    Default What size studs to use?

    Hi guys,

    I recently bought a Queenslander which I'm looking to renovate, by means of altering the layout. Given the construction techniques of the time, the walls comprise of 75x75 hardwood studs, lined with VJs (and no cavity).

    I'm unsure of which size studs to use (70x35 or 90x45) to best match to the existing 75mm studs given the 70mm is thinner, while the 90mm is wider.

    What's the norm?

    Cheers!

    could go 70mm and use some ply bracing to stiffen it up. Doubt they are all 75 x 75 prob 75 x 50 or 38 ,, anyway some of the old studs will probably vary form 75 to 70 anyway.

    Sounds like a reasonable suggestion. I guess what I'm more interested in is, how could I extend a current wall, ie. do I:
    - get rid of the 75mm original stud wall and just rebuild with new timber studs (width of my choice), or
    - leave the original wall and just put the 90mm studs in between, so the original wall would pretty well be inside the new one, or
    - something else?

    Sheeting over something with that sort of discrepancy in width is going to show, right?

    could put 90mm in between.. Ill bet the walls arent perfectly plumb so doing that could straighten the wall up. Have to be careful removing walls in a qlder..most carry ceiling joists and/or roof struts.

    Buy the 90s and rip down to size...not hard, circ saw and fence...

    Had to do metres and metres of it... The Old Cottage was a bit random stud wise, so I ripped to match what was next to what I was doing...
    And.....your point is.....what exactly?

    Plus belt sander and/or planer to get them to correct size.

    Yes, a lot of work, but old homes are a lot of work if you want to do it right.

    And when buying timber, measure it and make sure it is straight, don't take any old rubbish, because as a one off, the yards will give you all the krap that everyone has knocked back.
