Hi machinist folk
I am finally getting into cleaning up and discovering the condition of my (now two) South Bend lathes. One is a 9C, picked up for a crazy price ($147 equivalent) a couple of years back, and more recently, a 9A for a bit over $500, because I wanted the QC gearbox and power cross-feed apron.
Also, to some extent, I need each to help fix the other.
I this company, I guess we are used to seeing pictures that make us feel, well.. "not-so-good", but I am thinking I should be looking for a repacement quill for the 9A. If there are some that are available because they have been "parted out", because of some event that made the whole machine unviable, like it "got dropped" or something, then that is OK, but a good many "parted out" bits are now actually the just leftovers from the machine having donated it's best to another.
The $147 South Bend 9C is the "better" one. It looks like it has had the easier life, cared for, and somebody loved it enough to fit a replacement ACME thread bronze nut to the rear of the quill.
I have not yet inspected and measured up the truth of these machines, but at least there is no obvious wear ridge in any of the ways, and things do turn and move.
The quill from the 9A is a different scene. It has the usual dings, but also has had some powerful, deliberate, off-centre event take out the first 122mm (0.48") of the Morse taper.
Surprisngly, the MT2 chuck taper still "sticks" into the remaining deeper part of the quill taper.
The 9C MT2 taper grabs the chuck normally, though the inside looks as if it could do with a little careful reamer clean-up.
I post the pictures for comment and advice. These are early days in the fixup attempt. The time I can post more tasteful pictures seems right now hard to imagine, but I am bound to try!
