I have one of these hanging chairs I want to put in my living room so it's crucial that I install it where it's going to support a lot of weight. I live on the top floor of a brownstone built in 1901 so the ceilings are wood lath and plaster. My stud finding has been useless in helping me out at all so I decided to drill small holes in a large square section (about a 2 feet) of the ceiling to find a joist. I drilled about 24 holes in two axises (one every two inches) and every single one resisted at first and then popped through. I'm not going to cut a big hole in my ceiling to peek up there and I'd rather not make my ceiling look like a cheese grater by drilling many more holes (or banging in 3" finishing nails). How haven't I hit a joist? Is it possible that I don't have any as the only thing above me is the attick (which I don't have access to)? HELP

I decided to build a wall between my dining room and living room. There was already a 1 ft divider coming down from the ceiling, so I framed the wall to attach to this, and to lower it another foot. Everything went well, it's framed and the drywall is up, but now I have some problems I've run into: 1. The original wall divider was rounded at the edges, so I have a small gap between the rounded edge of the existing wall and the square edge of my drywall. Do I just mud the gap and carry on? 2. Do I have to do anything (sand, etc.) the existing walls in order to mud and tape the corners where the new wall meets it? Or will I be OK just mudding and taping? The walls have the orange peel texture to them and are already painted. 3. Do I use corner bead on the inside and outside corners? I saw an item at Lowes that looked almost like a metal corner bead, but it had tape attached to it. Could I use this instead of having to screw the corner bead in? Which would be easier? Can corner beading be used on the outside AND inside corners? And I do want to apologize if I haven't describe this correctly. Any help and/or advice will be greatly appreciated! :)
