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

Wet the rock. Let it soak in for a while. It will bend around a pretty tight curve. Waste some pieces untill you have the soak time set.

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.
