Inner cooler functioning doors (cont)

pic 1/2:
The aluminum tape was applied to the inside parts as well as to the outside of the doors since part of the inside will show when the doors are open.
There really should be an inner wall showing when the doors open but I'm not sure I can install them without interfering with the door movement.

pic 3:
The rivets down the middle were aligned with the row of rivets on the fuse at that location.

pic 4:
Lock nuts used to hold the 6-32 pivot screws.

pic 5-9:
I had to move the servo mount from the left side to the right side in order to get the doors to open when the cowl flaps open.
I also put a 1/4" square piece of ply from next to the servo to the wider part of the tray to keep the servo from bending the tray (since the tray is only 1/16" thick ply).
Since I was moving two doors, I knew that I would need a lot of variables built into the moving mechanism to be able to adjust both control rods to two different doors thus:
The ball link on the left is connected to the inner most hole whereas the ball link on the right is connected to the third hole.
I used great planes screw-lock push rod connectors (GPMQ3871) on the servo arm.
The servo arm is an adjustable servo arm.
I cut some flat brass sheeting, put a screw-lock connector on the brass sheet and soldered it to the right push rod.
With five variables (2 control horns, 2 screw-lock connectors and an adjustable servo arm), I was able to get both doors to open at the time and same distance (after several adjustments).
I forgot that I also drilled three holes in the brass sheet for the left door this variable was not used.
I used all brass rod for the push rods since they won't be getting a lot of stress and brass is easier to solder and brass is also less likely to allow screws to vibrate loose that are in it.
(that's all probably as clear as mud!).


Here's a video of the functioning inner cooler doors (outside the fuse):
