Hi all,

I recently attempted to reproduce Gary Lau's sucker gap.  I bought the same 
vacuum motor.  My meter claims 3A for the motor, yet Gary claims about 
10A?!?!  Thats not what im getting at.  My problem is that this gaps stinks! 
  Of course, i could have made it differently, but it doesnt perform nearly 
as well as me RQ gap.  Though, i must say, it makes the coolest noises when 
you turn off the coil, and you hear all kinds of pitched wistling from the 
motor.  It sounds real sci-fi, like a major shut down.  Im running with a 
15/120 PSU.  Im wondering it anyone has used this type of gap, but with air 
blowing outward??  So basically, i need some ideas, or reccomendations, on 
what i should do.  Sould i keep the RQ and put the vac motor on it??  Or 
should i make the single gap, but blow out the arc, rather than suck it up?  
All opinions are wanted.  Thanks,

Steve Ward.
