Yeh, a variable speed DC motor would be also ideal to visualize the 
spluttering effect, as you can slowly crank the speed and watch what 
happens very closely. I'm not really looking at grounding my 1/4hp motor, 
but instead, actually acquiring a 1500 synchronous. 
Hmmm, <idea! Bing!> what would it be like putting 2 rotating spark gaps 
in series, mind you working at around 20KVAC -at- 5-10KVA???!!!
Just hope that the contacts are all aligned at the same time for

Well, I don't know about the A.C.T., but in Queensland it's the Dept. of 
Transport and Communications.
