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.

To begin the new year, still some old work with some more holes in the panel. First I make a template to drill the holes for the mounting screws of the round instruments, it takes much longer than expected to get it right.
Then it's only a matter of minutes to align everythins and drill the holes. They are still small diameter, final drilling will be done later.



Then I drill the holes for the angle of attack display.



And finally the holes for the intercom and the standby compass.

Still drilling holes in the panel. First the center stack with the Garmin 496 support anf the EIS 4000.



Same picture with instruments installed.



I then dril the holes for the support rib and draw the ouline of the hole for the left side EFIS. But before drilling that I decide to drill the round holes for the instruments going beow the EFIS. I first drill 3/4" holes with the step drill bit.



I the use a punch to make perfect holes in less time that it takes to describe the process.



And here the result swith the standby airspeed indicator. The hole to the right od the center hole is normally the one for the left support rib. I will fill it before final paint.



And then I drill the EFIS hole. I'm not done yet as I still have to drill for the trim indicators, the compass, the intercomm, the park brake and various lights and switches.

Today I made the big hole for the right side EFIS and for the VHF and transponder. With yesterday's experience, I could cut nearer to the final line with the jigsaw.
This is the first cut.



After filing the upper and the top of the side edges, the EFIS was slided into postion.



And a picture with everything in place after the filing of the lower edges.
