Make your own tv swivel arm wall mount extension

Closeup of the box my swing arm came in.

I think these articulated swivel arms are mostly all made in the same place. They just put different names on them.

This is a VideoSecu ML10B. I thought I'd show you a big picture so you can see what you get.

Reinforce a plywood mounting area - you're going to be putting a lot of stress on it!

I added 1/4" plywood inside the cabinet - mounted the shelf on it - and added this panel on the outside too.

I used 1-5/8" screws to screw the purchased swivel mount to my homemade plywood extension arm.

View from behind - with strap hinges securely screwed in.

Finally I mounted the plywood extension arm to the cabinet with bolts and screws.

If you can screw into a stud, use a 3" screw. If you install into plywood, use bolts if possible.

I was able to "sit" the extension arm on my shelf, but you will probably need somebody to hold the extension arm for you (it's heavy!) while you mark the holes and drill for the bolts, or while you screw in the deck screws.

Notice that the heads of the bolts are on the inside of the cabinet - I didn't want long poky pieces coming into my shelf area (I'm going to keep sheets and pillowcases in the area where my huge old tv used to be).

Use washers on the inside, under the bolt heads, or your bolt heads will sink into the plywood.

7am on Sunday morning: I screwed that sucker to the cabinet!

Every single screw/bolt is taking some weight.

It turns out, I have to extend the tv to open the drawer! Didn't think of that beforehand!
