Not that it means much, but I approve. I would always opt for wood, but as I say this is good enough and I like the fact you’ve managed to use the odd shape of the TV.
I wouldn’t recommend painting metal black unless you have the tools and what it takes to make it neat. Metal hand painted black always looks like from scrap yard.
These are easy enough to spray paint. I even have the necessary etch primer for aluminum here. Painted black, it will be unnoticeable among the black cd player. All of these things I had on hand.
The square tubing/paint, I had left over from my gate (it was recycled material too!) project. The gate, from start to finish took about 6 hrs. Most of which was drilling and screwing all of the pickets to the frame. Even sprayed with oil base Rustoleum, the gate looks as good as the nicest commercial manufactured part. Better, actually, since the welds are likely better than that from a production facility.
I like wood too, but more often than not, the welding is a nice option to have! The things that manage to get built just here at home, like the fence/gate, end up saving hundreds of dollars at a time. The gate that used to be there was entirely of wood and was so heavy, it ended up wearing out the barn gate hinges it was hung on until it fell off. This one will last longer than I will.
I should also mention that this plays 'against' the ever mentioned and dreaded, "WAF." My way of thumbing my nose at such a notion.
