More riveting. Tried a bent rivet set. Not sure how these really work, as it would rotate when the gun was firing, removing the advantage of it being bent to clear the spar cap. When it rotated it 'smileyd' the rivet head. So I've got another one to drill out. I took the long straight rivet set and carved down the shank some all the way around. So it will clear the spar cap and rotation doesn't matter.
