Rudder progress

Good progress on more elevator stiffeners first today, then back to the rudder.
The new bucking bars arrived so I went back to the rudder horn brace riveting.
It was quite difficult, but using the smallest bucking bar, which only weighs a half pound, I was able to drive the AN470 rivets in the R-710 rudder horn brace. The light bucking bar and the tight space makes it quite difficult.
Once that was done I went back to the top end of the rudder to dimple, countersink and attach the counterweight, looks ok, although more threads are protruding than I would expect ( as you can see in the photo) but the bolt matches the part number called out in the plans.
