Hi from a newbie in Wiltshire

Hi Vince nice to see another local, as Irving says go wit the VFD. I'm in the middle of wiring up my 3HP 3 phase lathe at the moment myself with one. Don't be afraid to change the wiring either as if you sell the lathe later will probably go to another home user and they will want 240v. Your existing motor will probably be able to be wired to Delta as well.

Vice i have a VFD on my lathe but if i had to do it again i would go for an ac servo motor

You will still have speed control but full power from 0 RPM to full speed i know that may be slightly untrue technically

You would also have the ability to do rigid tapping as and when software allows it

If you want high torque at low rpm then best to leave it in Wye...or have a switch to change between that and delta if you're really keen.
