Before beginning the real wiring, I first have to install all that goes behind the panel.
So I first gathered all that is needed. On the bottom row, the four fuses blocks.
On the top row, the angle of attack CPU, the safety trim CPU, the flaps positionning CPU, the alticoder, the pressure switch for the trim CPU and a diode.
To make sure I had forgottent nothing, I decided to mark all the items included in the wiring (some 130 parts).



I then installed the static and pitot fittings to the EFISes and autopilot. I also fitted the connectors to visualise the space left to install all the stuff. That is the next task.

I first fabricated the support angles for the rear of the radio trays. After some iterations this is the result on the left side (the right side looks the same).



I then installed all the instruments in the panel. The holes and grommets for the park brake and heating cable where done in the subpanel.
I had some problems with the fresh air vent brackets. The nuplates were not perfectly aligned. After some small filing, the left side looks good, but ont the right side I will have to replace one of the nutplates. This will be done next time the panel comes off.
This test install allowed me to see that I'm missing some screws. I will also be able to plan the wires routing, the static and pitot pressure routing. I will also be able to plan the installation of the fuse blocks, the alticoder, the flaps, trim and AOA CPUs.

I have received the panel support rib and did all the work to install it: drilling, deburring, dimpling. I still have to prime and to paint it.



I then put some finishing touches on the panel: riveted one missing nutplate and drilled the holes for the tab washer of the switches.
I also riveted the nutplates on the mapbox.



I installed the panel and subpanel into the fuselage as I have to fabricate the rear support bracket for the radio trays.
I have not decided how this will be done and first will have to adjust the trays to the subpanel.

Before riveting all the aluminium angles to the back of the panel, I spray a light coat of primer where the parts will mate.
I then rivet all the angles and the nutplates.



I then make a trial installation of the switches. I will have to buy a feaw more as they are not all the same.



The switches get installed with some wahers. One of the washer has a little tab. So I drill the back of the panel being careful not to drilled through to avoid having a hole below the switch.
The (bad) picture shows the result.

Work goes on on the panel. I drill all the nuplates holes, drill all the holes to final size and countersink where needed (almost 100 holes).
I then install the round instruments, despite having made a template to drill the srew holes I have to ovalize some to get a nice fit.
The picture shows also that I needed to use metric screws for the instruments on the right, and "inch" screw for the one on left.



Then I sand all the edges and deburr all the holes.
