Garmin box mounting underway. Yes, it’s a titanic pain in the ass, both to locate them so that each piece of the puzzle fits, and to actually reach both sides of each fastener for installation. Nevermind the two or three times most of them had to come off and go back on.
Anyway, here’s the GAD27 in and ready to fly.
The GAD29 and GEA24 have now both found their homes. Wiring cleanup and zip-tying are obviously yet to be done…
This area of the sub-panel will also mount the main buss bar, though probably from the forward side so its dangling wires don’t impinge on the magic boxes.
Here we have the transponder, its tray, and the mounting plate I’m fabricating for them. I thought about using hinges, but don’t think I’ll bother; I’m just going to drill the forward and aft edges into (respectively) the panel and sub-panel lower flanges, install nutplates, and screw it on there.
Finding a lateral location and orientation for the transponder where it isn’t hard up against the switch wiring in that area has been a major challenge. The answer is going to be mounting it with the backplate inboard. If it ever needs to come out, I’ll have to drop the whole plate, but that’s not a concern.
Here’s the remote Comm 2 box mounted on its angles. I still have to figure a way to attach the front ends to the firewall angle on which they’re resting and the aft ends to the sub-panel. I’ll probably use two short lengths of angle for the latter; the former is still a mystery.
This area of the sub-panel will also mount both the CO detector and the ground block.
