Hey guys quick question.

My father in law has my old Sony Bravia tv, it's 55" and weighs 40lbs.

He wants to wall mount it on a plasterboard wall, smack bang in the middle of two thin wooden beams, that are 6 feet apart.

And he wants ME to do it.

Tell me I'm right in being a little, let's say concerned, here

Half inch plaster board has a pull down weight of about 40lb per 12 inch square. But would it REALLY hold this tv? In the middle of the damn section, no less...?

I have a feeling this will crate a new port hole into his kitchen more than anything. Maybe if there was a central beam I would be ok but just on blank plaster board?

Any advice gaffing peoples?

I found these things a few years ago called Ghostuds. They're rated for like 200lbs so I originally used them for a series of towel bars. I then mounted a 60lb tv with them and they've held for a couple of years with no issue. I would imagine doing it without them would put a large hole in the wall.
On a side note about the towel bar: when my daughter was 8 or so, she was using the towel bar to do chin-ups and they are still solid on the wall.

Maybe you can do a cross brace/beam connecting the studs and mount to that, depending on how picky your father in law is with appearances.

I think I'm understanding your question. Current request would not allow for stud mounting?

If there is six feet between the two beams there is almost certainly going to be studs in there. Use a stud finder, mark the studs and use the hardware included with the mount. Studs are generally every 16" so there will be at least three in there to use.

I say "almost certainly" because in my years of contracting work you DO come across some half assed shit that isn't done properly so you never really know. That's why I say get a stud finder and mark the studs and go from there before you start looking into all these different drywall anchors. Right into the studs is best.
