Curved Stairs

fpro

You had mentioned every 16", but I think I may have to have it spaced more closer say 10"-12". The curves are really steep. Did I mention it turns 180 degrees? Especially the inside stringer. I think I will need to cut the rock into pie shapes. I was hoping to template the entire turn but I don't think that will be possible. The smaller pieces will mean more seams but will be easier to manage.

Will do. Thank goodness I don't have to pay for all this invaluable information. What a great place. Thanks guys!!

Another option for these stairs would be plaster, if you have access to a good plasterer.

closer spacing will not hurt. We have dampened the back of 1/4" with a spray mist and bent around a 12" radius. I believe they make flexible 1/4" for bending purposes.

Worth a trip to a real
drywall supplier.
Never thought of the steel studs.
Wasted a lot of time building up
laminates from 3/8 " ply rips to
get the "twist factor."

That's what I did today. Went to a local building centre and picked up flexible 1/4" sheets.

Nice! Don't forget to get pics during the process, if you don't, you'll regret it later.

Just wondering.....why don't you have the drywall co. come back and pay them to do it?

fpro

Job too small for them. Not worth their travel and setup.

loneframer

fpro, whats the news? Did you get started on those stairs? We want pics, please.

Ok, here are some pics. It's not complete, but it's coming along.

The curved drywall is 1/4" material and after it's been wet, does yield. Although, instead of using a second sheet to cover the first I think I may resort to plastering it to the finish stage. The section of drywall I cut were using a card board template. If I recut the same pieces they will inevitably end up on the same seams, which will cause more work after trying to get those seamed areas down and covered evenly. If I plaster I can build it up to teh 1/2" stock and eventually even it out cover al the seams nicely. Anyway that's the plan...

Here are the pics so far.

Wow! How in the world did you curve the oak like that? Wouldn't thin MDF work better than sheetrock if you are just going to plaster it anyway?

fpro, that looks very nice. I see what you meant by the steep angles on the curve now. Looks like the metal studs performed well in that situation. You might be better off with the plastering idea, that is asking alot of the drywall alone. Please post a thread in framing forum with details of how you utilized the metal studs, not everyone looks in the drywall forum. Thanks, looks awesome.

I did the taping on a staircase like this 10 yrs ago ,they used masonite instead of rock ,we coated with durabond a couple times then plus 3 or some topping mud .I got a feeling that after a few years of bouncing steps and dry wood it's gotta be cracked up.They should've used 1/4"rock.

AARC Drywall

When doing curved stairs, we use blocking every 12" oc, and to get your curve use polly and staple it to the curve you want to create, make sure it is tight, and firm, trace the stair angle to the wall on both sides using a marker, While you are doing this, make sure you have a 12' sheet 1/2" soaking in water. Remove the polly making sure you know which end is up. and trace onto the drywall laying flat. Cut out and install. some triming will needed to be done, and if you dont feel confidant it will fit, might be to narrow, add a bit to our lines.

We have done many, and this is the way we do it, and it works well.

If you have the time and inclination, I'd love to see some pics of that process the next time you do one.

I recently did something similar - a corkscrew-shaped wall in the tunnel for a skylight. The lite was one rafter wide, but the opening in the ceiling was to be two rafters wide, and not centred on the skylight - so one face of the tunnel was between the upper chord at the4 skylight and the bottom chord of the next rafter over, creating a continuously changing angle between them just as these stairs.

So, since we're on the topic, I made a thread in the drywall pic area just for fun:

Since a lot of the work is the framing, maybe I'll post a link to it in there too.
