Crown Molding angles

[MrHiep]

I'm looking for the formula used to cut crown molding. I have an idea of the angles for a 90 degree cut but that's it.
Thanks a lot in advance

The way that works best for me is to place the crown up side down in a miter saw, the top is now the bottom. Place the crown so it is positioned in the miter as if you were hanging it upside down on the wall. The ceiling angle should be flat on the miter table and the wall angle should be flat on the fence. Then cut your 45 either for an outside corner or for your cope cut. It's important to keep the angles tight to the table and fence when cuting. This method is limited to the size of you miter saw. If the crown is so large it won't rest on the table and fence then you won't be able to do this. I've cut 6" crown on a 10" saw with no problem. For a good pictorial check you local library for November 1992 issue of The Family Handyman. Good luck and happy crowing.
