Crown 6" - 42

This elegantly bold crown molding 6" - 42 measure 5.987" width by 1.312" thickness, enabling the use of a 6-1/4" wide blank of six-quarter lumber for milling sprung (laying horizontally flat) on an industrial molder. The distinguished profile contains a 1/2" tall by 1/2" wide perpendicular lines on the upper left. The squared lines connect to a two tangent radius cyma reversa and a 5/16" broad flat line with a 4-27/64" concave semicircle in the center. The remaining portion of the pattern consists of another 5/16" wide horizontal line with an additional free-flowing cyma reversa and a 21/32" broad line segment 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 4-3/8" tall with a projection of 4-1/8" 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 = 6.000" / Depth of Cut = .979" (top knives).

Thickness = 1.312" / Depth of Cut = .793" (right blades) & .586" (left cutters).
