David,

It would be interesting to do a test by installing some electrodes
that are turned down to 1/4" dia or so near the ends to reduce the
mechanical dwell time, and see if this lets you go to a lower bps
without the power arcing.  Another alternative might be to test
some electrodes that are rounded to hemispheres at the ends
(but flat at the center of the hemispheres) and see if this stops
the power arcing at the low bps.  These test electrodes could
be made from steel or copper to keep the cost down and
simplify the test.
