Answers to plans.
3/4: Don't bother, hit and miss whether you will get run out from just a thread and no register.
Instead get a standard MT3 ER32 collet chuck and machine a groove in it with carbide tooling and fit a circlip to hold the washer and the M62 nut.
BTW I have a short threaded test piece with the Arboga thread on it, OK if you want to borrow it or if you are dead stuck I can make you a threaded sleeve.
5:You could always buy a 440 v 3 phase VFD feed it 440 v single phase from a yellow brick wired backwards and the earth centre tapping removed and use this as 440 v in but de-rated. You can pick 440v input vfd's quite cheapJohn S -
