curved stairs


The curved stairs that I have built all start on paper. The start and endpoints are determined and the curves are drawn. Full size paper drawing can be made by the autocad or can be made the old school way with tremmel points. In the shop 2 curved walls are made to the exact radius needed for a wall stringer and an open stringer ( this would be a typical design). I make my open strg at 1"thick. So i will make 4 layers of 1/4" material, that way it will bend around the studded wall on pitch. I then layout my rise and run on the one piece of the 1/4" material just as you would do a normal stringer. I then tack this layer up on the forms and make sure to level and plumb the lines up perfectly. once the 1st layer is in place you glue on the other layers using strongbacks clamped level with the studded wall. Yes there are more little steps that I left out, but this is just to get the idea.
after a day unclamp and cut your lines with a circular saw, of coarse mitering the risers cuts on the stringers. The wall stringer if routed out with a dado to accept the treads and risers and a wedge from the back. This is routed out on a piece of 3/4" material...usually 1x12. it is then kerfed on the backside about 2/3rds of the way through to allow it to bend around the forms. Also hang this up on pitch on the curved mockup wall and glue on another piece of 1/4" material on th back to lock it in.

The tread are made off of full size prints made off of the autocad. A pattern is usually made for similar parts.

I can go into more details if anyone is really interested

all three of these are 100% free standing. Free standing could be a little tricky but can be done with the right planning,
Here are some of the recent ones i've built

en route will work. It doesnt have the capablility of autocad but for drawing waht you need it will work. So I take it you have cnc access?

Keith, These were actually built in 2006. What code are you referring to?

There was a code change from the 2003 code. I know because I built a set in the 1st quarter of '06 and got an inspector who was kind enough to point out the rule change to me and insist that I rebuilt both sides of the balustrade.

R311.5.6.2 Continuity.
Handrails for stairways shall be continuous for
the full length of the fl ight, from a point directly
above the top riser of the fl ight to a point directly
above lowest riser of the fl ight.Exceptions: 1. Handrails shall be permitted to be interrupted by a newel post at the turn.

I can't post any pics here but this is a link to one I'm just finishing.http://picasaweb.google.com/SeattleF...28929403348274

yes, we didnt have an issue with that one. Inspectors here in Mass are pretty lenient. To be honest, I dont know how some of the contractors get away with some of the stair designs ive seen over the years.

That stair is pretty sweet. How did you get the addition support in th middle where the window is. The stair in my 1st pic was similar to yours. It weighed a ton and had quite an intricate install. Here are more of the same stair. The second pic is one of the 3 sub stringers. They actually ran through the subfloor and attached to a header in a crawl space. Large custom steel brackets held up the top. Do you do these stairs for a living Keith?

David, what exactly is it would you like to know how to do?
