As the back story, I just moved into a townhouse that has the living room set up for a TV mounted above a fireplace(smurf tube, coax outlet, power). However, I really hate having to look up at any significant angle to watch TV. The bottom of the TV would have been about 5 feet off the ground, if flush mounted with the top of the fireplace. Also, I actually want to use the fireplace on occasion, so the TV needs to be able to raise and lower, as well as tilt horizontally and vertically.
I was disappointed with the selection available for TV mounts with a vertical height adjustment. I either couldn't find one that would work, or it was outside my price range.
So decided to build my own. I'm attaching some pictures, and if there's interest, I can certainly provide any more info people might want.
Please bear with the clutter, marginal image quality, and unfinished entertainment center...
