Cutting and Installing Door Trim

With the door to the master bath installed, Ryley conceals the rough carpentry work with door casings. Three boards make up the door casing — two side casings and a top casing. The boards are miter cut at a 45-degree angle with a power miter saw, and back cut with a hand plane to ensure a tight fit. The side casing is cut to length and hung first. Ryley begins by nailing the inside and outside edges of the first side casing. Next, the top piece is given a bead of wood glue on the mitered edge and nailed in place. Finally, the last casing is nailed in place, and the door installation is complete. More information
