DIY Flat Screen Corner TV Mount



Introduction: DIY Flat Screen Corner TV Mount

About: I'm a husband, dad, contractor, woodworker, tinkerer and all around busy dude. That said, I put projects out when I can. A weekly basis is a dream that one day I hope to attain. I love making things, buildin…

We rearrange the rooms in our home more than I would like to admit. And a few weeks ago I was tasked with moving our flat screen TV into a corner. It had to look like it was floating. I'm too cheap to spring for a fancy corner TV mount, so this is what I came up with.

Step 1: A Simple Drawing and What You'll Need.

Above is a simple drawing of the flat screen corner TV mount I build in this project. Keep in mind that the TV and cheapo TV mount you're using may affect these dimensions if you decide to make this project. Measure twice, cut once, you know the drill. Now here are the things that I used for this project.

What You'll Need:

  • A cheap tilting flat screen TV mount.
  • A TV
  • Framing Square
  • Marking Pen
  • Long Straight Edge
  • Measuring Tape
  • Table Saw
  • Skil Saw (I don't have a miter saw at my home shop, YET.)
  • 3/4" Plywood
  • Wood Glue
  • Air Compressor
  • Finish Nail Gun
  • Cordless drill
  • Impact Driver
  • Screws

Alright, now that that's all out of the way. Let's mount a flatscreen TV in the corner on the cheap. DIY style, even.

Step 2: Layout Your Flat Screen TV Corner Mount.

I used my workbench to layout the TV corner mount. The 90-degree angle on the edge of the plywood represents the inside corner where I'm mounting my TV. So this lets me generate a quick 2D plan view of the mount so that I can make sure everything is going to fit. You can do this on a computer too, It's just quicker for me to do it like this.

Step 3: Rip Your Plywood.

Then I ripped my plywood to 14" strips. These would become what I use to make the corner mount. I used 14" because it was a little bigger than the tilt mount I was using, and I could get 3 rips out of one sheet of plywood with a little bit of waste.

Step 4: Cut Your 45's.

Then I clamped a straight piece to my strips, using that as a cutting guide. And cut the 45-degree angles I needed to put this thing together.

I have 3 miter saws at my business' workshop, but not a single one here at home. And my table saw doesn't work well when it's mitered this far. It's old and worn out, long story. So I had to make do with what I had.

Step 5: Cut Everything to Length.

Then I cut my pieces to length on the table saw sled. It would have been nice to have one of my big miter saws, but as those crazy Canadians say, C'est la vie.

Step 6: Put the TV Corner Mount Together.

Then I glued and tacked the corner TV mount together with finish nails. This just holds the pieces in place so that I have time to predrill counter sinks, and mount the whole thing together with screws.

Step 7: Oops.

I goofed up. I forgot to deduct the thickness of the mount and TV, so now this thing would be 8 inches from the wall on the sides. So I cut the extension panels down, so that the TV was only 1-1/2" from the wall when mounted.

Step 8: Finish Putting It Back Together.

Then after I made my adjustments, I glued and screwed the face back on. I was extremely surprised with how strong this thing was.

Step 9: Attach It to the Wall.

As you can see in the video above, I had a little technical malfunction. But this step is simple enough.

Find your studs, predrill through the corner mount into them, and mount this thing with screws. I ended up putting three 2" screws into each of the studs.

Step 10: Test It Out.

It wouldn't be a complete strength test unless you got up on the thing, right?

Let's just say it's pretty solid.

Step 11: Mount Your TV.

Then I attached the cheapo mounting bracket with some pan head screws, making sure they were short enough so they didn't shine out the back. After that was done, I threw the TV up on the mount and all I had to do was hook it up.

Step 12: Plug Your TV In, and Enjoy Your Favorite Programming.

Now all I need to do it come up with a way to hide the cords. I'll probably make a chase in the back corner painted the same color as the wall.

Thanks for checking this out, and I'll see you on the next one!
