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.

I first drill the aluminium angles for the radio trays and GPS support bracket. The angles got installed and retrieved a few times to get a correct fir.



For sure some problems creep up once the angles are installed. Here is one, the two holes are a bit close. The lest hole will get a rivet but the right one is for a nuplate, I think I will install a one leg nutplate.



I then cut the subpanel for the radio trays. In fact I think I will be able to install the trays without them sticking out below the subpanel. I have not fabricated the support brackets for the trays on the subpanel as it is not that square on the workbench, I will do it once it is in the fuselage.



I then finished the alarm lights support bracket by riveting the nutplates and glueing the shims.

Before drilling more holes in the panel, I install the left rib on the subpanel.



I also draw where the subanel needs to be drilled for the radio trays. The bottom edge of the ruler shows where the lower edge of the trays will be. It will stick a bit below the subpanel.



Then I do some drilling on the left side of the panel : the two trim indicators, the pake brake handle and the magneto switches. I still have to chose which cover I will use.



In the middle, the autopilot switch and the mini switch to change the autopilot GPS source.
I also mad a small cutout on the lower left side of the altimeter hole for the adjusting knob.



I then drill the U-channel the supports the switches and engine controls. I also drilled the holes to screw the U-channel to the pannel.



Then the last big holes for the alarm lights. They are normally installed as the red light but I'll try to install them as the yellow one.



To do this I fabricate a small bracket with two shims from leftover parts.



I this is the result. After some small teaking it should look perfect.
