South Bend 11", catalog no.111-a

Hi all,

I have an opportunity to buy a 1940 11" x 4' south bend, catalog number 111-a, for a good price. It needs a little TLC, but appears to be pretty complete.

I was able to find some information on the 111-a in catalog 100b, which tells me that the spindle bore is 7/8" rather than the 1-3/8" of the 10L. That's not a dealbreaker for me, though the larger bore would be nice. I'm guessing the spindle threads would be 1-1/2 8tpi then?

My main question is whether the construction of the machine is more similar to the heavy 10 (10L), or to the lighter 9" machines? And if it's the latter, is it usually better to hold off for the heavier version? (I'm guessing that question will get a divided answer!)

The price is good, but it's a long way away so getting it would involve calling in some big favours...

Thanks in advance,

Lee

I believe that I have the identical lathe (for 30 years now) delivered in 1941. I am guessing at the answers here, but I agree the spindle bore is 7/8" and the spindle threads would be 1-1/2 8tpi. The construction is definitely not a light weight 9" machine. I have enjoyed this 11" lathe for the 30 years, and have used it in my business. I think you would also enjoy having this.

Might be more like the small bore heavy 10, or the pre-war heavy 9".

I disagree a bit. I think you will find that the spindle threads for the 11" SB are 1 5/8" - 8 and not the 1 1/2 - 8 like on the 9" SB. My 11" SB (model 411) was built in '39. Here is a page from SB's catalog around that time:

Thanks everyone for the input. I decided to pull the trigger based on the advice here. It looks like it comes with a 3 jaw and a 4 jaw, hopefully in decent shape so the oddball spindle thread may be less of an issue to get started.

Best,

Did you buy the overhead drive SB 11 that was posted on a local website? If so it looks like a fairly nice machine based on the pictures. As stated above it is a 7/8ths bore with a 1 5/8 - 8 thread. Parts are fairly rare and share nothing with other south bend machines. I to am an 11 owner. My lathe is in the rebuild process. Read the SB11 thread from many owners. There is a bunch of knowledge strictly related to SB 11 lathes.

Hi John, thanks for the info. No, I bought a different 11" machine with the cast iron plinth and underdrive. Actually, I'm still trying to buy it - once the deal goes through I'll give more of the details!

I have a Catalog 164-B, 11", 5' bed. Underdrive, but my motor is fried. Repulsion motor; trying to find rewind data, with little success. Had it about 3 years, and have yet to make any chips. Been stripping it down, cleaning, new felts, etc, and repainting. Maybe this year I can actually use it! zuhnc
