Swing the blade of the miter saw 45 degrees to the left. Place the first piece of moulding upside down on the saw with the scrap end to the right. Brace the flat top of the moulding on the base of the saw and the flat bottom of the moulding against the saw's fence. Make a cut near the end of the moulding. Herein, what is 31. Tilting and rotating a miter saw allows you to make a right-angle joint with a wide piece of crown molding. Many saws have a detent at 31. 6 degrees for making this cut. PHOTO 4: Saws with tall fences and stops are best for cutting crown molding in an upright position. Chris Marshall: Crown molding is typically cut upside down on a miter saw so the narrow edge that will rest against the wall butts against the saw fence and the top edge of the molding that will meet the ceiling rests on the saw table. Using a power miter saw is the best way to cut crown moulding angles. The saw can be adjusted to cut at any angle–set it to 45 degrees for one side of a standard 90-degree corner. The saw can be set to 45 degrees to the left or 45 degrees to the right. Medium-density fiberboard (MDF) is another popular alternative to the traditional wooden crown molding. It is installed very much the same way as real crown molding but is cheaper and more lightweight. MDF crown molding is also very customizable, as it can be stained or painted to the color you desire.

Once you determine the angles of your room, you can set up the miter saw to properly cut the molding.

The length will be the long points for the molding when cutting inside corners at a 45-degree angle.

To find out what the spring angle is, set the crown molding into the crotch of a framing square and check where the ends align. if both numbers are the same, it is 45/45 crown. If the numbers are different, such as three inches on the wall and two inches on the ceiling, it is 52/38 crown.

For a crown molding that is 5 inches in breadth, the saw blade must be 10 inches wide. For a molding width of 6 inches, use a miter saw that is 12 inches in breadth. However, if the molding width is more than 10 inches, use a compound miter saw that has a 12 inch sliding blade.

Depending on the type of mitre saw you purchase, you may be able to make up to four different kinds of cuts: mitre cuts, crosscuts, bevel cuts and compound cuts.

The wider a molding is, the more important angle cutting accuracy becomes. Crown molding with a 38 degree spring angle is so common, in fact, that many miter saws are equipped with pre-set detents or marks at the 31. 6 degree miter and 33. 9 degree bevel settings used for 90 degree corners.
