Fuselage center section #79 - Forward upper fuselage part 1!

Started the upper forward fuselage today.


Started by cutting out these firewall hinges that end up mounting the cowl later.  You make two different lengths.

Then these hinge clips.  I assume these make all the geometry come out correctly.

Then the KAI's have you prep the remaining parts of the firewall by dimpling for the million #8 screws that hold this thing together.

Then they have you countersink the rivet holes that hold the #8 nutplates.  These must be flush due to the top front turtledeck cover that ends up covering them up.

Dimpling for the #8 screws.

Bending the hinge mount strip to match the firewall curves.  This is sort of critical to get it to lay nice and smooth.  Be careful not to kink the metal strip!
