I spent most of the day working on the tray for the magnetomers. They need to be at least 10" between them and at the same angle as the EFIS, which required to be about 4 degrees down.
After fabricating all the parts, bending the tray to the appropriate angle, I cleaned and primed all the parts. I then riveted the parts together.
I still need to pick up some brass screws and nuts.
I also picked up some 1/8" jacks for music inputs to the intercom. I installed one of the jacks in the rear of the armrest.
