How to Build a Bar

Lay pieces of molding one by one inside the recessed panels created by the stiles and rails, and mark their length. Using a miter saw, cut the ends at a 45-degree angle, then nail each one in place with 1¼-inch nails. Hold off on the pieces alongside the corner rail for now.

Tip: For a tight fit, miter one side of a long piece of panel molding, hold it in place, and use the panel's corner to mark a precise cutline for the opposite miter.
