How to Build a Decorative Driveway Marker

Set your miter saw to 12 degrees and trim off one end of each top rail. Butt the angled end of one rail into the top of the notch, and use a drill/driver and two deck screws to secure it. Attach the other end where it meets the end post. Use a handsaw, as shown, to trim off any overhanging rail. Follow the same steps to attach the rails on the perpendicular side. At the notch, they will butt into the rails you just installed.
