Crown Moulding 4-7/16" - 7

Crown Moulding 4-7/16" - 7

This concave crown moulding 4-7/16" - 7 measures 4.420" wide by .812" thickness. The cove shaped profile is comprised of a two tangent radius arc in the center, attached to a 23/64" radius cove in the upper portion with a small bevel and 9/16" tall vertical line on top, the lower portion consists of a smaller cove with a 5/16" wide horizontal line at the bottom of the design. The spring angles are fixed at forty-five degrees, these specific back bevels set the installed height at 3-1/4" tall with a projection of 3" wide. Three high points in the detail were deliberately positioned on the same plane, this specialized design feature will assure excellent hold down conditions while milling this detail, providing the pressure shoe is parallel to the machine's bed plates.

Ever wonder why some mouldings look and feel better than others in the industry? Please read our article on knife marks, learn how machine feed rates and rpm of the cutter head can directly affect the quality of your finished mouldings.

For knife quoting purposes use the calculator below, we have added only the important measurements, just determine the cutters you need. 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 moulder to help operators save time and increase accuracy during machine setup.

Width = 4.437" / Depth of Cut = .486" (top knives).

Thickness = .812" / Depth of Cut = .428" (right blades) & .605" (left knives), only one template is needed for making the side cutters.
