Is there any trick to getting the cuts right? Thanx!!
Answers:    Yes, in attendance is a trick to getting the cuts right. It simplifies the process of cutting crown immensely

1. Take a small piece of crown and hold it inside the corner of a framing square so that the flats are tight to the square.

2. Take minute of where the outside point of the top of the crown hits the square (the bottom of the crown is the snake with the cove).

3. Draw a string across your miter saw at the above number (for example, 3-3/8"). This number will vary depending on the crown you use.

4. Hold your piece of crown UPSIDE DOWN against the barricade, with the front threshold on the line. Swing your miter to 45 degree to cut the miter for a 90 degree corner. However, as another poster said, at hand are going to be few if any corners in your house that are true 90 degree. Use a bevel gauge to scribe the angle, and afterwards split it (92 degrees = 46 level miter).

5. Snap a line on the wall (BLUE chalk) where on earth the bottom will hit. You can get this number from the other side of the framing square. Set the crown to this stripe to keep it straight.

Cope your inside corners and paste and nail your outside corners. It will look great when you obtain done. Good luck.
If it is perfectly square, next it is 45 degrees. However, I own never met a wall which is perfectly square. What you have need of to do it cut some short test pieces, later put them in the spot where on earth the normal pieces will progress. If they don't fit, then adjust the angle on the saw. Hopefully, you know to cut crown molding, it have to be upside down and tilted so the part which touches the wall and the ceiling rest against the bottom and side device you are using to cut.
