of an inch, but you should measure the thickness of your own saw blade to make sure you have the right numbers.
Step Two - Preparing Your Miter Saw
Before you cutting the corner molding, ensure that both the saw and the saw fence are functioning properly. Visually inspect the angle guide on the saw fence, and make sure the blade rises up and down without obstruction or drag.
For this project, fit your miter saw with a high quality carbide-tipped blade. If you are using a hand saw, be sure to sharpen the blade just before use.
Step Three - Making the Cuts
For corner molding, you will need to make cuts that are at 45-degree angles.
Place the corner molding firmly and securely against the saw fence and carefully adjust. Proceed to cut your angle as quickly as possible. While it may feel like you have more control over slow cuts, they can actually lead to unevenness that will look sloppy.
