Follow our step by step instructions to cut inside and outside miters for crown molding.
How to cut inside corner crown molding with miter box.
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.
This guide highlights the best practices for cutting crown moulding using miter saws how to cut crown moulding angles for corners how to cut crown moulding inside corners using a tight fitting cope joint and also the option of using crown moulding corner blocks.
Corner joints in crown molding are compound because each cut end has two angles a miter angle and a bevel angle.
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.
After that make your cut in the same manner you did before.
The advantage to cutting crown molding using this method is that no bevel cut is required.
