A couple of days ago I started this thread:
Which generated some heated debate. Basically I have an exterior wall along which is a shower, then the bathroom outside the shower, a hallway, then a closet. When I measured the dimensions of each of these areas, the north and south dimensions do not add up to be the same. Here is a sketch:
The hallway is the area delineated by points A, B, C, D. At first my inclination was to move points A and B west by about 3/4" which will even up the closet and the bathroom a bit more. After I posted the other thread, it was brought to my attention that by doing so I may be just making things more "parallel" but not necessarily square. Nonetheless I have already taken apart the stud from the bottom plate at point A, the north east corner of the bathroom.
Therefore my next task was to determine what is square and what is not.
This has turned out to be a rather complicated task in itself.
First let me provide a picture of the overall bathroom, showing the shower, bathroom, hallway and closet.
This is the west wall, edge of the shower.
This is the east wall, edge of the closet.
I wanted to determine if the west wall of the hallway (LINE AC) is square with the north and south wall AFTER I have moved the studs 3/4" west.
Due to the fact that that wall has a pocket door, with a door jamb, and the pocket door frame is a bit wider than a 2x, it makes it impossible to strike a line clean across all of them.
See this picture. I moved the stud at point A west and you can see where the bottom plate is.
I don't have enough room to do a 3-4-5, but I have a square and I used it against the south wall. The square seem to agree with the original unmoved point A.
Closer look at the square.
Now, if I move the piece of wood on the floor against the new line of the closet pocket door, which is hung from the position of the moved stud, the square is off!
That means the original LINE AC is square with the south wall, right?
So now I move inside the bathroom, and do a 3-4-5 against the south wall and the north wall, using the new position of the stud after I moved it. It SHOULD NOT be square, because that line wasn't square outside of the hallway. Well quess what, it is square.
I have a piece of 5' 1x2 and I marked 3', 4' and the moved wall is square with the north and south walls.
I am totally confused.
Now I have to admit, I was using a sharpie pen, and the width of the tip is like 1/4". May be the wood I used as reference lines are a little bowed? I don't know.
The fact is, each of these walls are not completely "cleared" they all have pipes, conduits furrings and other things touching the floor slab, and hence I cannot directly measure against it I have to offset a few inches inside and strike a line.
Is there a better tool to help me figure out what's going on? Will a laser level help me visualize what is square easily?
