While waiting for my exams to end ( when I can go to the dump, and get 4 
microwave ovens) I'm thinking of spark gaps. I might give a rotary spark 
gap a shot. I don't have access to Fancy-pants codenamed materials like g10 
or anything  ;) , but I was thinking of gluing a large angle grinder 
grinding disk to a washing machine motor, and having lots and lots of bolts 
through it. Would that work? Or am I going to have it explode on me? :/ I 
cut a particle board disk with a jigsaw ( about 16 inch diameter) and 
attached it to my 120 watt grinder- it was so poorly balanced it wouldn't 
spin at more than a few revs per second though, so I thought about giving 
premade disks a try :p (the particle board thing was really stupid in 
retrospect ) :)

Also, on a side note, Dr resonance were you responsible for that great 
tesla coil in the questacon museum in canberra, australia ?
