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.
