Dear Jay,
Thank you for this. This all sounds good to me. 
All the best, Roy

Drawings for final machining and coils are still in preparation.  I will likely write up the next PR asking for costs to fabricate two E-cores (one magnet) or four.  I'm leaning to four if the incremental cost isn't too high because Tommy Hiatt told me that he'd had problems with small voids in the material.  I'd like to be sure that we end up with at least two good E-cores without contract changes.
