Final drilled all the parts for correct counterweight positioning.
riveted counterbalance rib to skins.
I removed few pop rivets that didn't look good and replaced them with new one. Cause of the badly looking manufactured head was a defective pop rivet puller that was promptly thrown to the waste bin.
Inserted last rivet on root rib skin thanks to Lucio's magic homemade bucking bar. This was also done on the left skin, avoiding the use of a pop-rivet.
Rudder is finally complete, after having completely scrapped the first attempt....The old rudder is still there as a practice sandbox to test difficult tasks like drilling out rivets and similar activities i need to practice.
