Max, If you submerse the whole thing in oil, it shouldn't need to hold up
to even that. And, as only on leg of the secondary will be in close
proximity to the primary, the volatge present will be at best half of the
secondary output.
I doubt it will take that long to wind the secondary, especially if the
bobbin is (I hope) removale from the core/primary assembly. I'm currently
making plans for a similar project--- could you share any
insight/results?
