Hey Blue,

     I wanted to ask about how you keep the two magnet rotors aligned. I think my design follows yours somewhat in that I have a center shaft as opposed to the five bolts like we see on the wheel hub design. For that reason I only have magnets on one steel disc so that alignment didn't matter. The second disc was only steel no magnets. But it looks like on your dual rotor you only have one nut holding the rotors on the center shaft and I'm wondering how the alignment went. I'm lousy at explaining these things, did that make sense?

 hi andy . what you asked i found very interesting in practice .
   when i was making a shaft to try out two rotors i made a key way.
  as bothe rotors also had a key way.

   fitting this together i had to make sure the key ways were aligned .
  so i could get the key in line.
  but then i saw every time i put the second rotor on with the jacking screws .
  it was always in the right place.
   can you beleave the rotors line themselves up.

  but i do have marks on each rotor so i can just move it a fraction
  for 100% alignment.
   with the small rotors i have .only 8 magnets each . it is possible to twist
   them a small bit. maybe a 1/4" . so i just check out the marks i made.
   (if the other one is locked in place.)

  first time i have used jacking screws.  thay are a must.

  dont ever be tempted not to use jacking screws.
   as the one your trying to put on will pull the other of the shaft

    in short the north pulls the south and vice versa.
    two rotors are twice as much fun and twice as much power.
    double the amount of fun you get andy.
   make a second rotor.
its a ill wind that dos no good
