Crown Moulding 6-3/8" - 9

This extraordinary crown molding 6-3/8" - 9, measures 6.375" wide by .812" thickness, authorizing the use of four quarter lumber for milling on an industrial-grade molder. The luxurious terminating profile contains a 15/64" vertical line segment merged with a 9/16" cavetto on the top left. This area joins a free-flowing 2-7/16" concave semicircle tangent to a 2-3/8" convex arc creating the cyma recta in the center, connected to a 5/16" tall line and another 9/16" cove with a 15/64" horizontal line at the bottom right side of the design. The fixed spring angles are at thirty-eight and fifty-two degrees; these particular back bevels keep the exposed face side of the profile parallel to the wall and ceiling when installed, as well as set the oriented height at 4-31/32" tall with a projection of 4" 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 properly 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.

For molding knife quoting purposes click to open the calculator below, we supplied only the important measurements, enter the appropriate dimension in the boxes provided. A brief detailed explanation on how to use the calculator is located here. If you would like some assistance with the dimensions print a copy of our fraction - decimal - millimeter chart, place it on the molder, or around the shop to help machine operators save time and increase accuracy during setup procedures.

Width = 6.375" / Depth of Cut = .444" (top knives).

Thickness = .812" / Depth of Cut = .534" (right blades) & .756" (left cutters).
