RE: Spark Gap Design

Thanks everyone for your replies. I found them much beneficial.  I am still
unsure of which design I will use but it will be either the linear style or
radial RQ spark gap type.

Thanks again,
Dirk

Dirk,
   The only reason for using copper tube in a larger PVC or similar
insulator pipe is so that you can easily blow air over the gaps. There is
no reason why you can't make a linear arrangement and blow air through those
gaps. I have use this arrangement with a couple of 80mm fans and It worked
as well as any other gap arrangement I have tried.

Hi Dirk, Derek, All,

     The "pipes in a tube " system has, IMO, several other advantages
over linear.

1) Compactness - The PVC tube has a smaller footprint.
2) Less UV in your eyes - The PVC tube is a UV light shield
3) Insulation/Safety - Less HV stuff exposed to dirt, drinks, dropped
tools or hardware, and bits of wire, all of which are attracted to
the small spaces between the tubes according to Murphy's Law ;-)
