Hi everyone. I've been away for awhile, life changes and such . I'm settled into my new place in Little Switzerland now and I want to add an outdoor TV in my pavilion. I've purchased an electronic ceiling mount for the TV. The idea I have in mind is to install a ceiling mount on a swivel that I can turn 180 degrees depending on where people are sitting. The mount and the TV weigh approximately 70lbs. I've found a few raw ideas on the internet on how to make a wooden swivel, but I know there is a lot of knowledge here and great woodworkers that might have a better plan to make a swivel. I'm open to all suggestions. Thanks in advance.
