Cornice, also called cornice, is a way to add character and elegance to your home. This is a decorative stucco built around the top corner of the wall, just below the ceiling, to increase the aesthetic value of the house. The cornice fills the corner joint between the ceiling and the wall.
It is usually placed at an angle of 45º and attached to the wall and ceiling. It is available in different sizes from 2 to 8 inches. The biggest problem that many people have to deal with is cutting the cornice to attach it to the wall. The ability to saw them with a cast iron saw makes it possible to saw the crowns easily and quickly, but this requires a certain amount of know-how.
Here are some tips for using a cornice saw:
Required tools
- Mitro saw. It may be a 10 or 12 inch sheet (Note : If you use a 10 inch knife, you can cut roof edges up to 4 inch high, while a 12 inch saw can cut up to 6 inch high. To form a crown that is more than 6 inches high, you need a 12-inch sliding arm or a radial saw (12-inch saw).
- Fence for sawing (note: the fence must be high enough to ensure that the crown is properly seated once installed).
- Casting support during cutting
- Carpenter’s pencil
- Tape measure
- Pushbutton Notepad Paper
With the tools mentioned above you can easily saw through the cornice with a frame saw.
Implementation of the measures
Once you have received all the tools, the next step is to take the necessary steps. It is important that you take absolutely accurate measurements. An error in the eleventh sixteenth of an inch can spoil the beauty of the work by creating visible spaces between the ceiling and the walls. You can measure it directly by placing the mould in the desired location and marking the measurement with a pencil before cutting it out.
For inside corners where the free space is shorter than the space of the mould, you can consider measuring with a tape measure, because it is not possible to place the mould directly. Measure the part and then mark the same measurement in the part. Note that the cassettes made by two different companies are not always of the same size. If you want your measurements to be consistent, then you should try to use the same tape for all your measurements in this project.
Cornhead
After measuring the casting, the next step is to cut the casting. Where the crown is placed and how it is assembled determines how the cornice is finally cut. Place the pieces upside down on the saw so that the part of the piece that comes into contact with the ceiling remains on the saw bed. You must place a section on the wall opposite the fence of your saw.
Cast iron connector
For the printing of the crown it may be necessary to make a kind of seal called a scissors seal on the wall. Piece of glue is an expression used to indicate the connection of two plasterers in the middle of the wall. Using corner cuts, you can make this connection without making it visible. Here it is not necessary to cut the shape at right angles. You need to set your saw to 22.5 degrees to cut. To ensure a precise and even corner cut, most mitre saw models are equipped with a positive stop at this point.
Turn over the roof edge of the circular saw. When cutting, it is necessary to maintain a moderate speed with a flowing movement. You don’t have to pull the blade through the tree quickly and you have to accept it because you want a cleaner saw cut. It is also important not to stop when making the saw cut, because if you stop, the tree is more likely to move, resulting in the formation of a ledge in the saw cut.
Saw the second workpiece without adjusting the dosing saw. The only change is that the material must be placed on the other side of the blade. This allows you to create perfectly customized discounts, such as the following

Cutting outside corners of crown castings
The outer corner is formed by two moulded parts that are connected to each other. Both parts should be cut at right angles to each other in the middle. A mitre saw usually has a positive stop for this angle. If you need to make a large saw cut at the other end of the mould to saw the inside corner, it is important that you do this first so that the saw cut is precisely positioned.
It is not difficult to measure cuts for outside corners. Place the moulding pen correctly and mark the lower edge with a carpenter’s pencil. You can use a straight ruler and not stick if the wall has rounded corners and a heavy texture to determine exactly where the angle is.
Place the bar upside down on the saw so that the pencil mark is aligned with the edge of the saw blade. To remove the saw blade for a smoother cut, ensure that the two flat mounting surfaces at the back of the jig are in full contact with the guide bar and the saw bed.
Place the saw in the opposite direction to cut another piece of mould that will be placed on the other side of the blade. If the angle is less than or greater than 90º, measure the angle to see the cutting angle. Set the saw at half an angle and do not cut the crown at half a right angle. For example, if you cut the outer 60 degree angle, you must cut both pieces for the crown at a 30 degree angle.
The end result should look like this:

Conclusion
When casting crowns, you have to be patient. There’s a saying: Measure twice and cut once. Accurate measurements must be taken and re-measured before cutting.
Make sure that the saw is installed correctly and that the material is properly adjusted. There is no reason to rush, because the slightest mistake can ruin all your efforts. Installing a cutting crown can be a bit complicated, especially if you have unconventional angles at home, but if you’re patient, you can get the job done.
