Here is a front view of the rotary spark gap. The copper pipe and heavy black cable coming from the right side of the spark gap is were the power is transferred to the primary with the aluminum clamp. The 3 heavy black cables on the front of the spark gap is where power is transferred to different parts of the spark gap, This is to have the spark gap break in series at 8 different places every 1/8 of a turn. In other words I have 1 spark gap acting as if it were 8 spark gaps. This causes a very very fast firing and extinguishing of the power for optimum performance. The 8 tungsten contacts on the rotating wheel are connected in pairs. This is by far the best spark gap I have ever built and it probably will be the only one I will ever use from here on out. The difference in how the Tesla Coil acts with this spark gap to all other spark gaps is amazing. It seems more alive, it is easier to tune and I get 10 time more power out with the same power I used to use with other spark gags. If there was 1 improvement that made the most difference in the Tesla Coils performance, it was this spark gap. It can be scaled up or down to fit anyone's needs, the main thing you need is tungsten rods, hooked in series and rotated at the optimal speeds. This one works great between 1.900 - 2,000 rpm's, depending on your Tesla Coil and capacitance speeds will vary,
