Just working on elevator counter weights and looked at a builder's website with good (actually excellent) photos for some insight. Viewing one of an elevator spar reinforcement plates and the parts were riveted together. The center hole for rod end middle of the platenut had the factory "stamped" sharp edge so was not deburred. Looked at a photo of an elevator rear spar by the control horn (riveted on), still has the raw looking cut marks as it comes from the factory on the end and edges looked sharp.
Correct me if I'm wrong and I apologize for the rant but you have to edge finish and deburr edges for these birds to last and be safe.
I'm not saying who's web page it was but just hope that this may create some awareness.
