Crown Moulding 4-1/4" - 67

Crown Moulding 4-1/4" - 67

This ovolo shaped crown moulding 4-1/4" - 67 measures 4.250" wide by 1.000" thickness, requiring at least five quarter lumber to mill this pattern on an industrial style moulder. The symmetrical semicircular profile is comprised of a 2-13/16" radius arc in the center, attached to a 1/4" wide by 1/2" tall squared lines with a 1/8" eased edge on the top, and a 1/4" tall by 1/2" wide squared horizontal line also with a 1/8" rounded edge at the bottom of the lovely design.

The spring angles are fixed at forty-five degrees, these dedicated back bevels set the installed height and projection at an identical dimension of 3" tall and wide. Read our commentary about axial constant positioning for crown bevels, the article will help you dial this profile in axially on the first try when milling this detail provided the machine is axially calibrated. You may want to consider using a felt lined pressure shoe while milling this detail, this will eliminate any unsightly burnish mark that may be caused by the metal hold down shoe.
