Angles for cutting crown flat

Watch on YouTube

What happens here

The video begins by introducing the concept of cutting crown molding flat on a miter saw. The presenter explains that the miter and bevel settings for such cuts are derived from trigonometric functions (sine, cosine, and tangent). He states that for a crown molding with a 38-degree spring angle, the complementary angle used in the subsequent calculations will be 52 degrees. He also mentions that a scientific calculator (like a smartphone calculator app) will be used for these calculations.

Goal: Understand the mathematical principles behind crown molding flat cut angles

Tools and materials

  • Crown Molding Sample Unbranded — To illustrate the shape and application of crown molding
  • Miter Saw Ridgid — To demonstrate the cutting angles and eventual cuts for crown molding

Where did the miter and bevel settings for cutting crown flat actually come from? Believe it or not, these three. Don't worry, you don't need to know trigonometry. You just got to know what to punch into your phone. Let's start with 38° spring angle crown, and the complementary angle that we're using for this formula is 52°. Measure your corner. Mine is 90. Divide that by two, and you get 45. For your miter, plug this into your
