Aligning point cplanes radially

How do I align the control planes at divide points on a circle to have the curves at those points normal to the circle? in the case of my definition those curves are circles. At this point i am only attempting to make a donut and then play with it. I can sweep just one curve but want to divide it next - or take a bite out of it. This is a learning exercise for me.

The solo components in the definition have been tried without success.

Thanks for the help

Perp Frame or Perp Frames components. Instead of divide curve.

Here is my definition
