Well,  I'm still trying to think  'cheap' here.....anyone ever try 
using a hard lead pencil(not a soft no. 2)  for the needle?   I don't 
know that there would be less friction that a sewing needle, but 
perhaps the graphite would not create a lot of friction.  It would 
also be fairly conductive.   Just a wild thought here.

  a good, metal, 'point in cup' bearing, is quite good, better than
  ball bearings fro starting friction, and easy 8)>> to had craft.
  Built a spinner once that way for the relatively low
  voltage of 15kvdc...
