So I was finally able to add my bezel/plexi over the TV, and it turned out ok.
I had to cut a chunk out of the top for the aimtrak. This is because I wasn't thinking and spray painted the entire outside bezel without thinking of leaving a non-spraypainted portion for the aimtrak. After the fact, I tried removing the spraypaint with a sharp knife with no luck, so I just cut it out. Not a big deal, just another little mistake I made.
The plexi I ordered was 1" too small for my opening, but it was the widest peice they offered in the grey plexi.
You can see the opening at the bottom of the screen. This is another annoyance, but I'll live with it. I might just cut a 1" strip of plexi to piece down there
And the last thing is I drilled the plexi to the furring strips, but now the screw heads just glare at me. They are dark, but a little off color of the plexi. Also, the screw heads are not flush with the plexi.
In this picture you can easily see the hole in the bottom of the plexi, the chunk cut out of the top, and the screw heads.
Maybe spraypainting the screws black, drill bigger holes for the in the plexi (to hopefully flush the heads to the plexi), and cut the 1" strip of plexi for the bottom will fix my annoyances. Or maybe I'll just re-do the entire thing?...although I don't want to have to do that.
