To cut the left and right inside corners adjust the molding upright and rotate the saw so that the miter angle is set at 31 6 degrees and the bevel angle is set at 33 9 degrees.
How to cut inside corner crown molding with a compound miter saw.
One of the advantages of using a compound miter saw is that you can tilt it to make a bevel angel while rotating the saw will enable you to make a miter cut.
Non compound method vertically nested the advantage to cutting crown molding using this method is that no bevel cut is required.
