Charley,
Gerry is right about not supporting the lead screw with the motor. I don't know if it's clear in my photo but my lead screws are supported and aligned with the motor by the opposite end of the lead screw and the lead screw nut. In other words, when I remove the motor coupling, the lead screw is in line with the motor. The thrust portion is taken care of by a thrust bearing arrangement on the lead screw opposite the motor. If the lead screw is not supported separate from the motor, your motor bearings may not last very long.
