Crown 3-1/4" - 11

This standard 3-1/4" - 11 crown mould measures 3.250" wide by .656" thickness, allowing the detail to be machined from four-quarter lumber. The terminating colonial design is one of the most common crown profiles in the moulding industry. The profile is composed of a 9/16" tall vertical line at the top, connected to an elegant two-tangent radius cyma recta in the center, joined to a 1/4" vertical fillet with a 17/32" cove and a 7/32" horizontal segment at the bottom of the pattern. The spring angles are fixed at forty-five degrees, these dedicated back bevels set the installed height at 2-15/32" tall with a projection of 2-1/8" 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 adequately 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.
