Hi Henry and tnx to you et al for responses.
To answer you question re ASRG type mine is a close look alike for Daniel
Barrett design using a sewing machine motor controlled by a small variac.
http://www.tb3-dot-com/tesla/sparkgaps/arsg_8/arsg_8.html
His low inertia design is hard to beat for simplicicty and cost. Using 5mm
tungsten electrodes. Had a local engineering workshop attach tungsten to the
ends of 5mm brass rod for the rotor. 12 static electrodes on a 10" diameter
circle. Max rpm is 4000 with rotor load down from 9000rpm without load
(variable reluctance pick up with a small piece of mu metal taped to the end
of the rotor )
When the wind drops here in Wellington will give it a go.
