I can't complete the horizontal stabiliser until the longeron yoke for the squeezer arrived but it is allegedly in transit somewhere over the ocean at the minute! So with every other non conflicting step complete I moved onto the vertical stabiliser.
Made scary speed of progress today with the VS ribs all fluted, edge treated 90 degreed then assembled with the connecting points with a 30 drill and then clecoed on the skin. Enough for one day and will drill to size the 40 holes in the skin tomorrow hopefully.
