Our first miter cut is going to be on the crown molding that will come along the tallest part of the ceiling and then run into the molding that goes down the slope of the vaulted ceiling.
Cutting crown molding for sloped ceiling.
The corner angle for joint b is 110 90 200 deg.
So in the illustration we will be mitering the right side of the crown molding.

Our example is a 20 degree sloped ceiling.
Crown molding detail for sloped ceilings.
This usually requires an angle setting of either 32 or 45 degrees.
Calculating angles and inside corner details for crown applied to sloped ceilings.
Make sure your scrap piece fits squarely into the miter saw before cutting.
Continue reading below our video of the day.
One of the most common methods for fitting crown molding to a slanted ceiling is to attach the molding to a filler piece that is in between.
The inside corner must be cut with the molding upside down in your saw the way crown is normally cut in a miter saw when it s in position but the outside corner of the transition piece must be.
Standard 45 degree cuts can be used on a sloped ceiling.
Note that crown molding is cut with the miter saw upside down using the saw s table as a guide to fit the molding to an angle equal to that needed to fit with the ceiling.
Use that to determine the exact low point of where the two pieces of crown will touch in the corner on the wall.
Therefore the angle between the wall and the ceiling is 110 degrees.
It s best to cut a standard inside corner template as you see in the video above.
Crown molding miter cuts.
When using a miter saw to cut crown molding for horizontal ceilings you must prop the crown molding against the fence as shown in fig 2.
With the miter saw set to 0 degrees make a straight cut to create the butt joint where the end of the moulding will be.
Measure the distance from corner to corner on the first wall.
This simple cut is how to cut crown moulding to be used in between crown.
Transfer the measurement to moulding.
When measuring and cutting crown molding pieces you will also need to take the measurements and angles of filler pieces into account.
