Give SOTA a call, I hear they're great to deal with
I got an email back from them saying a screw driver is all that is needed depending on motor/housing configuration. That seemed too good to be true so this morning I got more adventurous and removed the bottom plate of the motor/housing. Looks pretty simple wire nuts with a few electrical bits (cap/resistor I think) up to the switch and in turn to the motor. So maybe drop in the motor, fish some wires through and some SOTA specific bits to make it change from 2-phase to 3-phase...though I'm not very electrically inclined I get there is a difference.
They also said in coming weeks a VPI specific options for IEC plates and pully options.
I'm still not clear on what is the difference is between the wall plug and the motor base. If there is a wall wort and small wiring then I guess in the case of an IEC connection something is needed. Mine is just a standard cord passing through the SAMA housing. No removable IEC connection on the outside of the housing.
Long time reader of AGon forums but never posted. So I can't seem to figure out how to post pix. As they say worth a thousand words. I've got a round motor on top which sits under a round decorative plate covering a black, square plate with 4 holes about 2" on center. Wires run to the switch which runs to the "stuff" at the bottom in the top part I mentioned in this post.
