Owner Tutorials - How to install crown moulding
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.
In classical architecture this shape is known as a Cyma Recta, from the Greek words for "wave" and "upright".
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,
(it helps me keep this tutorial free ). Thank-you -Gordon-

If you already have 18v dewalt this unit comes without the batteries
With the 52/38 crown, you will place the crown as in the picture to the above.
Above is the typical framing you will be nailing to. Look for studs at 16 on center for most homes.
I use the Zircon sensor, to locate studs.
Second is to know what is difference between a bevel and miter?
Bevel is moving the blade side to side to the angle on the arm
Miter is moving the blade side to side to the angle on the table

Third what is a Spring Angle?
Starrett 505A-12 ProSite Protractor Under $40.00
Red scale shows the angle for a miter joint
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.
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
