1. Cut 28 pieces of cedar to measure 1-1/2"x12" using a miter saw. The lay out for the piece is 6-5-6-5-6.
2. Drill two holes one on each end of the cedar board using the electric drill and the 1/4" drill bit. Using a tape measure, measure 1" from each end to locate where to drill the holes, do this for all 28 pieces. The hole should be large enough for the metal rod to go through easily.
3. Spray paint all the pieces to the color of your choice. Spray several light coats to eliminate drips and runs. Allow to dry overnight.
4. Start with one row (6-5-6-5-6) and run the metal rod through one end of the cedar board, continue this with the next row, weaving the boards back and forth to create the above lay out.
5. Secure the cedar boards at each end of the metal rod with 1/4" lock bolts and washers.
6. Using Cedar cut a frame to go around the entire outer perimeter of the mat. Drill pilot holes into the frame to allow the metal rods ends to be hidden in the frame.
7. Secure the frame using galvanized screws at each of the four corners.
