It looks like a TV swivel is simply some wood with a lazy susan in between.....correct? I just need the lazy susan.
I tried the 12" Home Depot (1000lb rated) lazy susan. The weight is not the problem. The problem is that I need a larger surface area for the lazy susan since the corners of the wood which the TV rests on is almost touching the bottom stationary piece of wood. Since I am already using 3/4" MDF, I can not get a thicker wood to solve the sagging corner problem, so I thought if I got a larger lazy susan with more surfadce area (ie: not 12" rounf, but possibly 15" round), then that would help with my sagging corner problems...
Basically, the TV sits on the rotating piece of wood and poart of the TV sits where the lazy susan is not directly underneath, so the corners are sagging.
