Very nice work so far - the machine looks nice and solid and appears to be in great condition. Those servos are enormous
I didn't see the knee lift crank or servo - were those mounted on the opposite side of the knee to the Y axis motor and screw?
This will surely be a very capable machine soon, 40 taper and a 6Kw spindle suggests you'll make short work of some pretty big jobs. I'm looking forward to seeing it come together!
