Re: Spark Gaps (Formerly: Heatsinks?)

Three pieces of copper pipe arranged with their axes in parallel. You can
use end caps or couplings. Easy to adjust (put them in a triangle, and only
one piece needs to be moved to set the two gaps), easy to change to a
triggered gap, easy to make a blown gap (add a muffin fan), lots of surface
area for cooling, and it's cheap.
