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. Most saws cut from 90 to 45 degrees in both directions, and some saws can cut up to 55-degree angles. The side slopes are measured from horizontal and can be used to calculate any cuts needed at the base and top of the frustum. You need to set the blade angle and also the miter gauge angle to get the correct “hopper” angle. The height is the distance from the center of the base to the apex. Compound Miter Saw Calculator.
