Unhappy Need advice on window trim, jamb extensions

Im trying to trim my new windows on the inside (mitered on 4 sides), but there not even with the rock all the way around, it varies from needing 1/2 in. to nothing. I've looked at the diy tips and it says put on jamb extensions and plane down to flush. But how do I plane through the nails fastening the extension. On one side of the window it goes from 1/2 in to flush, that's alot of planing, and won't it look funny to vary that much?

Welcome to and the door/window forum. (I PM'd you before I saw this post)

Obviously something ain't plumb, and 1/2" in the 3 or 4 feet of the height of an average window, THAT'S SCARY!!

I want to know WHY THE DIFFERENCE??? Where did this 1/2" come from??

The windows (or at least the original windows) were installed against the studs in the wall, on the outside. The sheetrock was installed on the inside of the same studs. (Am I missing something?) Where's the 1/2" difference??

I installed new windows, ok that sounds bad, but there very close to level, plumb etc, within an 1/8th. I think the rock and mud is bad, but the window is in and trimmed on the outside. I would rather not take it out, I live in Minnesota, and its cold here allready. So, what are my options

Ran across this a few times in houses with old plaster.To build your boxed casing you want, you will need to rip each board out of square. When you slide it is it won't look as bad as you think. Ya it's out 1/2 inch but unless you want to feather the whole wall to make the opening straight I see no other option. Buy your wood 2 inches wider than you need ( or even just an inch ) and rip away.
