sheet metal torus with flat pattern

[simon]

is it possible to create a spiral torus from segments /petals/

I can do the attached shape but I want a spiral form

Do you have an image of an existing similar design from the real world?

Yeh, We made the attached steel tool with cones and our existing 2d package. A bit of a challenge because it had to fit into the fabrication below, I'm wondering if its possible to create a flat patter for this complex shape?

(It doesn’t matter that it is not correct - I just need some dimensions.)

How many sheets (petals)?

[simon]

We are working on 72 petals but that seems to take a lot of computing as I get more and more petals, so as Im trying to work it out im using fewer petals.
