Turned over the flat table to to the fresh side. Began to assembledleft and right flaps per Vans plans. Drilled holes in the table to accept the bottom skin clecoes with the .75" masonry bit! Not pretty, but nothing fancier was required. By end of day, the bottom skins were drilled to the ribs and clecoed in place. Nose skins on the left flap were just clecoed to bottom when it was time to quit.
