   A quick Google on "crown molding miter" or "crown modlign installation" will get you a few carloads of hits.

   The best way to cut crown is to forget the compound method and cut it upside down against the fence.  That way all you have to do is get the miter angle correct -- no bevel to be concerned with at all.

   Thanks for your suggestion. I agree that cutting it against the fence is a faster method. But occasionally we do very large crown (7"-10" or bigger) and this method is not possible. Thanks again

   Google Compound Angles by Rick Christopherson. It's an extremely clear article about how to calculate angle and bevel settings by using math... and you end up cutting the piece lying flat on the saw. It works!

   Ditto the math stuff for compound miter cuts for crown.  I've used the same forumula I got years ago out of an FHB article.  See all those other tables and charts are only good for 32/58 crown and/or maybe 45/45.  Not all crown, especially one 7" wide is going to fit that pattern.

   What I do is square up one end of the crown moulding laying it flat,  slide the molding over a little and make another cut.  I'll have a 1/4" thick cross section of crown moulding.  Take that to a piece of smooth plywood.  Use a mechanical pencil to trace the profile on the PW.  Then take a framing square with the 16th's side facing and complete the right triangle of the crown moulding.  Then I'll measure from the right angle corner to the inside points.  That's the numbers you wanna punch in the formula, NOT the outside points.

   Thanks for your suggestions. I like the formula. I prefer to figure things out using math instead of looking at a piece of paper.

   Thanks again.
