One of the hardest crown molding jobs is installing crown molding on a vaulted or slanted ceiling. The installation of crown molding in these situations requires compound miter cut, which can be an overwhelming task for the beginner, and even the seasoned trim carpenter can have problems with vaulted crown installation. However, the do-it-yourself handyman can accomplish this task using a compound miter saw and knowing a few tricks.
Instructions
1. Determine the slope of the ceiling at the joint you are working on. Use a digital angle finder to determine the slope. It will give you the angle in degrees. Open the digital angle so that one arm follows the slope of the roof and the other arm follows the wall. Read the angle on the angle finder to get your slope. Check the instructions for the brand of angle finder you are using because some models require you to push a button to change between angles and degrees.
2. Set a piece of scrap crown molding on the miter saw upside down from how it attaches to the ceiling. Use miter saw stops to hold the crown molding in position for the cut. Set the saw's miter gauge to half the degrees determined in step 1. For example, if the total was 35 degrees, then set the saw to 17 1/2 degrees.
3. Cut the scrap crown molding slowly. Start the saw, and lower the blade slowly through the molding. Cutting the crown slowly helps minimize the tear in the wood fibers.
4. Check the fit of the cut using the scrap pieces of crown molding you just cut. Adjust the cut as needed on the scrap pieces until you have a perfect fit. Use these to set the miter saw to the correct angle before cutting the good pieces of crown molding.
5. Repeat steps 1 through 4 for each joint in the crown molding.
