Crown 8-1/16" - 1

This concave 8-1/16" - 1 crown mould measures 8.046" wide by 1.250" thick, requiring the use of six quarter-lumber pieces for machining on an industrial-grade moulder. The graceful terminating profile features a 7/8" vertical line segment on the top left. The line joins to an eight-inch radius concave semicircular arc in the center with a 9/32" broad horizontal fillet and a 3/8" by 3/8" perpendicular line on the bottom right corner of the design. The fixed spring angles are set at thirty-eight and fifty-two degrees; these particular 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 6-1/2" tall with a projection of 4-3/4" across the top.

Our purple colored ceramic blend grinding wheel, hogging at 2000 rpm with a twenty-five-degree back clearance angle, will rough grind a set of high-speed steel cutters in a minimal amount of time. Review our article on the importance of having the profile grinder level. This commentary will ensure prolonged use of your machinery while maintaining consistent perfection when manufacturing the cutters.
