Here is a method I developed for creating a helical curve along a path. It has many applications including modeling a rope, cable, twisted wires, and other organic helical shapes. It has advantages over using the built in helix primitive in that you can control the path of the helix precisely.

For the bars that go between the helix you can use an animation snapshot. I have a tutorial someplace on the site for creating a chain and fence posts that demonstrates that workflow. The idea is you sweep a bar along the same path as the one used for the helix and key it's rotation at each cv along the path.

I can just fill in one gap with the lines and then duplicate them in the same shape for each gap, as they're all same size. Once I'll combine them into a single mesh, I just put in a bend deformer and it will be perfect.
