📚 Understanding Compound Angles
Compound angles occur when both the miter and bevel must be cut simultaneously. This is common in crown molding and picture frames.
📐 Formulas
- Miter: tan(M) = tan(A) × sin(B)
- Bevel: sin(B) = sin(A) × cos(B)
💡 Tips
- Crown molding typically has 38° or 45° spring angle
- Cut test pieces on scrap first
- For inside corners: cope one piece
- Label your pieces as you cut
