I am a reasonably competent do-it-yourselfer. My wife and I are in the process of converting a duplex to a single family dwelling. We need to put an opening through one of the existing “separating” walls. It is a double stud wall, so the opening will be seven inches through (plus drywall on either side. Existing is 5/8″) The opening will be a typical 6’8″ x 3’0″ with the top arched with an 18″ radius. Now to the question. How do I bend the sheetrock into such a sharp arc?

Get it wet.
That was easy enough. Thanks
With 2 or 3 layers of 1/4" Moisten with a spray bottle.

Hello All,
Just came in on the arch conversation.
I recall National Gypsum making a "flexible"
1/4" drywall a few years back.
Saw a demo where it was moistened and rolled
tight enough to get it into a drywall pail. Impresive.
It might be worth looking into!?
Good Luck.

I've never used it, but I was curious so I went to the National Gypsum site.
Your recollection is correct. Here it is: http://www.nationalgypsum.com/products/?query=cat:1&product=8
Hey, thanks! I still want to see the photo of
it in the bucket tho! :)

for a tight bend that won't crack helps to cut your strip of drywall a day or 2 before if you can and leave it leaning so that it'll start the bend on it's own...u can help during this time by adding moisture... always start long ie... if it'll take 60" for your arch use a full 96" strip... make your arch then fit/add the bottom to each side down to the floor....
good luck

coming in here totally out of the blue but wouldn't an arch 5 or 6 feet wide be better for joining two different living situations into one?

2 layers of 1/4" drywall or plaster
When making drywall arches, I usually Jerry-rig a jig to hold the ends of the workpiece up in the air with enough space below to allow it to bend the required amount -- mud buckets, sawhorses, whatever works. I then spray it with a garden sprayer (convex side if it's a small curve, both sides if it's tighter) and let it sit while I go about my business on other stuff. Spray again every once in a while as needed. The weight of the drywall will cause it to sag and you'll have an arch in a few hours or less.

Take your t square and cut 2 strips the size you need from the end of a board. Cut the rolled edges off and flex the pieces a little. Start at the center or top of the arch and press each piece to fit against it. You'll have a joint at the top and at each side but that's not a problem because it all gets mudded in. Drywall doesn't bent well when you rip it, only when you "crosscut" it. Kinda has grain like wood.
