Charles,
The best way o break in a new cap of home construction is to actually run
it in Tesla coil service! The big thing is to not even slightly stress
it! close the gaps up to near extinction and run the system for a number
of minutes. Bubbles and such might be seen surfacing in the oil. This
is out gassing the trapped air. As the air bubbles diminish, open the
gaps and fire at increasing stress levels for shorter periods of time
until virtually no bubbles are seen at or near the actual operating area
you plan to use. This may take a week of work for a few minutes per
evening.
I don't think your 100Kv units will ned this though.
