Being a Scot or a Pict, not clear which, he just needs to make sure he applies the woad in the right places!!!

...that I didn't let the blue smoke out and the jury-rigged VFD & Motor worked fine. 
However, it's not a working machine because the final drive belt (the T-link one) just slips as soon as any load is placed on the system. As everything is driven off the spindle through gears any application of traverse of cross-feed stops the spindle, but the motor and all of the belts keep on trucking.

Our visa stamped passports are now ready for collection!
Wow, that is a record! Just less than 3 working days.
Wish the rest of it worked so well!

Don't argue with idiots because they are experts at dragging you down to their level and beat you.
I can honestly say that I did not understand one word/figure of that....that I may be in trouble wit the lathe motor current requirements.
IF you change a 4XX Volt 3-phase motor from Y to Delta, yes the current goes way up.
So a 480v motor went like this in t'interweb experts calcs:
Wow! that's a huge increase.
Volts Root3 Winding V Ohms Amps "WYE" Delta
But…
I am going from 400v Y to 230v Delta, so it looks like this:
No none of these figures are measured, just calculated on standard formulas.
Volts Root3 Winding V Ohms Amps "WYE" Delta
So we are going up to 20A maybe. I wonder if my 16A breaker will go pop?
Maybe I will need to alter my Garage “Spur” to 30A.
@My Old Landy ...what did yours come out at Brian, and what size breaker is on your lathe circuit may I ask?
Neither did II can honestly say that I did not understand one word/figure of that.
Night all!

That looks good. Electronic speed control, plus forward and reverse all working well. A lot better than some of my experiments with second hand electric motors where they just buzz but don't do anything, or go round backwards very slowly. Maybe just renewing the relevant belt would help. They get a bit crisp and highly polished as they age in my experience. A new one will have contact faces that are all soft and rubbery. Maybe there's room to install a home made jockey wheel with a spring somewhere in there?
