Drywalling a curved surface...
I am building some curved soffits as part of a basement remodel and would like to have a curved vertical face at the corners instead of a right angle. The soffit would be about 8" tall.
Before I construct the frame for the soffit I want to figure out the radius for the curve. I plan on using 2 layers of 1/4" sheet rock.
Anyone know how much an 8" wide strip of 1/4" sheet rock will bend before breaking?
I am also interested in any ideas for constructing the backing. I was thinking of using 3/4" plywood for the top and bottom pieces to establish the radius with blocking in between to fasten the sheet rock to.
Thanks,
DavidJ

The book I have on drywall construction indicates a minimum radius of 2 feet for 1/4" drywall, wet. It also says to wet only the side of the panel that will be in compression and to space the studs at 6" o.c.
For 1/4" drywall applied dry, they give 5 feet minimum radius if board is applied with long dimension perpendicular to framing or 15 feet if long dimension is parallel to framing.
Hope this helps.
