Crown 5-1/2" - 41

This distinguished 5-1/2" - 41 crown mould measures 5.480" width by .750" thickness, necessitating the use of a 5-3/4" wide blank of four-quarter lumber for milling sprung (laying horizontally flat) on an industrial moulder. The influential terminating profile contains a 1/2" tall vertical fillet joined to a 3/8" cove in the upper left. The small concave quarter circle connects to a beautiful cyma recta derived from a 1-3/8" concave semicircle tangent to a 1-3/4" convex arc in the center. The s-shaped curvature merges with a 5/16" vertical line segment attached to another 3/8" cavetto with a 1/2" broad flat line on the design's bottom right side. The set spring angles are at forty-five degrees; these dedicated 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 3-7/8" tall with a projection of 3-7/8" across the top.
