Talking the GC into having a groin vault ceiling was easier than I expected. I showed him the JLC article about it, and he said, "Yeah, I like it, let's do it"
In fact I got more than I bargained for. I was only suggesting putting one in the dining room, but he wants to put one in the master bedroom, too. I have my doubts about that because the master bath door is in a wall that cuts into the room at a 45 degree angle. I'm not sure I could make that look good. Could I? I think its better to stick with the tray thats on the plans.
But here are my questions.
First, the dining room is slightly rectangular. The article I saw had the same situation, but the carpenter kept the vault square. I'm inclined to have the soffit uniform around the room and have a rectangular cross vault. Any opinions on that?
Second, today before leaving I quickly marked out on the floor the corners if I had a 12 inch soffit. That would give me 17' 4 diagonally across the vault. That's more than eight foot for my hips... I might be able to make the soffit bigger, but I really want to know how you pros would go about making that hip longer than 8'? Nail and glue the plywood together?
Third, it appears that the hips in the article are drawn with a constant radius. It strikes me that if two barrel vaults intersected each other, the hips would actually be elliptical?? And that there really shouldn't be need for a bevel cut on the 2x4's he frames the ceiling with. At the same time I wonder, if I'm right about this, it still might look better to do it his way? Any feedback on this?
Oh yeah one more. He builds the soffit with what we call a chicken ladder on the bottom (horizontally), a piece of 3/4 nailed to the side, and a 2x4 nailed to the ceiling joists at the top. Is this sufficient, or would there be a better way to frame it?
