RE: small 4KV transformer, anyone?

That is gonna pack quite a punch...

Under ideal conditions, if I remember right, it will
be over 20J in the discharge, and 10 and over is in
the dangerous zone.  The little 18" one I have can
ideally get to around 5J.

As they say the only stupid question is the one unasked, but I was
wondering what is the largest VDG that could be built and still be
considered safe (tho perhaps uncomfortable) to be hit by? I came
across 400kV 10uA ones when I was in high school. Is that the "safe"
limit (considerig alot of goofball kids around it)? Was thinking of
using 1 of those 30" steel ball lawn ornaments I have lying around to
make one whenever I can find some suitable 4-6" pullies (aluminum and
teflon hard to find), just don't wanna kill myself when I go to do
the hair-standing stunt.
