Crown 6" - 31

This gorgeous 6" - 31 crown mould measures 6.010" in width by .750" thickness enabling the use of four-quarter lumber for machining sprung (laying horizontally flat) on an industrial-grade molder. The distinctive terminating profile contains a 13/32" vertical line segment joined to a 13/32" wide by 7/32" tall perpendicular notch on the top left. The center consists of a 1-5/64" radius concave semicircle tangent to a 1-11/32" convex arc forming the graceful cyma recta, attached to a 17/64" vertical fillet and a 49/64" cove with a 9/32" broad flat line on the bottom right side of the design. 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 4-5/16" tall with a projection of 4-3/16" across the top.

Review our commentary about axial constant positioning for crown bevels, the article will help you dial this profile in axially provided the machine is adequately calibrated. Three high points in the pattern layout were deliberately positioned on the same plane; our disciplined design features will assure excellent hold-down conditions while milling as long as the pressure shoe is parallel to the machine bed-plates.
