Just a thought. If your design does not allow for 360 degree rotation, then you don't really need a ring commutator. You just need a hollow shaft for the wires to run down. You could even run them outside like on an ordinary oscillator. I also have some ideas on how to reduce friction which is going to be important since it looks as though the head will be off balance toward the blade and cage putting some side loading on the bearings.
