Crown Moulding 5-3/4" - 12

Crown Moulding 5-3/4" - 12

This beautiful symmetrical crown moulding 5-3/4" - 12 measures 5.750" wide by 1.250" thickness, this detail will require six quarter lumber for milling on a industrial molder. The concave profile is composed of a 2-31/32" radius bowl shaped arc in the center, flanked by a 7/64" tall and wide line segment with a 1/16" eased edge that transitions into two tangent 3/8" radius semicircles creating the ogee, attached to a 17/32" tall vertical line at the top and the same width horizontal line at the bottom of the pattern. The spring angles are fixed at forty-five and one half degrees to help minimize cupping after the milling process, these specific back bevels set the installed height at 4-1/16" tall with a projection of 4-1/16" wide.

Read our commentary about axial constant positioning for crown bevels, the article will help you dial this profile in axially on the first try when milling this detail provided the machine is axially calibrated. Two high points in the detail were deliberately positioned on the same plane, our specialized design features will assure excellent hold down conditions while milling, providing the moulder pressure shoe is parallel to the machine bed plates.

For knife quoting purposes click to open the calculator below, we have added only the important measurements, just enter the appropriate dimension in the boxes provided. A brief detailed explanation on how to use the calculator is located here. Need some assistance with the dimensions? Print a copy of our fraction - decimal - millimeter chart, place it on the molder to help operators save time and increase accuracy during machine setup.

Width = 5.750" / Depth of Cut = .813" (top knives.)

Thickness = 1.250" / Depth of Cut = .902" (right blades) & .902" (left cutters.)
