Hi Antonio:
I have been using this configuration (oak supports for the secondary) as
on the
original machine, for over 13 years, dozens of runs of 30 minutes, without
any
issues.
At higher power levels your concern probably comes into play but not with
a 9kV,
60mA neon transformer.

Those wooden supports for the secondary coil are an invitation for a
fire...
