Crown Moulding 6-7/8" - 6

This large concave crown moulding 6-7/8" - 6 measures 6.875" wide by .813" thickness, allowing the detail to be milled out of four quarter lumber. The good-looking profile is composed of a 11/32" tall vertical line joined to a 23/64" wide by 29/64" tall perpendicular notch on the top left, connected to a 5-15/32" cove in the center, attached to a two tangent radius ogee with a 25/64" wide horizontal line segment on the bottom of the design. The spring angles are fixed at thirty-eight and fifty-two degrees, these particular back bevels keep the inner profile parallel to the wall and ceiling as well as set the installed height at 5-3/8" tall with a projection of 4-5/16" wide.

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. Four high points in the detail 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.
