  Thanks for posting this, Jarmo-
  
  If you knocked the core leaves out one by one, I admire your tenacity--I used the brute force (hacksaw) method! Last winter, I made an electromagnetic pickup from one of the "half-bobbins" you show above, cutting through the metal core pieces and the coil farthest from the high voltage (plug) side, leaving the smaller diameter wire on the other "half bobbin." I then put a couple of RadioShack magnets in the middle, and mounted it in a plastic single gang electrical box. It was an okay single pole pickup, but the output was pretty low, because the wire coil was not very close to the magnet on my version.
  
  Talking with Cooper-Moore later, he indicated that he unwound the wire from the plastic "bobbin" and rewound it around some RadioShack magnets he had taped together for a much better pickup.
  
  Mortimer, do you suggest dropping a bar magnet inside the bobbin from corner to corner? This might work, but my thought is that the output will not be as high as if the wire was pretty tight up against the magnet all around. Or if you had a huge bar magnet that would just fit the hole in the bobbin.
  
  Best regards, Willie

  Wire one of those up to a jack, stick one of those bars inside from corner to corner, hold it over a guitars strings, plug it in and see what you get.
