How to Build a Decorative Driveway Marker

Adjust the blade depth on your circular saw to 1½ inches. Starting at the bottom end of the post, make a rip cut along one line, as shown, until you reach the top of the mark. Rotate the post 90 degrees and rip the adjacent line; the second cut should connect with the first. Use a handsaw to partially crosscut the waste piece where it's still connected at the top of the notch. Then use a hammer and chisel to cut out the rest of the waste.
