I searched the forum and did not find quite what I need, but his thread was the closest, so here is my problem:
I just bought a new home last fall, and am finishing my basement (learning as I go). I now need to make and install window jam extensions for my vinyl (Anderson) windows. I have found several sources discribing how to prebuild a picture fram or box. While these discriptions mention that the depth from drywall to window should be even, mine are not, with up to a 1/4 innch variance from top to bottom, and there is not room to add an additional "shoe plate". I barely know how to run a table saw, moreless rip boards on an angle. Is there a simple (or not so simple) solution? [Or do I need to call my builder to fix (rehang) the windows?]
Thank you for your help and insight in advance.
