Cove Moulding 5-1/4" - 4

This hefty cove moulding 5-1/4" - 4 measures 5.258" wide by 1.000" thickness, requiring a 5-1/2" wide blank of five-quarter lumber for milling sprung (laying horizontally flat) on an industrial moulder. The symmetrical terminating profile comprises a four-inch radius cavetto in the center. The middle attaches to a 3/4" tall vertical line on the top left and a 3/4" broad horizontal line on the pattern'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 3-23/32" tall with a 3-23/32" 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 are 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.
