I'm working on a basement remodel and actually going with the FHB article suggestion of using steel studs sistered to the joists to level the ceiling for drywall.
Its a 1920s house and the ceiling area I'm working on has a 12' span with 1x8s on 16" center. I need to remove one of the cross braces between all of the joists because they interfere with sistering the metal studs. The bracing is just 2 2x4s toe nailed crosswise to form an "x" between the joists, set halfway of the span. I'm hoping the with age of the structure (not a whole lot of settling) and the fact that all the spaces b/w the joist where they rest on the foundation have long since been filled in the mortar, that there will be no movement when I cut out the braces.
