Need advice on "hanging" a flat panel TV in a cabinet
I've just finished the carcass and face frame for a 84"h x 67"w built-in entertainment cabinet and now need to construct a small wall in the TV section of the cabinet to hang a 52" flatscreen TV. I'm hanging the TV because I want the face of the TV flush with the front edge of the faceframe, then I'll trim it out with speaker grills on the side and a trim piece on the top.
My plan is to build a 34"h by 24"w stud wall with two studs 16" on center and two studs at the ends that fits tightly in the TV section of the cabinet, then attach the top plate to the top of the tv section (2 sheets of 3/4 birch ply laminated together) with 2 1/2" lag screws and attach the bottom plate to the shelf (also 2 sheets of 3/4 birch ply laminated together) with hex bolts fastened to nuts on the underside of the bottom shelf inside the lower cabinets.
To build the stud wall I'm thinking of standard stud wall construction but since it will be built outside the cabinet I'd build it by screwing through the top and bottom plates into the top and bottom of the studs with 2 1/2" #12 screws (2 per stud on each end) and using glue to help strenthen the joints.
Does this seem like an adequate design to support hanging a 60 pound TV? Should I add heavy duty L brackets to make it stronger?
(I'm having a professional installer install a flat screen mount to the wall and hang the TV).
Thanks for your help,
