Dealing with bowed walls on your building projects can be a huge hassle.
Straighten existing bathroom wall by cutting bowed studs.
Just fix timber to the side of the existng studs to plumb up the wall.
The cut should be made on the concave side of the bowed area.
Cut the stud at the apex of the curve or the portion that most juts outward from the center of the stud.
The existing studs still do their job and the new timbers are use to plumb the wall.
The goal is to bring the low points to the high points with shims.
Essentially the two straight adjacent studs will help to hold the stud in an upright straight position.
Step 3 straighten and shim the stud.
It s not unheard of to do this more than once on a severely bowed stud say at 1 3 and 2 3 of its length.
With a handsaw or circular saw cut about two inches into the stud at roughly the midpoint of the bow.
Sistering can also be done to reinforce floor joists or rafters.
Next adjust the stud so that it s fully straight.
Expect some relaxation movement here as well.
When you ve located the site of the bow or curve in the stud use your hand saw to carefully cut about an inch or an inch and a half into the curve.
Out of alignment make a series of 1 3 4 in deep kerfs saw cuts every 8 to 10 in.
Gary the fix is real easy.
Apply force to the stud straightening it.
For the pieces that are bowed usually you can fix this by cutting blocking and fastening it between the studs like you mentioned but you will need to put a few in because if you just put it between the crooked one and the one right next to it generally you will just pull the other one out of place as well.
For example sister joists are sometimes installed to increase the load bearing capacity of a floor so it.
Toenail a 16d nail through each kerf.
So for your non load bearing walls with bowed studs cut a notch in the bad stud and then install a horizontal 2 4 brace to pull the stud back to a straight position.
If you ve cut the concave inset side of the stud.
In the bowed area with a circular saw.
As you nail the cuts will close and the board will straighten.
Push or lever the stud 50 past straight and drive a wood shim into the now widened cut.
I would start by plumbing each corners stud then sting a line at the top from each corner stud and use this as a guide for susequent timbers.
If you have a few severely bowed out studs that are more than 1 2 in.
