Completed drilling the hinge to the trim tab. Now I need to remember to polish it (both sides) before riveting. Remade the elevator root ribs. The ones I made before were too wide relative to the print, plus I didn't notice the bend angles. On these root ribs, only one side is bent to 90 deg. The other to 86, and the 3rd to 107. Again they turned out to be right on relative to the print.
