I got all primed parts back and started to rivet the rear spar together. The aileron brackets were also riveted together. Unfortunately I riveted the brackets to the rear spar and too late I realized, that I need to rivet the skins first and them rivet the brackets to the spar. There would be no place for the bucking bar or squeezer. So I had to drill out the rivets of the brackets to remove them again.
