This was a quickie taking place during parts of the last two days. The cabinet was getting a new flat screen to replace the old big body tv.
It was straight forward and the box had relatively square corners. The components will come out below the tv and be about flush to the face of the tv. The photos do not accurately portray the exact details of the process. I assume no responsibilities for anything!!! Shaz
These are the pieces of solid stock for this job.
This is the cabinet they wanted to put the flat TV in. The nice thing was that when the doors opened and folded back there was a smooth sided rectangle to apply the inner workings to.
This is the photo of the 2x4s that are edged joined and surfaced joined to get a true 90°. Then cut to fit the hole less 1/8". That allows for eliminating need to carry the miter box with me.
These two pieces will go in on the floor just behind the first mounting board I put in. Since I am raising the components up 1 1/2" off the cabinet floor, they will serve as a filler and as a solid support for the thin 5/8" connecting piece left in the mounting board at the bottom.
This is the first mounting board that I cut out of 3/4" birch plywood. See the thin 5/8" strip I left in the bottom of both holes? They hold the piece together at the bottom.
Since I needed good support for this Tv, which has a pullout and swivel bracket to be installed I decided to add the center vertical and wanted it to be as strong as possible. I needed 18" for each component. With the space left over, left to right, we had about 4 1/4". I went with 1" on the sides and 2 1/4" in the center, which meant notching the out side 2x4s and cutting down the center piece.
Notice in the second photo (or maybe the 3rd) how the center 2x4 is resting on shorter free standing short 2x4s? The short pieces were screwed into the ceiling and the floor. The mounting board was glued and screwed in place with 2" deerwood facteners (screws).
This is the final mounting board, pine plywood with pine molding around the holes, cut 1/8" short and 1/8" narrow.
Since the Tv will be pulled out and the pine will be visible I use alot of glue and 1 1/8" staples through the knots and pin nails else where. Also 1 1/4" screws around the perimeter as I have 3/4" coverage all around.
You see here the 2 pieces of 3/4" birch plywood that were set behind the first mounting board on the floor and also now there is the piece that will fill in front of the final board of pine. Attachment 16450
This is a floor that is cut to fit to be slid right in.
This was the determining factor for the placement of the two mounting boards as this had no tolerance for error and could not move left or right. Thus, as each mounting board was prepared to be attached this floor was inserted to be sure the holes lined up, then removed. Attachment 16451
This close up shows the hole, the notched 2x4, the 2 layers of plywood ,the 1 3/4" pine trim that covered the crack around the mounting boards and the 1 1/2" trim on the front of the double thick plywood floor. Attachment 16452
