Scott35, your post was not visible to me til after I finished and posted this reply. Just as you say, the line to ground voltages were weird and I ignored them. The thought of adding transformers to step up the incoming to 240 also crossed my mind and was nixed in favor of just getting the right one for the job.
The comments about it being an "open Delta tee " and Tesla's earlier mention of the lack of any "phase angle shift" will have me running the "Google" drill for a few sessions now.
