Hi Mike, I have experimented with aluminum in both rotary and static gap 
situations. 
Unfortunatly AL has a tendancy to oxidize badly in these conditions,therfore 
creating an unstable or eratic gap fireing. As to the question reguarding 
electrode shape ,I've 
seen both the hemispherical and flat faced gaps and both work well.The thing 
to note 
in these situations is that there are no sharp edges, this causes both 
ecsessive heating and wear in either case thus causing unstable fireing.I'm 
currently waiting to compete my "New SRSG" so I can give more results 
reguarding the Q of the gap and primary circuit ,I'll post my findings when ( 
if ) I get the motor :)
