Re: Tungsten static gap



Original poster: dhmccauley-at-spacecatlighting-dot-com 


One observation is that most people who are building static gaps are
typically beginners and first-time tesla coilers.  The beginners and
first-time tesla coilers usually use
what they have easily available at their disposal and also are running at
low power where tungsten really isn't necessary.

On the otherhand, the more seasoned tesla coiler is willing to put in the
extra time, effort, and money and build things very carefully especially
with higher powered systems.

But for most static gaps, copper pipe is adequate enough.  Tungsten isn't
the easiest material to get (especially in larger diameters) and is
prohibitly expensive for the average
tesla coiler.  I recently purchased a bunch of 1 inch long, 0.25" diameter
pure tungsten rods for my ARSG gap and paid $15.00 each for them!!!
