Crown Moulding 7-1/2" - 1

This gorgeous crown molding 7-1/2" - 1 measures 7.500" width by 1.250" thickness, necessitating the use of six quarter lumber for machining on an industrial molder. The extravagant terminating profile contains a 17/64" tall by 5/32" wide perpendicular lines on the top left. The straight line connects to a 45/64" radius convex semicircle joined to a 3-39/32" cavetto in the center. The lower portion retains a set of right angles and a 31/32" ovolo merged with a tiny cove flanked by a line segment and a 25/64" flat bottom on the design's right side. The set spring angles are at forty-five degrees; these dedicated 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 5-1/4" tall with a projection of 5-3/8" 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.

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 = 7.500" / Depth of Cut = .802" (top knives).

Thickness = 1.250" / Depth of Cut = 1.076" (right blades) & .988" (left cutters).
