Installing Openings with Jacks, Headers, and Cripples

we need to square up the wall. Pull a measurement from corner to corner and be sure the measurements are the same. If you need to make adjustments, you can push or pull this framing and this helps square the walls. Essentially, all we do is move this wall in either direction until it's square. As these points get closer, the other points get further. So, when we put on our sheathing, our wall isn't racked either way. If we line up this corner and line up our long edge, we can use the edge of the sheet to square up our walls. Depending on how much your sheathing needs to overlap to go down and cover your rim joist. So, when this wall gets stood up, this sheathing will go all the way down and can get nailed into the sill plate. Subtract that distance and then we'll make a measurement up. And now we can use that mark to snap a line. We can line up the sheet on that mark. And you're going to want to install the rough side out. And remember to stagger your seams two bays. And nail down your sheet. If you don't sheet your walls before you stand them, your walls can easily move. Regardless of method, there's always an easier way. If you struggle lifting sheets, you can use a deadman. And this lets you adjust up and down, and then you can tackle one side and lift it up to your line. You want to be sure you stay on center. If this stud is bowed and you nail it, as you work your sheets up, now that this is bowed, your next sheet might not line up. So, when you continue your sheathing, this sheet will miss the stud. But if it gets done right, your next sheet should line up just right. Anytime you nail, you want to be sure you're not going too deep. If you go too deep, the sheathing will barely hold.
