hello    I am just strarting to make cs  now  and am making it with 4--- 9 v 
batteries i am starting to research  and read that  the particle size might be 
to large  with that method.  can i get some input  and  maybe a good generator 
that would do the right job     thanks

  Dear Glenn, Hi, and welcome!!
  3 batteries are fine. You need about 30 volts and 27 works well. The CS I 
mande that way cured me of Lyme Disease when 6 years of taking antibiotics 
couldn`t.
  Would you like to see the directions I send out to folks who want to make CS??
  Good luck!
