Little bit of time here and there this week. Pretty much running or wire at a time and making some minor tweaks in routing and LRU locations. The big change today was rerouting all the tunnel wires down the left side instead straight down into the tunnel. With that rerouting also went ahead and installed the terminal strips and adel clamps for the stick wiring on top of the gear mounts. Should work out well. Went back to work on the radios stack support angles for the third time. Got everything clamped in place and marked. Measuring three or four times trying to get these holes all in the right place. Also talked to Stein this week and they suggested switch to the Aithre CO detector. Actually much easier to wire except I had already wired for the GD-40. New detector doesn't have a status light. I was already on the fence about annunciation lights and Stein confirmed that nobody is really doing those anymore. So go rid of all the annunciators. Almost all the wires are run. I need to buy just a little bit more wire to finish up. 4/7: finally got the radio stack redrilled to a state that I'm happy with. Also added lower braces between the panel and subpanel. There is an opportunity to add some support plates to grab the back GTN screw holes. I'm not sure if they're needed but it will stiffen everything up nicely. Just a note that the upper most mounting holes of the GTN use #8 screws. The previous owner of this rack may have drilled those out larger. It seems Garmin oversized the holes, but those top ones just felt like #6s were barely holding. 4/10: made brackets to support the rear of the GTN. Not sure if it is needed, but it was convenient enough and really stiffens it up.
