Shoring up a load-bearing wall
When I need to install a header for a new window or door in a bearing wall, I shore up the wall with a temporary row of angled 2x4s alongside the existing wall. As shown in the drawing, the temporary wall bears on top and bottom plates that are screwed to the ceiling and floor. After the plates are set, I wedge 2x4s that are a couple of inches longer than the distance between the plates into the pattern shown in the drawing. I drive a nail through the base of the first stud. Then I persuade the rest of the studs into position. This action doesn’t take a lot of force, but the studs should be tight to one another.
The last stud gets a nail through its base into the bottom plate to keep the row in place. This system works well for me without wasting any studs, very few nails and a minimum of installation effort.
