TV Ceiling Mount

After buying a new flat-panel TV, I was facing the challenge to find a suitable TV stand for it. I couldn't find one that was aesthetical and practical, so I set forth to design an build my own. The result is this: a sleek, free-hanging TV mount.

The choice of materials and the basic design was partly a result of my limited access to tools. I strived to make the construction as simple as possible and use mostly off-the-shelf parts from my local hardware store. The only metal working tools needed to make this TV mount were a drill and a hacksaw. The TV mount was CAD-modeled so I knew how much material I would need to buy.
One main concern was to get the center of gravity correctly aligned beneath the main support truss. As it turned out, the center of gravity of my TV was relatively close to the geometric center and therefore I could roughly design the length of the two small horizontal profile pieces.

My starting materials were:

  • Aluminum profiles, quadratic cross-section, side length 23.5 mm, wall thickness 1.5 mm
  • 90-degree profile connectors
  • Profile end caps
  • Screws M8x50, M8x60, M8x30, washers, and nuts
  • Steel cable, threaded eyelets, cable clamps, carabiner
  • Concrete dowel
  • Spray paint (black, matte)
 Starting materials: aluminium tubing
The build started by cutting the profiles to length and inserting the 90-degree angle connectors. The hole pattern in the shorter mounting angles is 200x200 mm, or commonly known as VESA mount. All holes are drilled for M8 screws.
Partially assembled parts.
The next image shows the two shorter support arms. The hole is for securing the black plastic 90-degree connectors to the profile to secure the connection against the perils of gravity. The top part is not yet cut to length, as I was experimenting with the correct length to get the center of gravity of the final assembly right.

I could not get the right length of M8 screws, so I adjusted the length of the thread that protrudes into the TV with washers to the manufacture's specification in the manual.

Here I checked for the mount if everything works out the way it was planned. Looks good. The two short profile pieces still need to be cut to length. I adjusted the center of gravity by using the wiggle room in the screw holes.
Testing mount before painting.
The profiles were disassembled again, sanded, cleaned and spray painted. The visible screws were also painted for a coherent appearance of the final assembly. I used a matte black spray paint "rust stop" which adhered well enough to the bare aluminum. Without a proper aluminum primer layer, the resulting paint layer is mechanically fragile. As these parts will be used in my living room this is a minor risk but it saved me a bit of work & money.

The cables for mounting were made from steel cable and threaded eyelets. Having sharp wire cutters helps to get clean cable ends without fraying.

I attached the cables to the backside of the mount with self-adhesive cable tie mounts and routed the cables along the steel cable to the ceiling.
