Chip,

Thanks for posting the picture of my control board (pict ES1).  I enjoyed
your pictures.  What size is your toroid?  What is is made out of?  It looks
similar to mine but is much larger in height.  I think mine are 5 or 6 inches
thick, made from pvc drain pipe.  Yours looks to be about 10 ".

I also enjoyed Mark Bartons pictures.  What a project.  I sure would like to
see it run.

[ The toroid is made of 7" Al drier duct, soldered to two Al pie pans that
  are 9" in diameter.  In cross section: O>--<O.  I think mine looks much 
  larger because it's only about 22" in diameter (7 + 9 + 7 -~1), so
  the aspect ratio is .33 or 3, depending if it's w/h or h/w :-)
