How to install crown molding basics
Installing crown molding (or moulding) can seem daunting for beginners, so I'm going to try and simplify it as much as possible. Craftsmen will find this easy, but it's hard to remember the math, so I'm going to give both of you information hopefully you'll find interesting.

This is called a dentil and usually the decorative element of the trim is placed on the bottom.
This is a fairly common element in crown molding it's shape is called an "ogee" Most of the time this will be at the ceiling.

First is to know which side of the crown goes up?
Please use the crown forum, not my business email thank-you.
If you shop online please pick up something at amazon while you are here,

The Bosch Digital protractor / angle finder
I use this when I'm going to cut on flat. See flat page
With the 52/38 crown, you will place the crown as in the picture to the above.
The short run to the ceiling and the long rise to the wall. You will have more crown on the wall plane rather than the ceiling plane.

Above is the typical framing you will be nailing to. Look for studs at 16 on center for most homes.
See the setting up page for more

I use the Zircon sensor, to locate studs.
More on the setting up page.
Second is to know what is difference between a bevel and miter?
larger images
Bevel is moving the blade side to side to the angle on the arm
(Bevel: tilt of blade)
Miter is moving the blade side to side to the angle on the table
(Miter: angle on table)

Third what is a Spring Angle?
Starrett 505A-12 ProSite Protractor Under $40.00
If you get a tool to cut crown (in position)
this is it !
Red scale shows the angle for a miter joint
Black scale shows the setting for fitting a single piece to an angle.
I use this protractor, the tool is excellent quality and made of metal careful buying the plastic ones just download our paper one instead.
Use it for cutting crown in position, finding angles.
Amazon link
Position the crown in a square like this and move it back and forth until the top and bottom flanges are as close as possible to meeting flush most are beveled an additional 2 degrees.

The spring angle for this crown is 45/45 That isn't always the case, the pre-settings on most miter saws are set up for 52/38
One way to get that angle is to use your sliding T bevel and match it to a protractor.
If you don't have a protractor print out one of these. The pdf is the best choice of the two.
Without the prosite protractor you'll have to convert the angle to the miter saw angles.

A protractor to find the angles, click on image for full size then right click and print or down load the PDF & print out (better)
The most common spring angles in the U.S. are 45/45 and 52/38
