I am replacing an old metal railing with a half wall at the top of our stairs. After framing the wall and putting drywall on, I noticed that the free end of the wall wobbles a little bit. I have searched for suggestions on how to secure the wall so it doesn't wobble, but most require that I cut into the floor, which I hope I don't have to do. The wall was made with 2x4's (see drawing). I secured the bottom plate to the floor with two 3" lag bolts between each stud. The free end of the wall has two 2x4's screwed together instead of one. I screwed an angle bracket with a 6" lag bolt to the floor on the free end (red/gray part of wall drawing). One thought that I had was to put a 4x4 on top of the free end using an angle bracket and attach it to the ceiling joist. Or maybe use some kind of support pole. Does anyone have any suggestions?

Hi, long story short - none of the walls are even, they are messed up but could be easily fixed and evened if they didn't have paint on it (I'm guessing that the patching compound just won't stick and stay to the paint), and getting the paint off will take ages if it is possible at all. Also the corners are messed up and looking ugly. Any ideas how to do it? I'll add some pictures below. [IMG]http://i.imgur.com/7G2peK4.jpg[/IMG] [IMG]http://i.imgur.com/PMdldiJ.jpg[/IMG]
