Balancing 3 phase con.

Years ago, I think it was Fitch, posted a "system" for
selecting the caps to balance the outputs of a rotary
converter. Does any one have that squirled away ?
A friend is geting ready to build one for a Bridgeport
and I have looked at the stuff on Metal web news but
don't see the order to adjust values to obtain optimum
match. Is it in the drop box? Without a good title I'd
never find it if it is.
Thanks for any ideas.
