Adjust your blade size for moulding thickness.
Adding crown molding to the ceilings can provide an elegant, professional look. For those who have little experience with cutting trim, measuring and cutting crown molding may seem like a daunting task--but it is quite easy to understand. After a few practice cuts, trim your crown molding and attach it to the wall for a completed look.
Instructions
1. Measure the room with a measuring tape to determine how many feet of molding you need. Measure the lengths of each wall and add up the total. Add 10 percent to the amount, so you have extra to practice on.
2. Set up the miter saw on a sturdy surface. According to BobVila.com, a 10-inch blade is sufficient for cutting molding 5 inches thick or less. Thicker molding will need a larger saw blade.
3. Practice your cutting before you try to trim the actual piece of molding. Place the scrap of with the bottom edge (when hung, it will point down to the floor) facing the miter fence, which will be considered upside-down.
4. Adjust the saw for a 45-degree angle, meaning each cut you make will cut the pieces into 45-degree angles, allowing you to join them up in an inside corner for a 90-degree angle.
5. Set the saw for a left-hand cut at a 45-degree angle for a right-hand piece of molding. Once you cut through the molding, the piece on the left side of the blade is the correct piece to hang in a corner.
6. Cut the left-hand side of the molding for an inside corner by placing the molding down on the saw, with the bottom edge toward the fence. Adjust the saw for a right-hand cut at a 45-degree angle. Cut all the way through the molding, and the piece on the right side of the blade is the trim to hang in the corner to complete an inside cut.
