Fit the cope cut end into place against the adjacent piece then position the remainder of the piece and nail it into place.

Make a cope cut at both ends of the final piece of crown.

As you gain experience with crown, you’ll get comfortable with different cuts. Crown can follow around the perimeter of room just like the base boards. You can go around columns, into alcoves and along walls that meet at 45 degrees. Measure and mark the part of the crown that touches the wall just as you would with base boards. Bisect angles with the miter saw (e.g. 45 degree corners require 22-1/2 degree cuts).

The final piece of molding in a four-wall room will need to be coped on both ends to fit between the profiles of the two adjacent pieces.

Finish your installation by filling nail holes, caulking the joints and applying a little touch-up paint.

CMMB 1The Crown Master Mitre Box

When crown molding slips out of position on a miter saw, the misaligned cut will not properly fit the joint, resulting in extra labor and wasted materials. The Crown Master Mitre Box (CMMB) is a miter saw jig that easily adjusts to securely hold any size crown molding up to 4-1/2-in. wide. It also easily adjusts to any angle of tilt for any particular molding. The CMMB easily provides the ability to cut mitered joints from 1 to 45 degrees in crown and other other types of moldings that sit at an angular tilt. It has integrated stops on the bottom allowing you to align the saw blade exactly every time. The CMMB also requires no mechanical means of attachment to the saw you’re using, making it easy to use the same saw for other purposes, without changing any of the angles set up for your crown. Three kits are available. The Basic Kit contains one CMMB, allowing you to easily and confidently cut crown molding for most standard angles. The Pro Kit contains one CMMB as well as an Auxiliary Kit that allows you to cut angles steeper than 45 degrees—perfect for vaulted ceilings or coffered ceilings. The Pro Plus Kit contains two CMMB’s and one Auxiliary Kit. Learn more at www.crownmastermitrebox.com.SideNote
