Largely a repeat of the Lt side with less learning and more doing. Setup the inside angle bracket with a doubler, and re-iteratively aligned, marked, drilled, de-burred, re-aligned, and repeat.
Then hole cut the fuselage skin at 1 1/8" then Unibit enlarged the inside layer to slightly less than 1" for the fuel line 3/8" rubber grommet. Deburring and cleaning as needed. Measuring three times to avoid a big hole in the wrong place on the fuselage.
NOTE: the castle nuts are temporary to quickly hold things in place. The bottom hole is outside the 'wing profile' and needs to be countersunk.
