WM 48 Crown 4-1/4" - 18

This WM 48 crown mould 4-1/4" - 18 measures 4.250" in width by .687" in thickness. The timeless terminating profile consists of a two-tangent radius cyma recta in the center. It's flanked by a 15/32" vertical line on the top left and a 1/4" tall line below. The lower portion is attached to a 19/32" radius cove and a 7/32" wide horizontal fillet on the bottom right side. The spring angles are fixed at thirty-eight and fifty-two degrees; these particular back bevels keep the inner profile parallel to the wall and ceiling and set the installed height at 3-7/16" tall with a projection of 2-1/2" wide across the top. The recommended rough wood rip size for milling sprung (laying horizontally flat) using four-quarter lumber is 4-1/2" 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 adequately calibrated. Two 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.

The current combined high-speed steel knives & template prices are listed below for quoting purposes. On most of our crown designs, we utilize a full 2.375"/60mm cutter head for the back bevel angles to allow for multiple axial adjustments on a wide range of profiles.
