Crown 2-5/8" - 17

This small tall crown moulding 2-5/8" - 17 measures 2.636" width by .750" thickness, requiring a 2-7/8" wide blank of four-quarter lumber for milling sprung (laying horizontally flat) on an industrial moulder. The crafted terminating profile retains a 1/2" vertical fillet connected to a 3/8" tall by 5/16" wide notch on the top left. The rabbet attaches to a 15/32" concave semicircle tangent off a 1/4" convex arc, creating the cyma recta in the center. The s-shaped curvature attaches to a 3/8" by 3/8" set of perpendicular lines on the design's bottom right corner. The spring angles are fixed at thirty and sixty degrees, these precise back bevels keep the face side of the profile parallel to the wall and ceiling when installed; they also lock in the height position at 2-1/4" tall with a 1-3/8" projection 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 properly calibrated. Two 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.
