|A precision hole left with a meat cleaver.|

This is gonna take some ciphering.....That's hillbilly for pondering.
I needed a doubler that would help to strengthen the skin around the whole.
There are 2 of these doublers that sandwich the outer skin.
This is the inner doubler after being trimmed to fit around secondary structure.
So, I marked the hole where the material needed to be removed.
The same thing had to be done with the interior wall.
I had a larger doubler that I riveted on the interior wall. This shows the fill valve installed.
After a little polishing and a little drilling and riveting, the valve finds a home in the original hole.
