2.0 Hours -
Not a whole lot accomplished today.
First, I final drilled the stiffeners to the right elevator skin. The skins are pre-punched and the stiffeners are also completely pre-punched except for the aft-most holes on three stiffeners. Those three holes are match drilled using the skin as a guide.
The right elevator stiffeners are final drilled to the skin.
Next, I deburred and dimpled all of the stiffeners. My Avery deburr tool and pneumatic squeezer made quick work of this task.

The skin also had to be deburred and dimpled. I started by removing strips of vinyl corresponding to the stiffener attach holes. As before, I used a soldering iron and straight edge. However, I decided this takes too much time for something that really doesn’t matter, so I sat the straight edge aside and just used the soldering iron free hand. I’m no artist…my lines are pretty ugly!

I deburred the stiffener attach holes in the right elevator skin and, not wanting to pull out the c-frame to dimple the skin, I called it a day.
Finally, I made a little trip to Lowe’s to get some wood and hinges to make a bending brake for the aft edges of the elevators. I also bought a dowel and a couple of vise grips for bending the leading edges of the rudder and elevators.
