This is how you determine the spring angle using a prosite protactor. The Red scale shows the angle for a miter cut and the Black scale shows the angle. These are set up to match your MITER SAW ANGLES. This is crown in position sitting at it's spring angle to the fence. The spring angle for this crown is 45/45 That isn't always the case. 45/45 and 52/38 are the most common but you will find others. 45/45.
Find the angle based on the cosine. You can use the arccos or cos-1 function on your calculator to find the angle Î¸ from a known cosÎ¸ value. For some results, you may be able to work out the angle based on the unit circle.1  In our example, cosÎ¸ = â2 / 2. Enter arccos(â2 / 2) in your calculator to get the angle..
