Glad you survived the Knife, Cliff.

Carbon arc rods will NOT work for tesla work.  The reason a carbon
arc is so quiet and stable is that, on AC, the incandescent carbon
burns during the zero crossing, maintaining a hot, conductive
channel.  The arc never quenches!  Scoping a carbon arc on AC will
show a nice steady sine wave with little to no ignition spike.  A
carbon arc is exactly the opposite of what is wanted for tesla work,
which is, high standoff voltage and quick quenching.

As someone else mentioned earlier, all the simple innovations have
already been tried and either rejected or refined for use at some
point in the past.  Very little if anything to be discovered in the
spark gap area.
