Brief Description: Gretz Mount: Drill Angle; Dimple; Prime
Once the angle was positioned and clamped to the rib, the skin and mounting plate were removed in order to drill the angle to the web of the rib. This would have been a lot easier without the top skin riveted on. Once the angle was drilled, all of the Gretz mounting hardware was deburred, dimpled, the edges polished, and then everything was primed. While I was waiting for the primer to dry, I deburred and dimpled the bottom skin for the Gretz mounting bracket.
