Aileron Torque Tubes Complete

Got the left and right aileron torque tube assemblies completed. I primed the interior of all the steel parts 3 days ago then finished up the riveting and fabrication today. Progress was slowed by the precision tolerances needed orientating all the parts prior to match drilling. It was a "measure 20 times, drill once" situation. For example, the overall length tolerance was 17 3/4" to 17 25/32". A 1/32" difference. The brackets are offset on the torque tube by 1 1/64" using a small wood block. Figuring out how to precisely measure everything, clamp it down and drill it was a challenge. I got it done and was pleased with the end result.
