Task: Worked on the rudder bottom fairing.

I was originally going to wait to do the rudder bottom fairing but was bored today due to thunderstorms in the area. So I decided to pull the fairing out of the box and start trimming. Van's scribes a basic trim line on the fairing, but its not complete accurate. After triming using the bandsaw and a file, I tried to flatted out the upper edge by placing 80 grit sandpaper on a piece of plywood. It seemed to work well as the edge came out straight.


Once the fairing was trimmed properly I marked a centerline 0.28" from the edge. The plans say the rivets should be approximately 2" apart. Doing that gets the last rivet too close to the edge of the reinforcement strip. So I marked 2.125" between holes (starting at the 2nd rivet in from the trailing edge). This spacing worked perfectly.


Lastly I enlarged the holes to #30 and deburred the aluminum and the inside of the fairing. All thats left is to countersink the holes.
