Today I set a few rivets in the rudder. Much better success today. I did have to use the rivet gun and bucking bar for the first time. The first two went pretty well, but the third I was paying too much attention to the bucking bar and not enough to the machine head end... There's a lesson here I think :) Anyways, I drilled that guy out and squeezed it instead. I suppose everybody is telling the truth when they say shooting/bucking is a two person job, as it's tough to watch both ends closely and keep everything correct... Here's a pi9c of the rudder spar with its bits and pieces riveted together.
