Crown Moulding 8" - 11

This engaging crown moulding 8" - 11 measures 8.000" wide by .812" thickness, enabling the pattern to be milled sprung (laying horizontally flat) out of four quarter lumber. The visually appealing terminating profile is composed of a 9/16" tall vertical line connected to a 1-1/16" concave semicircle on the top left, attached to a 15/32" wide by 15/32" tall perpendicular notch joined to a free-flowing two tangent radius cyma recta in the center, merged to a 11/32" vertical fillet and a 1-9/32" cove with a 25/64" horizontal line segment on the bottom right side of the design. The spring angles are fixed at forty-five degrees, these explicit back bevels keep the inner portion of the profile parallel to the wall and ceiling when installed, in addition to setting the positioned height at 5-3/4" tall with a projection of 5-9/16" wide.

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. Five 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 moulding knife quoting purposes click to open the calculator below, we supplied 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. If you would like some assistance with the dimensions feel free to 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 = 8.000" / Depth of Cut = .487" (top knives).

Thickness = .813" / Depth of Cut = .419" (right blades) & .549" (left cutters).
