Brief Description: Fabricate 2 Access Panel Support Rings
My next step was to fabricate 2 support rings from 0.040 aluminum sheet that will get riveted to the bottom or inside of the top forward skin.
If I remember the dimensions correctly there is a 3/4" underlay of the top skin and a 1/2" lip that the covers will eventually be screwed down into making a flush surface.
