No need to feel jealous! These Hardinges have to be kept going they're classy!
What type of Spindle drive/motor does your GE based machine have? AC or DC? I have real issues with those old DC drives, hence the reason mine got removed. So far I'm more than happy with the 3kW AC setup I now have. Siemens Micromaster 440 drive and matching braking resistor and Siemens 4 pole Iron Framed motor. The motor after milling the round flange square like the original was a drop in replacement. I think the original motor was either 3.5 or 4 kW.
I think actually when I think back over all the purchases that spindle setup was the most costly. 2nd was all the replacement 5 port valves, and then the servo motors and drives. All the rest added up to quite a bit but I'm happy now!
