The joints found on a crown molding are labeled compound because the cuts on every side have two angles.
Crown molding inside corner cuts with a compound miter saw.
Using a power miter saw is the best way to cut crown moulding angles.
The saw can be adjusted to cut at any angle set it to 45 degrees for one side of a standard 90 degree corner.
Set miter angle to half wall angle.
These include the bevel angle and the miter angle.
Rest bottom of molding against the fence and top of molding against table.
Therefore when adjusting the saw for out of square corners the user needs to only adjust the miter system as opposed to both miter and bevel systems when laying crown materials flat.
These angles are the miter angle and bevel angle you can see the biggest benefit of compound saw in this way that the blade of the saw can be tilted to cut the bevel angle and it can be easily rotated to cut the miter too.
How to cut crown molding.
It s a best practice to cut crown moulding upside down on the miter saw.

45 miter for 90 walls.
If you have a sliding two piece fence you might want to slide one side of it out of the way.
Non compound method vertically nested the advantage to cutting crown molding using this method is that no bevel cut is required.
If using a compound miter saw set bevel angle to 0 no bevel on an inside corner the top of the molding will be shorter.
After your first corner is done flip the crown molding end to end to readjust your miter position.
Compound saws are advantageous because the saw tilts to cut the bevel and rotates to the left or right to cut the miter making both angles with a single cut.
The joints crown molding is referred as compound since the cut on every side usually has two angles.
