New right elevator skin prep, rudder trailing edge cleaning

The replacement skin & stiffeners for the right elevator arrived this week so we started prepping them all over (match drill, mark/cut stiffeners, deburr).

 Meanwhile the proseal had cured for a week so it was time to remove the aluminum angle. It was a bit nerve-wracking, especially when the first couple clecos were extremely hard to operate and the angle appeared to be glued to the skins...for a brief moment I was afraid we had just trashed the rudder.
 But not to worry! With some gentle encouragement all clecos came out and the aluminum angle peeled off. It was only stuck where the proseal had oozed up out of the dimples. Thankfully I had a couple willing helpers to clean those while I worked on the elevator stiffeners.

 The right elevator bottom stiffeners were match drilled in place and removed.
 I had 1 complete set of stiffeners from our earlier aborted attempt at assembling the right elevator - after drilling out rivets in 720-G; deburring and dimpling the other set went quickly.
Next: hopefully back-riveting the rudder and right elevator skin!!
 
Empennage: 3 hrs
