My 3" diam NST coil has a static gap with 3 pieces of 1" copper pipe.
Doesn't work very well after the first few seconds without a fan.  Added a
110V 4" muffin fan  and it works like a champ. (It's very quiet, not that it
makes much difference with a spark gap making all the noise, but it's also
not very high flow, so it doesn't take much air to make a difference.)

Clean the inside of the tube real well first (so there isn't any residual
carbon tracking).. then..
Cut some disks of plastic (anything will probably work) the same diameter as
the tube ID and silicone them in a few inches from each end (like, as far as
your fingers can reach)... precision isn't important, nor is appearance,
just make sure you goop the silicone in there so there isn't any gap.
