Because $150 or more for a factory made mount put me off, I was thusly challenged to make one.
I had some recycled red oak and milled the parts from it. It should be noted that I modeled the mount in
SketchUp before I cut anything.
The first challenge in the shop was getting the hinge knuckles to fit properly. The next challenge was in the plate that attaches to the back of the TV. There are 8 tiny threaded holes that must be matches as closely as possible, considering that this would be a metal-to-wood attachment. The little screws are only 4mm in size. I made a pattern by taping a sheet of paper to the TV and pressing with my finger to get an impression which I then made more visible with a sharp pencil. The paper pattern was then taped to the wood and the marks transferred with a sharp punch.
Later I found that making the holes line up when actually hanging the TV was not so easy as when the TV was lying on the table face down!
Another challenge was drilling for the hinge pins. .25” steel rod was selected but I didn’t have a bit long enough to penetrate the six inch hinges. Borrowing a long bit from a neighbor, but not as big as .25”, I used it as a pilot hole and then drilled from both ends with the shorter .25” drill bit.
The close up of the wall plate shows how I fastened it onto the 200 + year old wall. eight 3.5” lag bolts are screwed into the hard wood stud behind the lath and plaster wall. Yes, discerning eyes will notice a couple of errors – the top hole was drilled too close to the hinge and if you look close you’ll see a plugged hole where I mislocated a hole.
The mount plates are glued and screwed securely by means of a dado in the plate and good sized screws.
Lastly, the problem of holding the TV up while fastening it to the mount. I have a short step ladder and I made a temporary box that would sit on the ladder and support the TV while lining up and securing the little 4m screws into the TV.
Happy day! It holds the weight of the TV without any creaking or craking!
