When I began building my airplane, I had grand visions for an integrated remote video camera system. I purchased a remote, two-channel DVR and a couple of "bullet cameras." (One camera was going to be built into the top of the vertical stabilizer, and the other would be on a flex-mount in the cockpit.) With the rise of GoPro cameras in the last couple of years, that plan has been totally rescinded. Unfortunately, I had already hard-wired the plane for the old system, including a mounting location on the right sidewall of the aft baggage compartment where the DVR would be mounted and notches in the wall for the wiring harness to pass through (Photo #1 below). There was no way to remove these without leaving unexplained, ugly holes in my baggage wall, so I ordered a new sidewall. (Note that any time you order replacement parts of this kind, they probably won't be pre-drilled, as in this case.)
After some careful measuring, I installed a pair of sidewall attachment nutplates and drilled the required mounting holes, and now my baggage sidewall will be pristine and perfect. And I have another part to hang on the Wall of Shame. ;-)
The next project will be similar and related -- but a bit more complex. More soon.
