Re: Tesla to buy - 1 week - New York City
Original poster: "S Gaeta by way of Terry Fritz <teslalist-at-qwest-dot-net>" <sgtporky-at-prodigy-dot-net>
Hi Dawn,
I really wish I could help you out since I am on Long Island, but it's too
short of notice for me to get things together, and then do a test run with
you.
I would however, like to offer a few suggestions. It's really not that easy
to water proof a Tesla Coil, so it would be a good idea to keep the coil
outside, but very close to the enclosure. You can then drill a small hole in
the enclosure at the torroid, and use a metal rod connected to the torroid
and passing through the enclosure wall to bring the high volage into the
enclosure. You will probably need a pvc pipe around this lead in, where it
enters the enclosure to keep the high voltage from tracking along the inner,
wet plexiglass wall.
And please, be very very careful! High voltage is nasty stuff in dry
environments, and can do some unexpected things if you are only used to
working with low voltage stuff. In wet evironments things can really get
wicked nasty and dangerous. Also, tesla coil discharges are radio frequency
high voltage. Even the best insulators will pass these frequencies if things
get too close together (ie: innocent looking objects suddenly become
capacitors!) It would be a good idea if whoever provides the coil can be
with you during the testing, and implementation phase of this project. The
person who built the coil (hopefully) knows what to expect, and can show you
the tricks as things move along. There will be problems that will come up
that will need to be engineered out. Having a high voltage expert nearby
will help tremendously!
Good luck, and Godspeed! I would really love to see you carry this out
successfully, and safely, and then post your results to this list. I love
oddball experiments with high voltage. I did a small scale experiment with
water and high voltage once as a joke, and was suprised at the neat effects,
and photos I got out of it!
Sue
