The joints crown molding is referred as compound since the cut on every side usually has two angles. These include the bevel angle and the miter angle.

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.

This means that you can make the two cut without much of a hassle.

Another advantage of this compound saw is the fact that you can place molding on a flat table, which is crucial when dealing with wider molding.

However, when using a compound saw it is important to realize that you and tilt the saw on the left side, but you cannot tilt it on the right-hand side.

This means that if you would want to make a 90-degree angle cut, you need to turn around the molding position for you for you to make cuts on that side.

Is this all when to come to cutting a crown molding with a compound miter saw? Absolutely not. Today we are going to discuss some on how to use a compound miter saw to cut crown molding. The following are the best practices to assist you in cutting crown molding by yourself.


Method 1: The Non-compound method

This is also referred as the vertical method. One of the best things about using this technique is that it doesn’t require a bevel cut. For you to adjust the saw for out of a square corner you are only required to adjust only the miter system.

There is no need of adjusting both bevel and miter system provided the crown material is laying flat.

Steps

1. Lay the crown material in flat position making sure that the bottom (this is the decorative side) is against the fence of your compound saw

2. Ensure the top side of the molding is placed against the table

3. The angled flats that are on the back of the molding should always be resting squarely on the base and fence of the saw.

4. Use the following angles while making cuts inside the corner and outside the corner.


Inside corners

Left side

• Set the miter right exactly at 45 degrees
• Save right end of cut

Right side

• Set the miter left exactly at 45 degrees
• Save left end of cut

Outside corners

Left side

• Set the miter left exactly at 45 degrees
• Save right end of cut

Right side

• Set the miter left exactly at 45 degrees
• Save left end of cut


Method 2: Compound method

This method is also known as the flat method. When setting the miter and bevel angles for compound miter always remember that the angles available for the crown molding are very accurate, making it hard to set them exactly.

However, since the angles can shift slightly and most rooms do not have a perfectly square corners, you should start by testing all the settings on scrap molding before making the actual cut.

Here is the procedure-

1. Place the molding ensuring that the brad back surface is placed flat on the table

2. Ensure that you have flipped the cutting material around for you to cut both the ends of the outside and inside corners.

3. Follow the procedure to cut inside and outside corners.

Remember this procedure is to help you to cut an all US standard crown crowding molding. The standard measurements of this molding usually have 38- degrees and 52-degrees angles. This method also assumes that there is a 90 degrees angle between the walls.


Inside corner

Left side

• Ensure that the decorative (top) side lays on top of the fence
• Set the bevel at 33.85 degrees
• Set Miter right at 31.62 degrees.
• Save left end of the cut.

Right side

• Ensure that the molding bottom side lay against the fence.
• Set the bevel at 33.85 degrees.
• Set Miter left at 31.62 degrees.
• Save left end of cut 

Outside corner

Left side

• Ensure that the non-decorative side lies on top against the fence
• Set the bevel at 33.85 degrees
• Set Miter left at 31.62 degrees
• Save right end of the cut.

Right Side

• Ensure that the decorative (top) side lays on top of the fence
• Set the bevel at 33.85 degrees
• Set Miter at 31.62 degrees.
• Save right end of the cut. 


Last few words

There you have it. We hope now that you can cut crown molding on your own. The process is simple provided you will follow all the steps indicated in the above methods.
