Crown Moulding 6-1/2" - 15

This concave crown moulding 6-1/2" - 15 measures 6.500" wide by one inch thickness, requiring the use of five quarter lumber for milling on an industrial molder. The beautiful symmetrical profile is comprised of a six inch radius concave semicircle in the center, flanked by a 1/2" wide by 1/2" tall notch, and a 1/2" tall and wide line segment on the top and bottom of the design. The spring angles are fixed at forty-five degrees, these specific back bevels set the installed height and projection at an identical dimension of 4-19/32" tall and wide. We offer a deeper cove version of this pattern for your review and consideration, crown molding 6.500" - 14, this pattern will necessitate the use of six quarter lumber which will increase manufacturing cost.

Read 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. Four high points in the detail were deliberately positioned on the same plane, our disciplined design features will assure excellent hold down conditions while milling, as long as the moulder pressure shoe is parallel to the machine bed plates.

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 = 6.500" / Depth of Cut = .425" (top knives.)

Thickness = 1.000" / Depth of Cut = .688" (right blades) & .688" (left cutters.)
