Picked up a South Bend 9c last month. It seems to need a bit of work, but nothing out of the realm of possibility. Figured I'd start a thread on it since I'll be doing a full restore, and wanted some documentation on it as I start working on it.
The Good:
- Change gears and chucks present and in good condition. Had to buy an 80t idler gear for the gear change set, but aside from that I seem to have the full compliment of standard gears.
- Headstock spindle seems to be tight and within tolerances.
-Ways are slightly worn, but not too badly.
- No rust anywhere that I could find.
- Cheap quick change tool post was included.
The Not So Good:
- Apron, compound and cross feed need some work, likely needing new crossfeed and compound screws and nuts. Backlash is really bad, 3/4 turn of the knob or so. (seriously considering an entire South Bend "B" apron and compound at this point)
- Needs a new rack gear, or I need to repair the teeth on existing.
- Switched out the motor and switch since it had a smaller motor and single direction switch.
-Lead screw is slightly worn, but not overly so. the shoulder on the stop collar seems to be worn more than the threads or the half nuts, so I may be able to take the back lash up with a shim in the right place, or refacing on of the bearing surfaces.
-Tailstock has an issue. A lot of play, and it won't lock down on the quill. May need a new quill, or there may be something else wrong.
