leadscrew was ground finished for accuracy and its bronze engagement clasp nuts adjustable for backlash the power feeds were taken to the apron by a separate keyed shaft working though a torque-limiting coupling that also, very usefully, permitted work to be turned against stops. I have checked out the other links you posted but i am sorry to say that i am unable to help. It is not clear (to me) if you are having issues with the cross feed, longitudinal feed, or both. The Mondiale Celtic 14 lathe you linked to is a fine looking machine.
