Thanks for all the feedback... it's a corner wall I want to go around, the rock is 8' long and will be 14" high. I do have a weight lifting bar I could lay between two bar stools, or maybe two broom handles spaced apart and wet it. I have enough extra rock that I can cut from both sides to have a nice edge along the top. I'd like masonite but it's an exspense I'd rather not get into. I want the bend to where I can run an 18" radius 3-1/2" from it.
For the bend I've used both wet sheetrock and masonite with equal success. The flex bead is the way to go to finish the edge either way.

When I was rebuilding my house, I used 16 foot lenghts of sheetrock on both the ceiling and the walls. When I had it delivered, the guys carrying it into the house had to make a 90 degree turn to make it between a closet and a stairway.
They did it without breaking it ! Not even one single crease.
At 16 feet long, believe it or not, it is very flexible from end to end. So depending on how sharp your curve is, you might be able to bend it without wetting.

Alan is right.
Wetting is the way to go. A few years ago I wired a large addition to a church. It had some curved walls and arched ceilings. The rocker was incredible. It took three days but he bent 1/2" firecode rock into beautiful tight curves over wooden forms. Not a bump to be found.
The forms are the key. Find some cylinder of about the correct diameter, and lay the sheetrock over it. Wet gently and do not force it. Let the gravity create the bend. You can weight the edges, but start gently or it might break. Keep it damp and after the curve is in place, let dry then lift GENTLY into place.
Notice the key word?
Good luck.

I thought of scoring the back about half way through, moving the steel ruler over an 1/8 of an inch and scoring it again at an angle and taking out that strip. Doing that about an inch apart for twelve inches, it's for a 14" backdrop and the rock is 1/4". Thanks,
Thanks,
It will just break all the way through to the front paper coating if you try that. All you will have is a thin paper sheet trying to hold everything together (very fragile). You are better off bending (with wetting) two layers of thinner drywall or using 1/8 hardboard (several layers if more thickness is needed). I would just just hardboard (Masonite) and make the front surfaces match up with the flat drywall sections.
