The feed shaft drives a worm gear, which resides in a cradle on the rear of the saddle. This drives the longitudinal gear, which a clutch used to engage the cross slide. Here are the pictures form the other lathe:
Now - what I have to work with:
What these don't show is that I do have the large gear that engages the worm (and the feedshaft itself)
The gear needs to be repaired, as several teeth are broken or chipped. I then need to work out how to determine the diameter and pitch of the worm. Of course, then I have to make up a clutch assemble to power the cross slide.
