Thanks Rod,
I'm thinking I may go for a 3Kw (4hp)

as I'd like to make some money with it. Do you think this mill build could handle that much power (rigid enough) as I may go a similar rout with my mill. I know I would need bigger steppers or servos? I am also considering a much bigger mill but could do this convention for less money.
I hope you don't mind all my questions,

John
