Today I translated the templates from yesterday into aluminium parts. This is the bracket with the rear hinge riveted.



This shows the rear hinge riveted to the subpanel.



After some drilling and sanding I had the two locks installed, but I didn't like how the brackets didn't stay closed tight. So I will install two quarter-turn locks (like the one in the middle).



This shows the locks under the panel with the locks closed.



And a view from the underside. I think I will replace the butterfly screws with some slotted screws to take the out of the way of the passenger's legs.

Not much progress today as I made a few cardboard templates for the fuse block panel. The fuses won't be reachable in flight but shoud be easy to reach on the ground.
The support will be hinged under the right side of the panel.
Before beginning, I install some parts that might cause some interference : the cigarette lighter plug, the alternate air control, a switch and the fresh air tubing shown in the picture.



I then did some test templates with the four fuses blocks and the diode.
This is not satisfactory as the lower block will interfere with the panel.



This is the final result with the support hinged to the lower part of a U channel in the back. The upper part of the U channel will be riveted to the subpanel.



This is a picture in situ, taken from the right seat. The support panel hinges down in front of the right rudder pedals.

Today I worked on positionning some parts behind the panel and fabrication the static and pitot pressure circuits.
The picture shows the back of the left EFIS, with the alticoder in palce. The red tubing id for the pitot and the white for static pressure.
I had made some nice schematics for the pressure runs but it proved unrealizable, I will draw a new schematics copying what I did in the fuselage.



This is the AOA CPU, it is bolted to two angles on the left panel rib between the firewall and the subpanel. Once set,access is not needed on a regular basis. The two small tubes pick up the pressure on the red and white circuits seen above.



This is the rear of the GPS and tight EFIS. On the meft the flaps positionning CPU and on the right the trim CPU with the speed switch.

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.
