My WEG 3 phase motor is bolting on without too much difficulty. I had to do a little machining to make it work. I already had this WEG so I thought I would save some money and use it instead of buying something new. There is quite a bit of info on the web about upgrading the G0602 using a 1 HP D80 3 Phase motor that should bolt right up without much work at all. I kept the ability to use the 'back gear' necessary for heavy automated drilling if the need ever arises. I doubt I will really need the low gearing for turning facing operations, if I really needed that much power it would probably rip this thing apart! We will see though.
