#24 or # 26 AWG will work good for this coil design with 4.5:1 height/dia
ratio.  Use 200 degree C wire if possible for longest possible lifespan.  A
PT with 14.4 kV Erms set for 265 mA drive and a .06 MFD cap.  Asynchro RSG
12 electrodes on a 12 inch G-10 disk running at 1725 RPM.  6-7 ft long
sparks.
