Hi Adamd,

Can you start a new topic and give some more details about what you are planning to build.

That makes it easier for us to follow through your project with you and help you if you need it.

All the best,

Stefan

Hello Ness, I checked it is very nice design. I will follow this for making stair in my house.

Can you show me more design. It will be very helpful.

Thank You.

Hi Steve,

 

I usually set the stair up roughly by eye and then adjust to the absolute angle.

It seems that this time I forgot to correct the angle of the steps to put them precisely at 0° and 90°.

So here are the corrected files.

The string board dims are the smallest rectangle. In general you will set the string out by assembling several boards.

I have drawn a possible board assembly the dwg files I have added to the parts folder.

The best thing to do is to redimension the separate parts the curved gussets can be glued on later.

Note that StairDesigner doesn’t draw the cut string top post assembly lines but will draw the strings upto the theorectical position of the next cut string.

To show you how this works, I have drawn in the exact assembly lines on the parts dwg drawings.

Sorry about my mistake on the step angles.

All the best,

Ness

 

hope this is helpful

Hi Ness,

Thank you very much for the design templates.

I am not familiar with the conventions used on some of the drawings and would like some guidance please .

The printed sheets show angles for each tread 0.00 for the first step, -1.86 for the first landing then 0.16 for step 3 decreasing to 0.02 for step 10.

However, I am not sure about which axis the angle is bieng measured and what units are bieng used to measure the angle. I assume the angle is measured in a plane perpendicular  to the nose of the step and is in degrees, but would like to be certain.

Lastly, the ‘right string board 2’ is given as Dimensions 3930 x 656 are these the dimensions of the smallest rectangle from which the ‘S’ shaped string could be cut and also, between which points is the angle 34.2 degrees measured?

Kind regards

Steve

Hi Steve,

Here are the plans of your stair.

Hope you have fun building it.

Keep us updates as to how it goes.

All the best,

Hi Ness,

I like it, that’s spot on, we will go with that.

How do we proceed now?

Kind regards

Hi Steve,

Here’s a design with a post on the right.

post-under-landing02.pngImage Enlarger

 I would suggest that this design works well and would not myself make a cut string on the right of the landing. I would leave the boxed string and add the handrail with balusters assembled into its upper edge.

You’ll need to design the details of the bull noses in CAD if you machine with CNC or directly onto the printed templates if you build by hand.

All the best,

Ness

Hi Ness,

Sorry the attachment did not load, although its smaller than the limit, so I have put it in the dropbox link in post 6.

Kind regards

Hi Ness,

Thank you very much for the improvement, it looks good.

There is going to be a rail at the end of the first landing, to match the other rail on the left. I thought a newal post would be needed under the right hand end under the landing to match the one on the left. A matching bullnose to the right of the first step as you suggest on the left would complete the stair.

I have made a rough sketch Image 12 attached.

Kind regards

Steve

Hi steve,

You already have a post under the 1st landing.

I would suggest that :

– the handrail start at a first post on the landing  

– that you make the first step with a bullnose or curtail.

– that the lower string shape be adjusted

Hi Ness,

I like the last design stev01v03-3d01.png. I won’t bother with the complications of recalculating the stairs this design is fine.

The only addition I can think of would be a cut off newal post under the lower landing (step 2) on the right to take the continuous rail post.

Just to anchor the end of the rail.

Kind regards

Steve

Hi Steve,

As the steps are joined to the risers they will not bend but aesthetically they would be better a bit thicker.

I wouldn’t bother putting another stringer.

In the actual version of StairDesigner you can’t make the right string into a cut string.while leaving the other right strings boxed.

You can however add a cut string to the right hand side creating both boxed and cut strings on this side.

You then just ignore the inappropriate parts in the plans and cutting lists.

To put a cut string on the right you have to give a negative offset equal to the thickness of the string ie:-32

The 3D model  will not display the cut string as it’s mixed with the boxed string.

You can see it if you turn the boxed string off, however turning it off will recalculate the stair and you’ll have to set up the landings etc again.

the images below show both the string board and the cut string in the manufacturing documents.

All the best,

Hi Ness,

Yes that design is much better.

I wondered if the steps would be thick enough not to flex with two stringers  and have bought enough timber for an additional stringer up the middle if you think it would help.

I am still having trouble making the string on the right of the first step into a cut string.

Kind regards

Steve

Hi Steve,

You stair looks good.

I would tweak a little bit you design :

  • putting the posts under the steps so that the landing steps are not cut by the post and the upper handrail post can be just assembled onto the landing
  • move the nosings on the landing steps so that the risers are not too near the face of the posts. This will make housing them into the post easier.

The only other point I would question would be the thickness of your steps.

They are actually at 21mm which is not much if you are planning on having just naked wooden steps. I usually consider 30mm to be a minimum.

All the best,

Ness

Hi Ness,

I sent it again yesterday, with a message, but it has not appeared in the list above. I will try sending it on it own and with a message.

I assume that these forum attachments do not work like email attachments and are not automatically sent with the message.

Kind regards

Hi Ness,

Thank you for your speedy design.

I have been trying to modify it, by removing the raiils and banisters ( apparently a continuous rail can be provided to fit the stairs on this design) also I have not yet suceeded in making the right hand string on the first step into a cut string.  (see attached).

Height wise, I think the minimum is about 177.5cm over step 3, but I am not sure how or where this is measured in practice.

Kind regards

Steve

Hi Stev,

Had a look a your project and have set you up a template that should work.

I haven’t yet verified the head room with the slanting joist so we might have to adjust a bit the design.

 

stev01v01-1.pngImage Enlarger

 plan-1.pngImage Enlarger

 

Tell me what you think.

Note that StairDesigner as you can see will give a good approximation of the cut strings but the assembly details of the joints with the posts will need to be drawn up by hand .

The goose necked rails and volutes can’t be designed in StairDesigner so these too will have to be added by hand.

All the best,

Ness

Hi Ness,

The files are too big to compress using zip etc, so I have put them on Dropbox here:

https://www.dropbox.com/sh/tzvdeckipcbwa1x/AABpMqGYuuY3YQDtowH4jQKXa?dl=0

I hope you can access them.

Kind regards

Hi Ness,

Sorry about that, I did try to send them. I will try again:)

On sheet 7, I have extra  stock to make the LH cut strings 446mm or even 600mm . I also have extra stock to allow for transitions on the RH from stairs to landing and around the bottom landing.

I have found the reason for the error, in that each of the files exceeds the maximum allowed size to upload, so they were not accepted by your server:(

I will try to compress them and try again.

Kind regards

Steve
