It's going to need some work.

I am up to my ears in a rebuild of a Delta Rockwell 11 (you can find my thread on that forum) and needed the use of a lathe to make several shafts and odd-sized bushings. I learned that a friend of mine had a lathe that belonged to her late husband, whom I knew only slightly before his passing. She said I could use the lathe if it would work. I went to take a look and found this SB 9A looking pretty sad and lonely, not to mention covered in rust, grime, and bird poop. Nevertheless, I fired it up and did a couple test cuts and found it actually functions. I found several live and dead centers, a 3-jaw and a 4-jaw chuck, a collet closer and a set of Hardinge 3-C collets, but no adapter or spindle thread protector. The lathe has a taper attachment as well. All were covered in a layer of surface rust. The motor, the 1/4hp original, works, but has to be hand-started.

I went to her and threw out a couple options to her. First, I told her I'd like to buy it. If she didn't want to sell it, the second option was to take it to my shop for a couple months, where I would clean it up and adjust it, then use it to make my parts, then return it. I told her I thought it was worth, in its present state, about $3-500, but that if I took it and cleaned it up, she should be able to sell it in the $1,000 range. I felt like this was an honest assessment, after having watched the market around here for several months. She took that information to a close friend of hers who is a machinist and owns a welding and fabrication shop. He confirmed my assessment and she returned to me with a price of $500, to include all appertaining tooling and accessories. I accepted the offer. When I went to pick it up yesterday, I told her there were several parts that I was sure her husband had, but I didn't see with the lathe. She allowed me to go through his workshop looking for parts (that was a chore, since her hired hand has literally stuffed the workshop with junk since her husband's passing). After some serious digging, I came upon a small tool box. I was happy to find the box contained the collet adapter and thread protector, a set of Rivett collets, several items of Starrett, Brown and Sharpe, and Mitutoyo mics and other measuring tools, as well as several dead centers, bits, and other small items. The one thing I did not find was a faceplate or dog driver. Anyhow, she threw the whole tool box into the deal.

One thing I got was this tiny little milling attachment-looking thing. Cutest thing you ever saw. Pics below. The graduated collar and handle look like South Bend items. If anybody has any information on it, I'd like to know. There are no manufacturer markings on it.

I spent all day yesterday disassembling and cleaning. It's not in as bad of condition as it appears. Most of the "rust" on it turned out to be just gunk and is cleaning off, but I have never in my life seen so many mud-dauber wasp nests! I also found that every oil hole on the machine was plugged with cut-bee and mud-dauber nests. Everything feels tight and smooth, though. The chucks, centers, and other tooling is cleaning up nicely in the rust remover fluid (I found that heating it in an old crock pot on low enhances the rust-removing action). As I clean, I am finding that the 2-3 coats of paint are essentially dissolving and chipping off in large chips. I won't be able to paint it immediately, but will get to it as soon as I get the DR lathe reassembled. I will clean the headstock, end gears, and QCGB this week and hopefully put her into service making shafts and bushings for the DR.

I'll post more as I progress. The parts on the work bench are from the DR. The SB parts are in the crock pot being de-rusted.

Definitely a very fair deal, especially for a taper attachment and the extras. Not sure about the milling attachment. It is not SB, that much I'm sure of. But it looks pretty serviceable for small work. My first guess is that it is off a Chinese machine.

Underneath all that bird poop is a jem of a lathe and finding the accessories is very nice---kroll

I think it's probably been around longer than the Chinese have been making lathes.

Just figured out I am missing the right side bed bracket for the taper attachment. I imagine that's going to be a difficult piece to find.

I'm going to need new drive belts. I plan on using a ribbed serpentine for the headstock belt, but wondering if anyone has a part number for the motor drive belt to the big pulley. I expect a comparable belt can be found at the local auto parts store, no?
 
oooh it looks like a long bed too... $500 worth and a free lathe. Motor needs a push? I bet 10 bucks the centrifical switch is just dirty squirt of brake cleaner will fix that. You get the score of the month award !!!!!!!
 
42" bed on it. Somebody at some point appears to have used the end of the bed for an anvil and apparently used a cold chisel to cut something. My bet is the hired man who handles chores on the farm after the old man passed away. Heck of it is that he did it right on top of the serial number. Not sure I can make it all out. I'll give it a shot tomorrow.

Finished the cleanup today...well almost all of it. Just gave it a sort of "spit-shine" for now. I need to get it working, so I can get it making parts for the DR11. As soon as that's done, this baby will get a truly worthy cleanup and a new paint job. During cleanup I uncovered three different colors: original light green-gray, dark gray, royal blue. Most of the paint is chipping off or simply dissolving as I clean, so a lot of the castings are now bare metal. The good part is that apparently I'm not the first to go through this machine. So far I have yet to come across any parts that look like they need to be replaced, except the belts. Many of the gears still look pretty new. Even the lead screw looks very nice and very little backlash in the compound, although the cross slide has some.

I did find, however, that I am missing the bed clamp bracket for the taper attachment and the back side bed clamps for the saddle. I'll need to track those down.

The rusted parts are cleaning up very well. Got the 4-jaw cleaned up and installed on the lathe today. The 3-jaw is in the rust remover crock pot tonight. Got the taper attachment and the end gears cleaned up. Decided the QCGB looks ok, so I decided not to pull it this time. Just clean what I can reach and lube it.

I'm awaiting some Shars dial indicators, a magnetic base, and some way and headstock oils. By the time they get here I'll have the motor gone through and cleaned up. Once those items arrive I'll be able to get things leveled out, set up, and start making chips.

More pics tomorrow.
 
Finished the cleanup and actually did a couple test cuts today. I don't have a precision level, so I turned a test piece about 9" long from a scrap rod I had. Got it to within .0005 on both ends. I also disassembled, cleaned, de-rusted, lubed, and reassembled the 2-jaw today. Feels nice and smooth now. I did the 4-jaw yesterday. You see the 4-jaw on the lathe. The lathe runs quiet and everything feels smooth and tight. Still doesn't look like much, but I won't be able to remedy that for a couple months.

I started on a new bench for it today. I had some 2x2x3/16 steel tube on the shop floor that was intended to become a belt grinder. That will have to wait. Need a bench now. I used the 1x2x1/8 that was supposed to become my welding cart for the crossmembers. Ran short on that. I'll have to finish it later this week. It will have drawers, a cabinet, shelves, and leveling feet when completed. Should add some weight and stability to the machine, which the old wooden bench does not.

Received my SB overhaul kit (new wicks and wipes) and the manual this evening. I'll hopefully get those installed this week as well.

Also received my new Palmgren 250 milling attachment. That will allow me to cut my own keyways and do some other limited milling.

And now a question for all you South Bend afficionados. The serial number on my lathe appears to have been purposely obliterated. Any ideas as to why that might have been done?

As close as I can make out, the serial number is US 23 179323. Could be 179293, 283? 288? 388? Does the US mean country of manufacture or did it once belong to the US govt?
