Just a comment on the above paragraph as I'm converting this to a PDF...

Medium sandpaper may be a bit rough for this. What's recommended is either fine sandpaper or crocus cloth which won't leave as deep of groves.

Also the area indicated "contacts on the main coil" are not actually contacts. They are stacked plates though which the wires are wound and multiply the field generated by current flowing though the wire. in the 2nd photo you can see the individual plates. That said, clean is good
