Cut two 4x4's to 87" in length.
-
Mark the first side with the square, then use that line to transfer the mark to the other sides.
-
-
-
Mark 1/2" from the end of each 4x4.
-
Transfer the line to two of the other sides in a similar manner to step 1.
-
Set your circular saw blade to a 45 degree angle as seen in photo 2.
-
Bevel 3 of the sides by using the angled blade to cut along the line. The result will look like photo 3.
-
The fourth side does not get beveled because it lays flush against the wall.
