Crown Moulding 3-9/32" - 4

Crown Moulding 3-9/32" - 4

This beautiful cyma crown moulding 3-9/32" - 4 measures 3.289" wide by .812" thickness, enabling the pattern to be milled from four quarter lumber. The duel cyma profile is composed of a two tangent radius cyma reversa on the top, connected to a double tangent radius cyma recta in the middle, joined to a 13/32" tall by 11/32" wide squared lines at the bottom of the detail. The spring angles are fixed at thirty-eight and fifty-two degrees, these specific back bevels set the installed height at 2-9/16" tall with a projection of 2-1/16" wide.

Read 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. Three 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 moulder pressure shoe is parallel to the machine bed plates.
