Ledger board for TV wall mount
I wanted to mount my new tv wall mount but my studs are 24" apart. my TV wall mount is not that wide, so I decided to cut, paint, and mount 2 28" pine ledger boards on the wall to the studs. I don't like the big ugly lag bolts that come with the TV wall mount, so I decided to use the Spax lag bolts. These things are fantastic.

Heavy duty and they screw in wonderfully.. very simple to install. Much better then the old way of drilling holes for lag bolts or running the old lag screw style in.
