I've been looking for a deal on a lathe for a while now and found a 14X48 southbend I liked on craigslist. I called my dad to see if he would help me move it if I bought it and he told me to wait. He said there was an auction coming up where they were selling the last Southbend lathe from my high-school shop class. It's a 9X42 model A with the quick change gears and the cabinet/stand. The ways look pretty good, 1 tooth missing off the high-speed headstock gear but that's not a major deal. It didn't come with much tooling, but it did come with the taper-turning attachment and thread-dial which are 2 big pluses for me. I figured it was worth $500; I bought it for $340 + the cost of a single-phase motor (don't know what that is just yet but can't be too bad for a small lathe).
I would have liked to have a bit larger lathe, but I'm happy with my purchase. This will fit in my garage much better than a 14X48. I can probably do 90% of what I would want to do on this lathe. I can patiently wait for a larger garage and larger budget for that other 10%.
Projects you can expect from me in the future (next couple years).

Oversize .22lr suppressor for my Spikes ST22
Possibly an integral Ruger 22/45, but I may decided to just go with a .22 can and thread the 22/45 barrel.
Maybe a .223 can, but that's a big maybe.
Update: 8/14/12
I discovered that it's not a 9X42, but rather a 10K with the 3 1/2' bed. The 10k was built on the frame of the 9" lathes but the headstock, tailstock, and compound rest are all slightly higher to give a 10" swing. So basically it's 9" lathe for all intensive purposes but it can handle a slightly larger swing which does no benefit for gunsmithing, but still good to have "slightly better". I also discovered that the taper attachment alone is worth much more than I paid for the whole lathe. Which should offset the motor replacement. Speaking of which, I asked my dad to go to the local electric motor shop and buy me a 1/2 Hp 110V motor that can be reversed. He didn't exactly do that, what he did do was go to the shop, tell them I wanted a 1/2 Hp 110V electric motor wired with a reversing switch on it. So what I got was a motor with a bunch of extra wires and switches I had to remove. The motor was $170, the extras were $120. I only wanted the motor. With all the extras it created extra work & expenses for me. I ended up removing the switch because I liked the factory switch better (it was already mounted on the lathe in a convenient spot) and I had to made a lot of changes to get the wiring they installed to work with the existing set-up. I know dad was trying to do me a favor, but he made my life harder and cost me an extra $120. He did take the switch back home with him so he could ask if they would take it back. That will save me $40 of that $120, but the wiring job they did was NOT worth $80. I had to pretty much redo it because the insulation was cut/stripped/missing in places it shouldn't be, looked to me like somebody was a bit careless when stripping the outer sheath off the wire.
Started tearing her apart last night. I had planned to just use her as she sat, but excessive backlash in the cross-feed led me to perform exploratory surgery. #1 thing to mention is that some retard (this came from a HS shop class) welded the ball-crank retaining nuts in place. Those are used to adjust the back-lash in the cross-feed and compound-feed. Upon closer inspection I discovered that the retaining nut on the compound was on back-wards which is why the compound had a lot of backlash as well. I was able to use a dremel to remove most of the crappy weld and a nice whack to the nut with a punch knocked it free. Needed new nuts anyways, so may as well get them out that way vs ruining the ball cranks. Pulled it all apart and everything looked nice and cruddy inside. Compound rest was actually in pretty good shape, about 2 hrs cleaning gunk out and put it back together and it's smooth as butter. I won't be able to measure backlash until I get the new retaining nuts (ordered today for $9 ea).
The cross-feed is another story. The brass nut is almost completely stripped and the feed-screw is heavily worn. Compared to the rest of the lathe I don't see how this is possible. The lathe has been used VERY lightly since it was new in '72 (my dad confirmed that this is one of the lathe's he used for shop class in the mid 70's so I'm certain they were purchased new or nearly new by the school). My only thought is that it's because of the taper attachment. Unlike most taper attachments that have a telescoping cross-feed screw, the 9/10k lathes have a screw in the top of the cross-feed that releases the cross-feed from the nut when using the taper attachment. My thought is that being a shop class, enough new guys forgot to do this and put excessive strain on the nut/cross-feed screw causing wear. No worry, this is a simple fix. $15 worth of 7/16-10 LH precision ground ACME screw stock (only 1 source that I know of), $35 nut, and a few machining operations will fix this.
Further inspection has revealed a missing gib for the taper attachment (easy to make my own if I had a mill) and tight quill on the tail-stock. At this point I've ordered the manual on how to rebuild the lathe and a rebuild kit (felt wipers, oil wicks, gaskets etc) and I've decided to do a full rebuild. Depending on my schedule, this may take a while. I'll be doing a lot of travel for work in the next few months so my time may be limited.
I think I'm going to hold off on the FFL thing for now. I want to get comfortable with the lathe and fully test my abilities with a couple custom gun projects for myself before I start up a side-job. The worst thing I could do is start up, realize I'm not up to par, and disappoint a lot of people.
By the time I get this thing built up I will be into it about $1k w/o tooling, but at that point it will be very tight, and last many more decades.
