The spindle servo is MUCH larger than your x,y, and z axis servos. Maybe we misunderstand each other here, to me a spindle servo turns the spindle. Are you thinking of the Z axis servo?
Resolvers are totally obsolete, don't know of anything that fools with them anymore. Not that big a job to replace it with an encoder.
You should be able to keep the servo motors themselves and the power supplies for your new control.
if you ever decide to toss that tool changer, let me know. Or, why don't you just toss the whole machine and give it to me? <GRIN>
