hello. i'm starting the infamous "basement project". for starters, the floor is not level. The house if about 45+/- years old. It's not on a huge or uncomfortable pitch, but the floor leans slightly to the floor drain.
What I'm wondering really is where the 3 floor support posts are under the main joist the concrete raises to meet the concrete pedistal the post sits on. Should I just frame that wall with a second 2x4 underneath to compensate? And, do you understand what I'm asking because I'm a novice at this?

If there is going to be room for a second 2 x 4 much of the way, it might be the best way. A 2 X 4 will bend some. You could take some of the gap out be using different length studs. Go too far that way, and it will be difficult to flip the framed up wall into position. The wall won't be bearing any weight, so a few gaps will be OK. Just make sure you have plenty to nail a base board to.

Cool. That's what I was thinking, I just didn't know. I wasn't sure if I should cut the sheetrock to follow the floor line then, too? Obviously gonna want to put up some baseboard to cover things up.

Caulk and trim are the carpenter's best friends. Get the 2 x 4's close, the dry wall might better have a little gap form the floor to keep from drawing damp, and a base board to hide everything.
