Hi Jim,
  You could use zinc but it's not a good idea. The zinc will smoke off as
it's burnt away by the high temperatures of the gap and underneath the EMT
is just steel anyways. Not to mention how corrosive the ozone is to the
metal. The ozone will make things rust really mast! Better stick with non
ferrous metals only. Brass is easy to come by and doesn't cost much at all
and copper isn't much more either, AND they are both a better conductor.

Hi Folks:
I do appreciate the great assistance with my tesla coil that I have
received from you.
Can I get your opinion on a few things?

1) Can I use 1" EMT (Electrical Metallic Tubing) for my spark gap
instead of 1" copper pipe?

2) Can I use zinc coated bolts and nuts for my secondary instead of
brass bolts and nuts? Zinc is what most bolts, nuts & washers are coated
with.

3) What does the term quenching refer to when speaking about spark gaps?

Thanks for the informative help!
Jim
