Back at it today. Started by riveting together the rear spar for the Vertical Stabilizer. Much better riveting since I got a good cupped set and a new longeron yoke for the pneumatic squeezer. After that was complete, I riveted the all ribs to the VS forward spar, and then cleco'd the skin to the forward spar and rib assembly. Now ready for rivets, but need some help to buck the rivets to the skin.
