Finished the ADS-B Mount. This included drilling the attachment panel's bottom holes and installing nutplates. All of the parts were surface converted. The angles were riveted to the longerons using pulled rivets. This was complicated slightly by the longerons slight outboard roll and close proximity to the skin. I needed to fashion an aluminum wedge with a hole, the size of the pulled rivet stem, drilled at a slight angle. This allowed me to pull the rivet at an angle away from the skin and at the same time have the wedge press down on the rivet as it was pulled. It was crude but effective.
drilled holes to match the mounting angles.
Had to cut notches in the panel to clear the lower longeron.
