How to Cut Crown Moulding for an Outside Corner
Crown moulding is a type of decorative trim used to transition a room's walls to its ceiling and can often add a sophisticated aesthetic at minimal cost and effort. While a traditional room layout may only be a basic rectangular shape with only four walls and inside corners, it is not uncommon for a room to have several walls resulting in outside corners. Cutting crown moulding for outside corners is no more of a difficult task than that of an inside corner, and can be completed with basic knowledge of finish carpentry. Does this Spark an idea?

1
Measure and mark the cut length (length of the wall) necessary for the pieces of crown molding using the tape measure and lumber pencil. Make the mark on the bottom edge of the crown moulding.
-
2
Set the cut angle on the circular chop saw. This angle is half of the actual corner angle, as the two cuts will add up to the whole angle amount. Most chop saws can be adjusted by way of a lockable knob on the front of the saw. Refer to the saw owner's manual for operation and safety instructions.

3
Lay a crown moulding piece on the chop saw cutting surface, with the mark made in Step 1 facing up and against the back rail of the cutting surface.
-
4
Line up the saw blade with the mark made in Step 1.
-
5
Grip the crown moulding while pressing it against the saw cutting surface firmly, and engage the saw motor (the trigger is on the handle). Gently lower the running saw blade into the crown moulding; avoid forcing the blade through the wood. Retract the blade when the cut is finished, and disengage the saw motor.
-
6
Move the chop saw blade to the opposite angle (as done in Step 2) and cut the adjacent piece of crown moulding as done in Steps 3 through 5.
-
7
Check the cut angles and lengths against the walls where the moldings are to be applied and correct as necessary.
