After that, make sure you’re molding flat against the saw’s table and fence. Ensure that the bottom edge is against the fence. And the top edge should be against the table.

Use your pencil and draw a line on the painter’s tape. Draw where exactly the molding rests. That line should be where the top of your molding should end. Repeat the process with the other side.

While making an outside corner cut, start by placing the molding on the right side of the miter joint. And ensure it’s on the left side of the saw. And everything should be upside down.

Then set your saw to 45 degrees to the right. And place the molding against the guide you’ve just made. Now, you can start cutting your crown moldings. Repeat the same process on the other side.

  • Be careful while adjusting your miter and bevel angles in accordance with the molding specifications. It’s important to understand that different molding requires a different angle.

  • If you don’t know how to use the device correctly. We advise you to make cuts on scrap wood. You can use this as your practice tool.
  • Always read the user instructions before using your device.

Corner Angle

You should always pay attention to the corner angle. It’s important for you to know it to have perfect crown molding. This angle cannot be overlooked.

If this angle is not correct, the joint will not fit properly. However, it’s crucial to remember that not all corner angles are 90 degrees. It’s not like what you thought.

In this situation, a protractor may be useful. It can measure the corner angle perfectly.

Spring Angle

Simply said, this is the angle at which the crown molding protrudes from the wall and towards the ceiling.

Insert a protractor between the crown molding and the wall to acquire the appropriate dimensions. Continue doing so until the problem is resolved. The spring angle should ideally be 38 or 45 degrees.

Miter and Bevel Angles

Knowing these two angles will allow you to calculate the angles of your saw correctly. You can use a finder or a bevel angle chart to check out these two angles.

The angle finder is the simpler of the two. However, you must make certain that you follow the directions in the user manual. You have to do this in order to comprehend the essential actions to take.
