Rotary Spark Gap Progress

I’ve been slowly working on the rotary spark gap (RSG) trying to get it complete by the time the weather starts getting nice. I have the motor enclosure complete and hope to begin working on the actual spark gap section and the shrapnel shield (in case the pure tungsten rod shatters and spits chunks of tungsten everywhere). Below are pictures of the current progress.

Here is a top view of the motor enclosure with the hole at the top for the spark gap portion of the RSG.

Here is the phase shifting capacitor that is connected in parallel to the input power to the motor. This is used to induce a phase shift in the motor with respect to the phase of the voltage at the NST bank. Also note the resistors placed across capacitor to bleed off any residual charge when the RSG is turned off.

Here is the fully enclosed motor for the RSG. At the top is the shaft of the motor where the spinning electrode will be connected to. The outlet on the front of the box is for the phase variable power connection (through the phase delay variac) from the control box.
