Crown 4-1/2" - 28
Crown 4-1/2" - 28
This delightful 4.500" - 28 terminating crown mould measures 4.517" in width by .750" thickness, enabling the use of four-quarter lumber for machining sprung (laying horizontally flat) on an industrial moulder. The beautiful profile contains a 5/16" vertical line connected to a 1/4" wide by 5/16" tall perpendicular notch on the top left. The right angle connects to a 2-3/16" concave semicircle in the center, merged with a 3/16" full flat line and two 5/16" tangent radiuses forming the ogee with a 3/8" horizontal fillet on the design's bottom right side. The fixed spring angles are set at
thirty-eight and
fifty-two degrees; these particular 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 3-7/16" tall with a projection of 2-15/16" 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.
