Crown 2-5/8" - 18

This 2-5/8" - 18 concave crown mould measures 2.608" 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 well-crafted terminating profile retains an 11/32" vertical fillet on the top left. The short line connects to a 1-5/16" cavetto tangent off a 3/16" convex arc in the center with a 7/16" quarter-round on the design's bottom right corner. The spring angles are at forty-five degrees; the dedicated back bevels keep the face sides of the pattern parallel to the wall and ceiling. These specific angle positions lock in the installed height at 1-15/16" tall with a 1-3/4" 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 adequately 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.
