Crown Molding Angles: Crown Molding Angles By Justin Baker Justin Baker's Bio:: Justin Baker's Bio: Hi, I'm Justin Baker your host here at Moulding Installation. What can I tell you about mouldings that you don't already know? Well, a lot, I hope!! I've been in the construction business for years, mostly as a general, but now have downsized to just doing specialty projects. PowerPoint Presentation: Cutting crown molding angles is quite simple and easy. If you have ever dealt with crown moldings before, you will know that the only thing that is different from other moldings is that crown moldings are sprung from the wall. The angles at which they are sprung from the wall are called the spring angles. Most moldings are either sprung at 38 or 45 degree crown molding angles, but there are some in between too. Please visit our website, Crown Molding Angles: Please visit our website, Crown Molding Angles The inside edges of a crown molding can be cut using two different methods. You can cut 45 degree crown molding angles by placing the base of the molding alongside the bottom back edge of the saw base as well as the back plate, then adjust the bottom edge of the saw base in such a way that it cuts at 45 degree crown molding angles. You should bear in mind that the crown molding is going to be fixed on the ceiling. For that reason, the back plate on the saw works as the height of your ceiling. The second piece of crown molding will be required to be cut using opposite crown molding angles. Alternatively, the inside corners of a crown molding can also be cut by positioning the crown molding flat alongside the saw and then adjust the crown molding angles to 31.62 degrees and 33.9 degrees. Most miter saws will have these crown molding angles marked on the tool.
