Here is a snapshot of the 18/1 that Bill W. is currently building. He has done a thorough blueprint on the internals and added a mini-turbocharger (with charging chamber), and external rotary oil pump among other mods. So far it all seems to be working as intended but no technical data available as of yet.
Bill is also building his own PMG generator heads to provide a load for his new baby... here is one prototype that is now operational:
and the back side showing bearing mount and rotor.
Pretty impressive fabrication work - especially when viewed up close! WOW!
I will try and keep you posted on progress with this project.
