Tonight I spent 2 hours and I cleaned, primed and began riveting the vertical stab.
Here’s the rear spar flush rivets set. I was able to reach all of these with a squeezer, the ones holding the bottom rudder hinge bracket were a little tricky, but I managed to set them with no issues.
I also began riveting the front spar assembly to the ribs, but it was too late to get out the rivet gun for the lower ribs. The angle on the nose rib flange is too tight to get the squeezer in and I didn’t want to bend it. I’ll have to do the rest of that in the morning.
