All Ledger Boards Up

I installed the last of the ledger boards today. I've been using a laser level to ensure that everything is straight and true. During the daylight hours, the laser will show up fine when you are within about 12 feet of a wall. The problem with that is, when you are that close to the wall, the laser line isn't wide enough to extend the entire width of the basement. But, if you move the laser farther away from the wall, it becomes impossible to see. The solution is to wait until it starts to get dark. This picture was taken about 4:15 in the afternoon. By that time, it's dark enough to see the laser all the way around the basement; and I can get a much better idea of how level everything is.

You can see the laser line at the top of the ledger boards. It's important to check the level and alignment at the top of the board, rather than the bottom, because the boards can vary in width by up to 3/16". If you align them at the bottom, they may not line up at the top. (I learned that lesson the hard way.)
