Thanks for the input George but I dont really need to sort a motor,

I already have plenty of 3 phase motors and a VFD, This also isnt a budget build. What I'm trying to work out is far to go without over doing it on the spindle and bearing side.

Anyway I think I have decided on the layout and bearing configuration so I will post some drawings soon.

Then I will need some advice on the best way to actually make it. turning between centres and line boring etc.
