Armorer -- That's a really nice lathe and doesn't look like it has seen much use. What is the back story on it? How did you find it and what is its history?

Thanks! Here is the story behind it. It was ordered by a man in Lincoln, NE and shipped to Baker Hardware in December of 1948. He worked for the railroad and used the lathe to make model trains. When he died his son inherited the lathe and it sat pretty much dormant since then. When he got a divorce a year ago he had to sell everything in his shop to downsize. He put it on Craigslist for $400 and I bought it sight unseen. It came with the bench which had 4 drawers full of tooling, as well as 4 buckets full of tooling. I didn't really know how good of shape it was in until I got it home and started disassembling it for cleaning. There wasn't anything wrong with the old girl, just decades of gummy oil with dust and dirt. And, of course, the gear cover hinge pin is loose. I still need to fix that.

I am in the process of making a new bench for it out of a steel base and a thick concrete top.

Afternoon gentlemen. I just picked up a heavy 10 that I am trying to date. The Southbend serial number page is a little confusing so I am looking for some other opinions. I can't post pics for awhile, but here is the info. model # CL187RB, serial number #2375R , 4.5 foot bed. It has a taper attachment, extended range gearbox, flame hardened bed. The apron has the lever clutch instead of the " star wheel " type. I come up with a 1988 date, but I am probably wrong. (hope not) I intended to wait till spring to buy a Southbend, but this one was way too nice to pass on. believe it or not, I see no backlash at all on the compound, about .010 on the crossfeed, and no noticeable backlash on the carriage. I believe this was a toolroom lathe, but then again, I could be wrong. It runs extremely quiet even in backgear. I paid the same price I would of if I had bought an 80 year old SB. Plus it came with the heavy sheetmetal bench, 3 and 4 jaw chucks, a steady rest, a removable plexiglass chuck guard, a 3 phase motor on the lathe, and a brand new single phase ready to go in if I wish. I have been doing the happy dance since I picked it up this morning.

Nice score ! Maybe some of my luck rubbed off (hee hee). I'm almost envious but then again I have the Harrison M300 for competition.

I bit the bullet over the weekend and picked up a SBL 9a lathe so I can finish reconditioning my Van Norman mill. Overall I'm very satisfied with the purchase. Although like any piece of used machinery there is room for improvement.

I am a little concerned about the serial number stamped into the bed. 21890NAR9 is the serial number. According to the formula of (21890^0.0059)*1812 the bed comes up as 1922. Any suggestions to the actual year?

This week, I should receive new tools for the lathe. Once I finish turning new bronze bearings, I'll work on a better work bench designed for the lathe. Here is a picture tonight after setting up the countershaft, adjusting belt tensions, and giving it a spin.

I think you'll find that the spindle runs directly in the cast iron head stock (no bronze bushings) unless someone fitted them in the past. Looks like the lathe hasn't been too abused, your iron bearings will likely be OK and best left alone if possible.

Would require line boring to do fit bushings; tough task, although it has been done.

The bronze bushings are for my countershaft on the van Norman mill. One of them is worn past 0.025" causing the second bearing behind it on the shaft to over heat.

I couldn't justify buying a project lathe when I needed a good lathe to complete the van Norman project.

A little history from previous owner-lathe was bought by an ametuer machinist (supposedly new) and willed the lathe to his best friend's son. The son barely used it and left it alone for the past 13 years. Then sold it to the owner I bought it from who used it for BB gun smithing. He sold the machine to me because he found another 9a that he liked more.

1943 10L. Has the war production badge and very limited use of brass. The collet holder is the original wood. Came with a bunch of tool holders, and a couple phase II QCTP's that I'm going to end up selling to get an Aloris AXA. 3 phase motor will get a VFD upgrade. I'm going to run it as it but clean out and install new software. It will eventually get new paint. Probably the original OD green.

Well I got this one:

And this one:

SB 9A.jpg

Then I got a good deal on another 9C so I bought it to keep in a box for spare parts. It was dirty but basically in very good shape. Then I found a 9A cheap that wasn't in very good shape at all. So I kept that one for spares and decided to clean up the other 9C I had and sell it.

I disassembled and checked everything but the headstock, which seemed fine. Not much wear to the bed when I checked it with a machinist level and precision square. I think it cleaned up nicely:

Now I wanna keep it. Oh well.

My South Bend 14 1/2...


20161121_115018.jpg 20161121_115006.jpg

As I bought it... pretty nasty...

20161111_150748.jpg

It had not been powered up in 20 something years... but it seems to be very tight and cuts well. I have not had a chance to thoroughly test it, yet.

Has anyone ever spray welded a lathe way to build it up and than ground the lathe way straight.I have an old South Bend lathe that someone did a lot of tool post grinding on.There is wear under the chuck about twelve inches long.The rest of the way is still straight and not worn.My thought is to repair this area and build a grinder that would ride on the non-worn part of the way to grind the area to be repaired.I have seen shaft bearing surfaces spray welded and than reground to repair the shaft.Thought this might be a way to fix this problem.

Don't have any idea why so many pictures posted.could someone please tell me. Thanks
I don't think anybody minds too much. Sometimes it takes a minute for a file to load. If you keep trying to re-load it, it will sometimes end up posting multiple times.

Here is my 1972 high school 10K after referb.
I used one exactly like yours that I bought for a research division of a sign company back in '96. A sweet machine totally tight and wonderful to use. This brings nice memories. Thanks
