This is a picture of my newly modified spark gap. The electrodes used to be 3 inches long,
Here you may see that the gaps are easily adjusted and may be move around for a bigger gap size.
The electrodes are made from a copper pipe that was cut in to 3" segments and are 1.125" in diameter, email me at moonol05@email.pct.edu
now they are 2 inces long. Cooling and quenching is provided by a 3 inch fan. The air flows
between the 3 gaps out through the back.
The gap is set at 0.192" each gap is 0.064". I have milled groves for the airflow
between the electrodes and for the bolts to move the gaps.
but following some advice from the Tesla Mailing list I cut them down to 2.125". They are held
in place by aluminum C Channel, it is 0.875" wide, 2" long and 0.5" tall, this also helps with
cooling the gaps. I have used the previous version of this spark gap and worked very
well. This is also a great deal quieter than previous gaps that were used before
because this one is enclosed in plastic.
if you have any question or any tips.
