Hi Freddy,

Attached your documents. Be aware that if I have to manufacture the stair then use risers with a 11.5mm thickness as this is what I use for risers. This is a veneer riser on mpx base.

I will have your quote send soon for this manufacturing

includes 

making of all the parts and cnc processing

sanding the parts

not preassembled nor finished 

regards

Michel

Hi Michel,

That will then be the next project.
Can I get the work files and the dxf files from the current project?
In the first place, I want to carefully measure and check everything again.
I hope everything is already a bit more accurate and fits.

Greetings and a nice end of year party

Hi Freddy,

This is not possible in stairdesigner. The only way to make this is creating an extra stair with fitting dimensions to add in the build.

You can put them together in a cad program to see the results but you can not make it as one stair in stairdesigner. Also in most of the stairprograms even the expensive ones this is not always possible. 

regards

Michel

Hi Freddy,

Just to be clear. When using a traditional setup with a visible stringer means that the shape of the concrete stair needs to be cut out below the wooden step and behing the risers. See picture. So a penetration of 42mm which is the complete width of the stringer will just weaken the structure. 15mm is enough. You need the width of the stringer to attach the steps with screws so it needs to be strong.

About the 97mm.  On your stair the stringers are different. If you give them the same width and type sd7 will make them one stringer. You can then set the height you wish in this case 70mm . I suppose most of below the landing will have to be cut due to the concrete. I also changed some other parameters and stringers to make it fit better. I added a small video so please check

Hi Michel,

I had done the high offset above the noses to have enough space for lighting (spots) to be built.

I added the 97mm offset to the stinger because the stinger did not match the riser under the landing.

The left stinger (outside) I had set to 42 mm penetration because the concrete staircase is anchored in the wall so that the noses and risers of the stairs were under the outer (left) stinger. The part of the stinger next to the noses and under the noses should leave. Or is there another way of implementation.

regards,

Freddy

Hi Michel,

When i download Stairdesigner on wooddesigner.org i get always 7.05 and not 7.05A. Is there some place to get the right version?

regards,

Freddy

Hi Freddy,

Dutch is not allowed on the forum as all members must be able to read the posts so please switch back to English 😉

You need to download the most recent version 7.05A to be able to open the file

Dag Michel,

Nederlands toch net iets makkelijker om te communiceren. Bedank voor je advies.

Ik heb tot nu toe “engels” gebruikt, ik wist niet dat nederlands toegelaten was.

Ik heb je bestand gedownload maar kan het niet openen met de demo versie 7.05

Melding : “The file was created with a more recent software version”.

 

Dank en vriendelijke groeten,

Freddy

Hi Freddy,

Not all was done correctly. I changed it so check 

I removed the 650 mm overpass as this you have to do with a seperate piece to connect with the door list. It would make it too difficult to place the stair on his place 

You gave me no answer on this one ? I also change this  to what I think looks better . Check the stair I send you 

You have a very high offset above the step nosings . Is that needed or only on the top of the landing ? offset 70mm and the stringer on the landing is 97 mm offset ?

For a first stair it will be challenging as you want to cover an existing concrete stair so pay attention to have an accurate measuring of the concrete stair and put it in a cad program. When you have your documents and files you can import your stair to put it on top of it and check if everything fits which I doubt it will the first time. If you get your files this month you will be allowed to get a corrected set next month but You can only get 1 set of files for free per month. 

Also height check is important and check if the outside stringers will cover far enough downwards to cover the concrete stair until the finish part of the wall.

Also depending on the situation which I do not know you will have to cut out the stringers tha will remain on top of the concrete stair. This cutout can be drawn in a cad program too to adjust your stringers. 

I see you speak dutch normaly and you are from Belgium. Same for me 🙂

Good Luck 😉

regards

Michel

Hi Michel,

Thanks for the advies on the technical side of the stair, I greatly appreciate your advice.

  • Do you have earlier experiences with stairs ? No, This is my first one
  • 30mm penetration is too much . Reduce this to 15mm                  I think, it is fixed
  • risers needs to penetrate the step above around 10mm               I think, it is fixed
  • the riser needs to be priotised so that it comes behind the steps for screw fixation           I think, it is fixed
  • also the penetration of the stringers in the newels please set to 15mm and if you use this option of              penetration I advise you to use a upper and lower recess of around 25mm to fit the stringers in the newels.            I think, it is fixed
  • the newel on the stair start ( post 3) should notch in the first step and riser     I think, it is fixed 
  • What is the reason of having 650mm beyond the last step on top of the stair ? Then the left stringer connects nicely to the door list
  • Do you need the 140 mm  length beyond the first step on the left stringer ?  Then the left stringer connects nicely to the door list
  • Do you have an exit on the left of the landing ? Yes
  • Is that correct on width an measurements ?  Needs  to checked
  • You have no banisters in the railings . Are you going to use something else ? Yes
  • step 5 is not set in the most elegant setup on the newel. Should be set inside the newel or more outside of it depending on the situation you are in but that small part coming out is not looking very well I think, it is fixed
  • small problem on step 7 that is cornering the newel . This should be avoided if possible  How can i do this?
  • riser of step 8 is not covered by the stringer. If not possible to notch it in the newel then the stringer needs to be adapted . The latest version of SD7- 7.05 has this possibility.    I think, it is fixed
  • steps must also penetrate the newels by 15mm   I think, it is fixed

At this time i just need the plans for a price calculation, wood and fabrication. I make the final plans later when i have a target price. I hope this is possible?

Hi Freddy,

Do you have earlier experiences with stairs ?

I see some issues on the technical side of the stair . To cover a concrete existing stair it needs to be measured well and fit on the concrete stair. I do this in a cad program where I draw the measured concrete stair top view to see if I have the needed clearances to cover the side and the steps. Also a height check needs to be done to see if the concrete is not going to bump into the steps. 

First of all some technical issues 

30mm penetration is too much . Reduce this to 15mm

risers needs to penetrate the step above around 10mm

the riser needs to be priotised so that it comes behind the steps for screw fixation

also the penetration of the stringers in the newels please set to 15mm and if you use this option of penetration I advise you to use a upper and lower recess of around 25mm to fit the stringers in the newels.

the newel on the stair start ( post 3) should notch in the first step and riser 

Do you need the 140 mm  length beyond the first step on the left stringer ??

What is the reason of having 650mm beyond the last step on top of the stair ?

Do you have an exit on the left of the landing ? Is that correct on width an measurements ?

You have a very high offset above the step nosings . Is that needed or only on the top of the landing ? offset 70mm and the stringer on the landing is 97 mm offset ?

You have no banisters in the railings . Are you going to use something else ?

I would not penetrate the handrails in the newels but set it flush so that you can fix it with screws through the newels

step 5 is not set in the most elegant setup on the newel. Should be set inside the newel or more outside of it depending on the situation you are in but that small part coming out is not looking very well

small problem on step 7 that is cornering the newel . This should be avoided if possible

riser of step 8 is not covered by the stringer. If not possible to notch it in the ewel then the stringer needs to be adapted . The latest version of SD7   7.05 has this possibility. 

steps must also penetrate the newels by 15mm

regards

Michel

Hello,

Thanks for the fast reaction, I hope that now I uploaded the file correctly.

Yes Michel thats exactly what I want to do.

the outside stringboard just need to cover the steps, and i want to place some led’s in to the stringboard or steps.
I think this is not possible i Stairdesigner or am i wrong?

Pleasant end of year celebrations and greetings

Freddy

Hi Freddy,

I don’t see your file attached.

Just to inform, the answer will be possibly longer than usual as most of us are on holiday.

Thanks for your understanding.

I’ have a premium account here and I want the dxf-files and the manufacturing documents if possible.
It is my first project with stairdesigner, I hope it is a bit OK.wink

Thanks,
