HISTORY

 

The first years that I worked as a stairbuilder in training, I noticed that when marking a driven out stairs, some steps were a lot narrower than other steps for those same stairs.
Later on I saw a method that improved that and worked it out in different ways.
I have worked for many years as an independent staircasebuilder with that system, and designed a lot of beautiful forms of stairs. As stairbuilders we know that driving out dictates the shape of the staircase.
Since the rise of computers I also consulted several software companies, but they could not draw our stairs.
We started to write our own program with Leo De Bie, that was still under DOS, we had a lot of fun and it still works.
Later came a realization that this was a mission and that it would be better if many staircasebuilders could use it.
The expulsion methods developed in the course of the last centuries are based on the inner cheeks and are needed because of an error on the course line. We made this no longer necessary if the Stradivarius has been applied, but both methods can still be used together.
Also the drawing of the course line on 1/3 of the wall is actually a hidden solution for what is wrong on the course line. One builds a dangerous stairs this way, because there are too many steps in the turn and since you actually walk in the middle, but there the steps are too narrow.
Over the years we thought to have a problem with the standards, building standards, which in some countries specifically are described by the Division of the course line.
Standards are guidelines and do not always need to be followed, if you can show that under the rules of good workmanship thus is better, there is no problem, it cannot be the intention of standards to do bad work.
If a customer indicates wanting a stair according to the standards, it is not yet possible.
When this system is used by many staircasebuilders then a lot of people will have better, safer and more beautiful stairs. For the stairbuilder it is economically interesting and it will give a little extra professional pride.
Therefore, the price of the patent was deliberately kept low, so that it is accessible to everyone, even if you only build a few stairs per year.
Stradivarius is the key to designing harmonious driven out stairs.
