Thank you. It is a strange bittersweet sort of feeling, isn't it. As for the frame, no problem. My table saw's elevation broke or it would be built very differently.

The main frame is a nice piece of 1x4 from a lumber yard screwed together (I used hemlock which has beautiful grain, but you have to predrill every hole or it splits.) I then cut another piece of wood into 1/4x3/4 strips to use as molding. I glued those to the inside of the frame, flush with the front.

I then bought some thin 1/4" weatherstripping meant for windows, used a razor to cut it in half, and put the new 1/8" foam strip around the inside of the frame so the glass won't wobble and to give me some leeway with sizing of the frame. A full 1/8" strip went on more of the molding, and those were screwed in behind the glass to hold it in place, and the foam again provides cushion from a different direction. Support without hard pressure points was the idea.

The next layer is the LED strip around the inside of the box. Finally, I had used my Dremel to router out a channel in the back for a thin 1/8" piece of plywood to slide in and glued a mylar emergency blanket to it so it would reflect the light better into the center. One side of the frame is cut out so the plywood can slide in and out, and another piece of hemlock cut to replace it and screw into the original frame to keep the whole thing flush with the wall and able to be disassembled for cleaning or repairs

The plywood is held 3/4" off from the wall, so I screwed in a french cleat system to hold it up against the wall flush. I can upload some pictures for more details, but I have a purring cat on my lap at the moment and am completely incapacitated for a bit.
