Paralleling Variacs

["Tesla list" <tesla@xxxxxxxxxx>]

I am building my power control center for my big coil. I am 
paralleling three Staco variacs, rated at 30A, 520V each. I built 2 
paralleling chokes. Do I attach the wipers of 2 of the variacs to the 
outside terminals of one choke (3rd wire is a centertap of this 
coil), this now being the output of this pair? Then attach this 
tapped output to one of the outside legs of choke #2, and the other 
outside leg to the wiper of the 3rd variac? then the centertap of 
choke 2 is the main output of the 3 vriacs. Long and a little 
confusing, I know! Hope this is clear, and I'm ok with this. In 
particular Bart ( or Bert?) and Scott D. have discussed this in 
detail some years back on this list, but I can't seem to find wiring 
diagrams for 3 variacs. As always I look foreward to your replies.
