The lexan material is very strong, however, if enough currents passes
through your RSG electrodes ( a big medium to higher power coil ) it might
soften the pressed in electrodes enough to cause them to come loose and
strike the stationary electrodes or fly off the rotor.

It works fine with 60 mA and perhaps 120 mA coils but not adviseable for
larger systems.

G-10 phenolic ( glass laminate ) is the preferred material for safety.  It
you are giving demos in front of student groups in your college you should
use G-10 for safety.

Best regards,
