Created a custom bracket from an L-angle to mimic the right flange of the nose rib where the I/B and O/B leading edge skins join. This is to strengthen that area since I had to drill 8 style holes due to my mistake of installing the O/B skin first, then the I/B skin.
Drilled out spar using a #40, then #30 and finally #20. Deburred all skins and spar.
The upper skins are now ready to be cleco’ed and riveted.
