2d drawings are helpful right?

Sure, that greats opportunities to realize this project


Why is the central hole square? Wouldn’t the orientation of the square hole have to change with each step, requiring dozens of unique steps to cut out? Whereas a round central shaft would enable you to make only the 4 basic outlines of steps because each could be rotated to any position on the supporting shaft?

This is awesome as hell!

In the center there is a supporting brick column, it has a square cross section. The customer had a desire to make steps around the square to strengthen the staircase structure.

Thank you👍

Great work :star_struck::star_struck:

Very nice @Antey85 :clap:
Check out ‘Grand Designs’ on Channel 4 (UK). There was an architect that did something very similar to this - end result looked really good.
I’d also add in a part number to the CNC - thats one big puzzle! :laughing:
