Earl,

I have used 4 MOT secondaries in series for a DC resonant charging reactor.
Of course, they need to be mounted on insulators and spaced apart, but they
don't need to be submerged in oil.  The MOTs work fine with no airgap as
long as you stay above the minimum break rate to avoid trailing arcs in your
RSG.

There is another way to run a DC resonant charging coil that avoids the need
for the large iron core reactor altogether.  Instead, it just uses a small,
easily built air core reactor.  It does require an extra set of gaps on your
rotary spark gap.  The power supply resonant charges the MMC through one set
of gaps, then discharges the MMC into the secondary with the other set of
gaps.  This works wonderfully well, allowing break rates as low as you want
with no risk of destructive trailing arcs, and effectively disconnects the
power supply during the main bang.

Contact me off list if you want more details on the alternate method.
