Okay, back with more questions.
Now that I have the walls all cleaned out I need to run an electric line from one wall to another. I'll just drill through the studs for most of it but the corners of the room are a little funny. They are made of what looks like 4 2x4s. I've included a link to a picture for reference. http://i1108.photobucket.com/albums/...rst/corner.jpg
Well there is definitaly no way I can drill and run a wire through that. I've been thinking I will just need to notch the boards and run the wire through the notch but I figured I'd ask if there was some standard way to solve this problem.
Second, one of my walls is an exterior wall and has a large header at the top (2 2x4s stacked on top of each other). Where the studs meet the header the header sticks out to varieing degrees. Some places only 1/16th while probably over a 1/4" in others. Do I need to shim these flush before I attach my drywall?
