I'm designing an srsg with an 7" phenolic disc and 4 tungsten points

rotary spark gap can be easily made from a distributor cap and rotor
from a car. Is this possible?
you can try.. but I'm not sure it will work very well. A distributor is
designed more like a rotary switch: it doesn't carry any high voltage
except when the rotor is near one of the electrodes. That is, it
doesn't make and break the HV.
If you search the archives, I'll bet someone has tried it, though.
