Hi Chris,

I think you are on the right track.

However, in my opinion you don’t need to glue steps and risers and you should divide the right stringer into 3 flights.

I would install like this:

Fix the left string to the wall.

  • push step landing and risers 1 and 2 into the left stringer, supporting 2 with a prop
  • assemble the block first post first flight string and second post 
  • push steps and risers 3 & 4 into the left string. With the risers, they should stay in place without support, otherwise use a prop under the last step.
  • engage the bottom of the right string second flight into the step 3 a slightly into 4
  • push steps & riser 5 & 6 into left string and engage step 4, 5 and a little 6 the right string 
  • proceed to the top of the flight and add post
  • do the same for the last flight.

fix the first and last steps of each flight by driving in 2  4mm screws into the steps and strings from the under side.

Hope this is helpful,

All the best,

Ness

Hi Ness,

Currently machining the staircase components. All going well

Thinking ahead to assembly I am keen to get some advice on approach.

We are planning on following procedure:

  1. Fixing the right stinger to the wall as a starting point.
  2. Assembling each step and riser and gluing the right hand side into its position in the right hand stringer. This will involve constructing temporary support to hold the left hand side of the tread/riser in position.
  3. Slotting the left hand stringer into  position with glue in the stringer housings. I can see this alignment problem being tricky. Any suggestions as to how to tackle  the alignment?

 Am I on the right track for assembly or is there an easier way? The weight of the stairs is such that assembly prior to lifting into place is not an option, not to mention the space constraint in moving it in to place.

Another question any suggestion for fixing/holding the treads and risers into position while the glue goes off?  

Thanks

Chris

Hi Chris,

Here are your files.

Yes you can adjust landings with the demo version.

The only things you can’t do are, print, output or display manufacturing data and calculate headroom.

Good luck with the build.

All the best,

Ness

Hi Ness,

Good to go thank you. Happy with the changes as in chris01v02 . Can you please proceed with a set of files.

In terms of  re-setting the landing is this something I could have done in the current demo version or do I need to refer back to you when required? 

Thanks for your assistance. Its a great service!

Regards

Chris

Hi Chris,

One of the limits of this version of StairDesigner is that landings are eliminated when certain aspect of the stair are changed and the stair  recalculated.

This means that you have to re-set the landing each time, a bit annoying I know. We are hoping to change this in our next version.

I’ve reset the landing in the attached file.

I’ve also :

– reduced the last step width to increase the going on the last flight to comply to the stair rule.

– adjusted the step positions to make machining of the recesses easier.

Tell me if this suits you and Stefan will send you the files

All the best,

Ness

Hi Stefan / Ness

I have changed the timber parameters as per my previous post request.

File chris01v01-2 has the new parameters.  

I do not understand why the steps are now showing on a curve and not as previously (chris01v01-1) with the first and second landing square. I need to retain them as square. The only changes I have made between the two files are the stringboard, step and riser thickness and changed the banisters to a square 19*19 section.

Please explain why?

Regards

Chris

Hi Stefan my membership started in December and my first stair design request was in December. Can I please go ahead and treat the rerun as my January stairfile light project. Thanks  Chris

Hi Chris, no problem to get another StairFile Lite. You are entitled to 1/month free of charge with Full membership. If you need Ness to make adjustments to your design before processing, please buy the StairFile Pro service from this page:

https://wooddesigner.org/membe…..discounts/

For more info on each service, and the differences between the two, please see:

All the best, Stefan

Hi Ness,

I trust you had an enjoyable Christmas holiday period and best wishes for 2016.
Currently the handrail at 950mm above nosing is not a problem. The Australian standard requires a minimum of 865mm.

I have sourced some really nice australian hardwood, however the timber requires that I change the finished thicknesses in the design.

Need to finish the steps and stringboards at 35mm and risers at 19mm.

Also want to change the banisters to 19*19mm. The banisters need to be a maximum of 125mm apart to meet Australian standards.

This means re running the model and generating another set files. With my membership can I get a rerun please.

Apologies for these continuous questions and requests as you can see I am a novice in terms of stair building and clearly have lots to learn.

Thanks
Chris
