Hi Malcolm,

I measured the pri and sec in series in both aiding and bucking
arrangements,
and then calculated the mutual inductance, and then the k value, using
the
appropriate formulas.   Most of the k values I posted were approx.
because, I
didn't remeasure the k after each successful k "position" of the sec,
but
instead interpolated from previously made k measurements.

BTW,  I observed my quenching using a better quality scope, and I can
now see
that I am actually quenching on the second notch, not the first.  This
explains the anomalously short (and linear) "ringdown" (actually the
excursion towards the notch) I was seeing, the (low amplitude) true
ringdown
had been "lost in the noise" in the old scope.   Sorry about the
confusion.

Regards, 

John Freau
