After the first pass of drilling I attached these pieces.  The first picture is of the tie down bolt attach angle and its angle stiffener. The second picture is of the web extension piece I made awhile back.

      This picture shows the rear of the spar. You can see the web extension piece mounts on the other side and leaves a gap between it and the main web. The gap will be filled when the ribs are attached.  This picture also shows the tie down angle.
