Dimpled the skin of the vertical stabilizer using a combination of my hand squeezer, vice grips dimpler and hammer dimpler on my custom table, for those holes out in the middle. After this I riveted the ribs to the front spar and cleco'd the skin around the front spar and ribs. I'm going to wait for my pneumatic squeezer to rivet the rear spar together... wish i would have for the front too. I drilled out and replaced about four rivets at the intersection of the front spar, bottom rib and bottom nose rib. These all come together at and angle and it's tough to come on it straight with either rivet gun or the bucking bar.
