Various little projects

11 Jul 2006: all of us, 3 hours each. Lots of little projects tonight. This is a night when having three of us really pays. One task was to prepare the smaller elevator pushrod (the one between the bellcrank and the control sticks) for anodizing, which we had forgotten about when we did the larger pushrod (the one between the bellcrank and the elevator horn). We assembled the brake/rudder pedal assembly. We fabricated the left flap hinge, which involves drilling and countersinking to receive the dimpled holes in the lower wing skin. The hinge material is about the minimum thickness for countersinking, and it requires care not to enlarge the rivet holes when countersinking. We learned this the hard way, and will have to install one or two "oops" rivets at one end of the hinge. We had managed to do the entire empennage and everything else to this point without any "oops" rivets, so we were probably bound by fate to get careless at some point. Finally we started fabricating the modified cover plate and reinforcements for the right fuel tank sender attachment modification mentioned in the last post.
