I want to mount a TV using a basic TV mount. I do not want to mount onto the exterior wall and the back roof truss does not have a joist hanger so I can't use a side-facing TV mounting plate.
The two blue posts bear the load of my roof and are 4x6 (4x5.5). What is the proper method to attach a horizontal board so I can then mount a TV mount to it?
I was thinking of using a 2x10 (so when I mount the TV mount the bolts are at least 2" from the top and bottom edges) and attaching them to the inside-facing faces using joist hangers. I'd likely use 10D nails to connect joist hanger to beams and 10d 1.5" nails where the hanger connects to the horizontal board. Any ideas or thoughts are much appreciated!
