J Whyte,

Plan is OK - a few others have done it.  Search the archives for specifics.
The MOTs have magnetic shunts, but they aren;t all that effective to keep
the primary current reasonable.  You may need some extra ballast, which can
be some more MOTs with shorted secondaries, or an arc welder.  Only the 2
MOTs that are floating above ground need the oil bath for insulation, but
all 4 in the oil will help dissapate heat better.  MOTs are skimpy on the
core size usually, and they will draw many amps with full voltage in and no
load.  PFCs help some.  In the meantime, keep looking for a deal on a pig or
PT.
