RE: Spark Plugs
Terry, thanks for the reply. Feel free to post any part of this if you think
others will benefit.
Here is my plan:
Power dissipation: Force fit or sandwich using nuts, each plug body in a
large, big finned (power transistor type) heat sink. These are typically 3x4
inches.
Align all plugs for most compact design in an enclosure. A spaced column for
example.
Use 1 or more high speed muffin fans to blast air over all surfaces and the
tips of each plug.
Use appropriate heavy duty wire to series connect.
Shield the enclosure using close mesh and ground that to the RF ground to
reduce RFI.
The benefit I see is an easily controlled gapping, convenience in mounting,
convenience in servicing.
And what is a "small coil" these days? Mine is designed for a 15KV/60mA NST
supply into a 6x24 secondary. Does that qualify? [no pigs allowed at my home
:)].
Thanks for your assistance.
Ted

Hi Ted,
Power dissipation. A car plug may overheat and fail on a resonably
powered Tesla coil and they have a fairly long RF path that adds to RFI.
However, on a small coil they have been used for decades with good results.
Cheers,
Terry
