I've started the final assembly of the elevators and am looking forward in the plans to see how things need to be done. When it comes time to rivet the rear spar to the skin I see that the R bottom is done first but on the L side the L top is done first. That means that the more precarious riveting with the custom bucking bar is done on the L bottom and the R top.
I'm used to doing things in the same fashion on one side as the other and am wondering what the difference is here? Is there a reason why it has to be done this way?
