This Crown/Cove Moulding 4-7/16" - 8 measures 4.437" wide by .750" thickness, with a .411" depth of cut on the right vertical moulding cutters and a .596" depth of cut on the left vertical blades, with a .470" depth of cut on the top horizontal set of moulding knives.
The artistic profile is comprised of a 2-3/4" radius cove in the center, attached to a 1/2" tall vertical fillet at the top, connected to a 3/8" and 1/4" tangent radius arcs creating a cyma reversa that is flanked by a 1/8" wide and 1/4" wide horizontal fillet on the bottom of the pattern. The spring angles are fixed at forty-five degree, search our bevels category by this degree to find a back bevel cutter appropriate for this innovative crown/cove moulding design, these specific back bevels set the installed height at 3-17/64" tall with a projection of 3" wide. Three high points in the detail were intentionally positioned on the same level plane, this specialized design feature will assure excellent hold down conditions while milling the detail on an industrial moulder providing the moulder pressure shoe is calibrated.
Please read our commentary about axial constant position for crown moulding bevels, the article will help you dial this profile in axially on the first try when milling this detail on an industrial moulder, provided the moulder is axially calibrated.
