I finished up fabricating the flap pulley brackets, fit then drilled them. I broke it all apart and cleaned deburred and primed the brackets. Once dry they are ready to rivet. I also preped the main ribs for riveting by marking nonstandard riveting locations. Next session I will recheck all plum and square and start RIVETING MY WINGS TOGETHER! Main ribs are first I could not be happier to be ready for this. Merry Christmas to all.
