Progess is being made.  I kind of dead bugged a LM317T onto the side of the shield.  It creates a regulated 13V rail that will power all of the drivers.  I also switched out all of the drivers for new chips that I had just got from digikey.  At first 4 of the 6 commutation stages were working, but then I discovered one of the resistors was not soldered to the board and that solved the issue.    Currently I am cycling through the 6 commutation stages with 100 millisecond delay between each stage.  Here is a short video.
