Empennage, Rudder (Part 10)

I dimpled all the holes in the Left and Right Skins yesterday.  Today, I dimpled the corresponding holes in the flanges of the R-00915 Stiffeners, R-00902-1 Spar, R-903, R-912, and R-00915-1 Ribs, R-00918 Attach Strips, and R-00910 Horn Brace.  I was able to use the DRDT-2 to dimple the holes in the Stiffners, but due to clearance issues, I had to use the Pneumatic Squeezer for all the other parts.  

The last piece I need to prepare before final assembly is the R-916-1 Trailing Edge Wedge.  Tomorrow, I will machine countersink both sides of the Wedge to accept the 3/32 dimples in the Skins.  

Here I am dimpling the Stiffeners, Spar, Ribs, Attach Strips and Horn Brace.
