I'd seen this Instructable before, but didn't really have a need. Fast forward a bit, and I'm trying to figure out how to mount my 48" flatscreen TV in a corner. It has to come out at least 24 inches to provide space for the screen, so I was considering bolting a 2x12 across the corner, bolted into the studs...but I was worried about the downward force from the TV (it's not a NEW 48" flatscreen). This might work perfectly. I'm not worried about holes in the wall, so I'll probably screw a stabilizing 2x4 from each upright to the stud in the wall which should mostly be hidden by the TV.Thanks for getting my gears turning again!
