Hi Chip,

This does not look right to me.  The flux needs to cancel from the three
windings and this is not possible on one core.

I used two 225VA transformer cores to parallel three variacs.

One has two windings with 16 turns on each and these couple two of the
variacs together to give me 30A output.

The second core has two windings on it.  One has 8 turns and the other 16
turns.  The 16 turns goes to the third variac and the 8 turns goes to the
output from the first balancing transformer from the first two variacs.
Total current is 45A.  The flux cancels in both cores.

Cheers,

Paul.
