Continuous curved central cut strings give a very elegant design for modern stairs, but the curved stringer and handrails can be long and expensive to manufacture.<\/p>\n

A compromise is to make the string and rail in straight sections bolted together.<\/p>\n

The handrail is assembled around newel posts and there’s no need for wreathed sections.<\/p>\n

Using horizontal laminates, this sort of stair can be made by an amateur woodworker although I strongly suggest that the plans be drawn up by someone with experience in this type of construction.<\/p>\n

Here’s the plan of a stair that I have just completed for an amateur stair builder:<\/p>\n

\"clip_image002\"<\/a><\/p>\n

StairDesigner can’t construct the straight strings so it’s DXF files have to edited in CAD to get the straight extensions.<\/p>\n

Here’s the original Stair Designer project :<\/p>\n

\"cut<\/a><\/p>\n

Note how I use an outer boxed string to simulate the lower railing of the left hand balustrade.<\/p>\n

To see how to do this have a look how the parameters are set in the StairDesigner file you can download below.<\/p>\n

You can also have a look at this article:<\/p>\n

How to Design a Wooden Handrail for an Existing Stair with StairDesigner<\/a><\/p>\n

The stringer and the handrail are modified using ProgeCad.<\/p>\n

Here is a rough out of how the string will be set on site with the straight sections :<\/p>\n

\"clip_image004\"<\/a><\/p>\n

And this is a rough rendered view of the stair :<\/p>\n

\"central<\/a><\/p>\n

\"3d02\"<\/a><\/p>\n

\"3d03\"<\/a><\/p>\n

 <\/p>\n

The strings will be built using horizontal laminates.<\/p>\n

For more details you can download all the plans<\/a>, including the plans of the laminates.<\/p>\n

You can use these files to make the stair as is or modify to suit your dimensions.<\/p>\n
