Help with elliptical helix staircase (PHOTOS)

I am trying to fabricated an elliptical helix staircase with only a beam in the middle by modeling the beam in solidworks and than using the flatten surface tool to get the geometry of the faces and cutting them with my plasma CNC. So when I weld those cutted faces together and make sure to keep them perpendicular to each other will it construct the desired elliptical helix here is the stair case https://preview.redd.it/i8tktnmtddd41.jpg?width=800&format=pjpg&auto=webp&s=b05ac2e333c20fa45f1f5e444fa12dcc20b4a7f7 ​ https://preview.redd.it/wz51ie23fdd41.jpg?width=1920&format=pjpg&auto=webp&s=f22f7682df661c3ab6d3ef686be11e57c61ba896 https://preview.redd.it/v6gf98l4fdd41.jpg?width=1920&format=pjpg&auto=webp&s=8bfcf8a77e259101c3e932c740333dea61bcd837 and here are the side and upper faces i got ​ side face https://preview.redd.it/jqnrei0dfdd41.jpg?width=890&format=pjpg&auto=webp&s=2cf8f3586c143cc90cd1fe4e4248e14f06177b73 upper face ​ https://preview.redd.it/2nd8wo2hfdd41.jpg?width=933&format=pjpg&auto=webp&s=a3bb5f6f07099f03e25f3f2351cc17c9dcd85cd5 submitted by /u/friland96 [link] [comments]
