Crown 3-1/4" - 31

This southwestern 3-1/4" - 31 crown mould measures 3.270" width by .750" thickness, enabling the use of four-quarter lumber for milling sprung (laying horizontally flat) on an industrial-grade molder. The symmetrical terminating profile contains a 1-5/32" wide forty-five degree angled line in the center. The middle angle is flanked by two sets of 3/8" wide by 3/8" tall perpendicular steps on both the top left and bottom right side of the design. The set spring angles are at forty-five degrees; these dedicated back bevels keep the face side of the profile parallel to the wall and ceiling when installed; they also lock in the positioned height at 2-5/16" tall with a projection of 2-5/16" across the top.

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 pattern layout 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.
