This is a perfect case for Flatten Quilt. Divide each piece as you want them cut, place a point along a flat edge, and use the default settings.
You will find there is not a simple "radius" for a solution. You can obviously overlay a radius to see how close it is, but you will likely need DXF files to get the right shape.
Setting up the views is a lot of work. You will be repeating this process quite a few times. Be patient and set up a reliable routing for your entire process. Then get busy.
You might also mark each piece with an identifier. You will loose track with so many similar pieces.

BTW, this is a double start helix both in the same direction. They are both clockwise.
