Once you have determined the property line and legal setback, mark out the location of the fence. Mark the locations of the corner post holes with spray paint. Mark the locations of the remaining line posts, keeping the distance between the posts evenly spaced at approximately 55 1/2".
Using a post hole digger, dig holes approximately 18" deep and 10" in diameter. Add a few inches of gravel to the bottom of the holes for drainage. Insert 4" x 4" posts in holes. Ensure the posts are level and plumb. Mix fast-drying cement according to manufacturer's directions and pour it into the holes. Let cure for 48 hours.
The bottom rails are 2" x 4"s with 2" x 2"s on top with holes drilled in to accept the 1/2" pieces of electrical conduit. The conduit will be sandwiched between a bottom and top rail. Attach 2" x 2"s down the center of 2" x 4"s with 2 1/2" deck screws. Measure and cut so that they fit snugly between the fence posts. Construct top rails in same fashion except do not yet screw the 2" x 2"s onto the 2" x 4"s.
Draw a line down the center of the top and bottom railing 2" x 2"s. Using a drill press and 3/4" drill bit, cut holes for conduit along the center lines. Consult local codes to determine proper spacing between pickets. Repeat the process for all rails, making sure that the holes in top and bottom rail sets line up.
