Squaring up Old Partition Wall

[stoobydale]

Hi, what is the best way to level/square up an old wall frame? I have removed the lath and plaster from 2 walls and plan to replace it with Marmox backer board, however the existing timbers are not very flat across the width of the wall. I plan to screw cls to the sides of these but was wondering if this is the best method.
Cheers,
Stu.

2 x 1 slate batten fixed (screwed) at right angles (i.e. horizontally) to the studs at something like 400mm centres. Check the end of wall wall for plumb with a plumb line, 6ft level or laser level and pack out the laths until they run plumb from top to bottom. At each batten end then fix (screw) a short offcut of 2 x 1 slate batten, run a string line across between these two blocks, pulled taught over the blocks. Cut another piece of 2 x 1 slate batten a few inches long and run that along each batten in turn (this is a traveller). It should touch the batten and the string at all times. If it doesn't then pack up between the batten and the original studs where there is a gap. If there are any high points more than a couple of mm it may be necessary to pack out the batten at each stud by a little extra (in which case adjust the ends for plumb again). Repeat for each batten in turn. It's a bit painstaking but it works
