This has been a ridiculous amount of work and I’ve done parts of it more than once. Some more than twice. The margins between each electronic box to allow other things to fit is within a millimeter or two A tenth of an inch as I usually measure things is far too big.

This item is the Garmin GTR 20, a VHF radio box that plugs into the G3X. It can go anywhere really, except everywhere else is full in my little plane. Its all ready to be mounted again on the middle tray. I thought I had it previously, but I was wrong.

This being the second attempt I had to remove clickbonds and glass from the top of the center tray to have another go at it.

Those brackets at the back will go in as a new central locking device for the whole panel. Greg, the nearby sheet metal guy, took pity on me and made up a tray and brackets. This has introduced me to a whole new way of thinking. I can use lighter metal and put in bends to make them stronger. Lets ignore the fact that people have been doing this in wing ribs for 100 years. I am relatively new to the game.

A big issue is clearance at the rear of the radio box so an antenna and Sub D can fit and I need to clear the bottom of the canard and internal rib. I did fail on this a couple of times but got it right in the end. How long do you want to read this thing? Be thankful I’ve left out some of the pain.

New clickbonds at the front.

The obligatory glass and clean up.

Now you might be getting an idea of the radio mount. You can see I’m making crazy extra fittings so it all locks together.

More crazy mount madness. Hours and hours of ‘fun’.

That bent edge upright is to help hold a tray that is coming. Yes more junk is going on top of all this. The side tray is my first go at bending up a bracket. I like it.

This is the beginnings of the fit.

It all came out, was modified and went back in again several times to achieve the above, Now I have good clearances.

OK. Its in. The middle clickbond is no longer needed as I’ve changed that idea. It stays for a while just in case its useful later.

Late tonight I floxed the brackets in place. I still have to rivet them to the tray sides and glass the clickbonds after cure but you get the idea.
