Crown 4-9/16" - 10

This standard 4-9/16" - 10 crown mould measures 4.562" wide by .562" thickness, allowing the detail to be milled from resawn six-quarter or solid four-quarter lumber. The traditional profile is composed of a 1/2" tall vertical fillet on top, connected to a two tangent radius cyma recta in the center, joined to a 19/64" tall line segment with a 41/64" cove and an 11/32" broad horizontal line at the bottom of the pattern. The spring angles are fixed at thirty-eight and fifty-two degrees, these specific back bevels set the installed height at 3-19/32" tall with a projection of 2-13/16" 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 adequately calibrated. Two 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. We recommend using a felt-lined pressure shoe to eliminate any unsightly burnish mark in the center of the profile that may be caused by the metal hold-down unit on the machine.
