Crown 3-5/8" - 20

This ornate 3-5/8" - 20 crown mould measures 3.640" width by .750" thickness, requiring a 3-7/8" blank of four-quarter lumber for milling sprung (laying horizontally flat) on an industrial moulder. The elaborate terminating profile comprises two sets of perpendicular steps in the upper left. The lower connects to an 11/16" convex arc with a 3/32" tall fillet in the center. The remaining section consists of two tangent radius cyma recta and reverse separated by a 1/16" vertical line segment, joined to a 3/16" by 5/32" notch with a 9/32" wide fillet on the bottom right corner of the design. The fixed spring angles are set at thirty-eight and fifty-two degrees; these particular back bevels keep the face side of the profile parallel to the wall and ceiling when installed; they also lock in the positioned height at 2-13/16" tall with a 2-5/16" projection across the top.
