Hi Burrman,

Many thanks for your detailed work flows very informative still getting my head around the twists and turns I will try Lamina see what results I can pull out off that.

I put this together today thin gauge steel took some work hammer and heat the shape is OK but not flowy and smooth definitely loaded with tension. This is the general direction I envisage it but in a much thicker gauge steel it perhaps maybe just a blacksmith exercise rather than a cad and CNC approach. Perhaps if I build a few more I maybe able to see where I can pass the metal through some rollers in different directions and get the planes flowing smoothly.

Will keep you updated on progress.

Many thanks
Alex.

Hi Alex,
Have you considered a disk shape to make a Möbius strip?
It seems that making a Möbius ring out of a rectangular ribbon shape generates so many tension lines in different directions and requires a lot of force to tame it—but on the other hand, a disk-shaped ribbon produces a much smoother result with far less tension.
Here's a test on paper: I just cut the disk on the red line and then twisted it to form the Möbius shape.
