drywall onto uneven walls?
 
My home is from the 1950's, it's a "panel" home I guess... It seems to have been assembled from offsite built 5-foot or so wide sections of 2x3 studs. It has like a 1/8" or 1/4" plywood nailed AND glued to the studs on the interior AND exterior.

I've been stripping the interior/exterior plywood and the glue makes it a nightmare. You never can get it off 100%. You are left with some studs bare, some with small strips of glued wood.

I'm worried that this, combined with just general lousy tolerances of the "panels" will make for trouble with new drywall.

But... there was drywall on there to begin with, so it must be possible? What kinds of offsets in the studs can you get away with before it (or I) starts to crack?

the problem will show when trying to screw in the screws... if the backing is hollow... the screw will crack the drywall... it will affect only the area of the screw... but that means the screw becomes a phantom screw and offer no support for the drywall.. and you need to find another support spot nearby... this type of issues will waste you time at installing/mudding phase... so the best is to scrap out every uneven part up front to save the headach later on...

I had a similar problem with one small section of a wall where the screws kept popping through as the studs were uneven. I opted to use a plaster repair hardware kit for the 2 sheets of drywall. It's basically a 1 inch washer that is used in conjunction with the drywall screw and distibutes the pressure over a larger area so the screw doesn't pop through. I'm not sure if this is "the right way" to do it, but it's been 2 years and no issues, and it's on an outside wall.

The stud itself, vertically, is pretty much all in the same plane

the problem is the studs may sit a bit in/out as far as the horizontal spacing between the studs. We're talking, I dunno, 1/4" between a 16" span?

If you have the time and inclination, I'd considering "sistering" your studs with new, straight 2x4s. In other words, you'd be nailing a new stud |||| right to the old one, and by doing this, you'd be able to make sure that all of the new stud faces would be in the same plane. Then you'd have no problems hanging your new 'rock.

You might end up losing somewhere <1" in room size just by the nature of this "evening" process.

Hope this helps!

in this case, the drywall probably won't break ... but the wall will show waves effect and doesn't look nice when finished.... got that in our living room ceiling from the builder...

like everything... build from scatch sometimes has less headache than fixing....
