It is.  The x-section was about 0.625 inches for the pair of cores  The
big core I am using now is one square inch in x-section.

I haven't yet, but I will publish a diagram when I get it completed -
the write up is not enough to build a duplicate unit or give you a good
starting point.  The schematic is kind of important!  In the meantime,
I'll scribble out a rough working diagram and add that to the updates.
Thanks for reminding me.
