Fuselage, FWD Lower Structure (Part 6)

Work completed on Sunday, August 11, 2019

Pictured below is the FF-01403 Battery Box.  I machine countersunk four holes on the left and right tabs to accept AN425AD3-3.5 rivets and the 19 holes around the aft side of the battery box to accept AN425AD4-4 and -5 rivets.  All the edges were cleaned and the Battery Box is now ready to be treated with Alumiprep, Alodine and Akzo primer.

These are the separated F-14103 Cable Brackets.  None of these holes needed to be countersunk and/or dimpled, so I just deburred the holes and cleaned the edges.  They are now ready to be treated with Alumiprep, Alodine and Akzo primer.

After being separated, these are the F01435A-L & -R Cover Panels.  All the holes were deburred, the edges cleaned and all of the #40 holes were dimpled.  These parts are also ready to be treated with Alumiprep, Alodine and Akzo primer.

Here are the Cover Plates after being sprayed with Akzo primer.....

Work Completed on Saturday, August 10, 2019

Since I’m still in a position where I need a rivet helper, I’m still looking ahead in the plans and preparing as many parts and pieces as I can.  In this work session, I prepared the F-14133-1 Cowl Attach Plates and the F-14134C Cowling Hinge Shims.  Each of the pieces were separated, edges cleaned, holes deburred, appropriate holes countersunk, and the appropriate holes dimpled.  The four pieces are now ready to be treated Alumiprep and Alodine and primed with Akzo.

This is the F-14102 Fuel Selector Valve Bracket.  It has also been prepared and ready to be treated with Alumiprep and Alodine and primed with Akzo.

Next, was to fabricate two VENT-00001D Vent Hinges from MS20257-C2 Stainless Steel Hinge raw material.  Here is an excerpt from the plans showing the appropriate dimensions.....

Once that was completed they hinges had to be match-drilled to the VENT-00001C Vent Doors as shown below.  I used my clamps to hold the pieces together.....

.....and then match-drilled the four #40 holes.

Lastly, the VENT-00001B (x2), VENT-00001A-R & -L (x2 each), VENT-00001F Vent Arms (x2), and VENT-00001C Vent Doors were cleaned, holes deburred, and clecoed together.  They are ready to be treated with Alumiprep and Alodine (minus the stainless steel Vent Doors) and primed with Akzo.
