Re: Metric Thread Dial

Hm I don't feel particularly sharp today and have  not in the past thought about why the thread dial works - But would the imperial still coordinate the position of the carriage and the lead screw in metric operations on the imperial lathe. -if this is completely silly, ignore.

Conventional wisdom is that the normal threading dial is not useful with the transposing gears, no doubt why you are interested in the metric thread dial.

I have read a contrary opinion, that it will work if you reposition the carriage the same place for every pass (perhaps a carriage stop to the right of the carriage? might have to go on the rear v-way.) AND start on the same dial mark each time. It sounds reasonable to me.

I have been wanting to try this for some time, but haven't done it yet. Next best thing for me would be for you to try it.

For sale: 1949 9A in near-original condition with many original accessories

Jim Schwitters
 

I'm the second owner of this lathe originally delivered to the US Army at Camp Lee in Dec 1949 (per SB's serial number card).  I confirmed its working condition then disassembled it to major components for storage intending it for a grandson.  For sale in central South Carolina.  $2250 plus shipping.  I will palletize and crate in a manner fitting its uniqueness and deliver to a local shipper that you arrange.
Pictures here:  https://groups.io/g/SouthBendLathe/album?id=258628  4 ft bed with all the attachments and accessories shown.  Major items include: taper attachment; steady rest; follow rest; manual collet drawbar and sleeve with 8 #3 collets (1/16 to 1/2") in original SB containers; collet rack; threading dial; milling attachment; micrometer carriage stop; threading stop; 3MT milling arbor; 8" faceplate; 5' SB/Cushman 3 jaw chuck with both jaw sets; 6" SB/Skinner 4 jaw chuck; Jacobs 58B spindle chuck; 2MT tailstock chuck, various rocker tool holders; several turning dogs and various original wrenches.  Also includes photo copy of original serial number card and original oiling and bench mounting prints.
The lathe bed is virtually unworn with no discernible ridge on the inverted Vee.  Almost no rust on anything; exceptions are several spots on the taper slide and a portion of the 6" chuck.  No signs of abuse though there are a couple minor marks of shame on the compound.  The motor does not run when plugged in but I have not checked it out.  Everything is in original paint.  Additional photos and details on request.

Thank you, however, McMaster Carr do not supply to the UK, there is no franchise visible for their catalogue of components, maybe after leaving the EU the WTO will allow a better tariff and reasonable shipping, this company would do well in the UK, we are a resourceful nation, we invent things, we repair things, we need you here, we have suppliers who are first rate, ie, simply bearings, but not on the scale of the aforementioned in the USA.

My buddy has an old 11" for sale. Been sitting in his barn for a few years. No legs as he repurposed them but the rest is there.  Cat 333-Y, serial 36232.  3' bed.  No motor, no chuck, no extra change gears & only has a faceplate. 
He's asking $300. 


Re: tune up

Depends on what you mean by "tuning up." If you're trying to get a lathe running that has been out of service for some time, the books from Illion Press are great. I've got a Heavy 10L, vintage 1941, and the book for it (with a kit of replacement wicks for the oiling system) is under $90, depending on where you get it. Ebay has a better price, Amazon maybe ships a little quicker. https://www.amazon.com/gp/product/B01K58YD2W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Search on the model you have, and they probably have the book, which I found invaluable! Mine isn't completely restored, but I've not broken anything following their instructions, either. ;)

Re: tune up

Regarding your lathe, go to the Files section of the Group. There is a file name TechInfo that has information on adjusting the backgears and checking and adjusting the spindle bearings. Should be some info on ‘leveling’ your lathe also somewhere in the files.

I've had people come up from Texas and New York though so this wouldn't be much more than a day trip.


Re: Southbend 15 lathe

The lead screw is a couple of feet too long so it would have to be cut and the end machined but it is way too long to ship so it would have to be picked up. I'm about 50 miles south of Chicago.

If it was working before you tore it apart, it's too late for you- but for others consider this

It would be a completely useful lathe in a welding shop, no worries to keep it pristine, perfect for weld prep on pipe, or as a huge weld positioner for spray welding up bearing surfaces, or worn journals, or all the other ways they could abuse it.

Plus when you go to sell it, just one phone call, one buyer, one ad.

parting out some old machine with few others looking for those parts - not that much demand + way too many phone calls and such.

This 15" SB is being scrapped. I have completely disassembled it. It was in good working order in our shop but the bed had been badly abused by a previous owner. I was able to thread and machine parts to close tolerance on it. Our shop is closed until Jan 8 and the pieces will not be available until then if you can wait that long.

Re: Getting my SB 9C working

Ondrej Krejci
 

Greetings,

Yes, SB had various managerial and labour problems, eventually becoming an employee-owned business, but it kept turning out dinosaurs.  It tried selling gear-driven lathes, the Turnado, when CNC machines had already become common place.
Its last original lathe, a nine or ten, was still available from LeBlond-Makino for an outrageous price of 15 000 USD, before Grizzly bought the name and resources.
Its backwardness killed SB.

OK

I tend to think that all of the above were true.

The 9a/b/c and 10k lathes were direct descendants of the 5, 205 and 405 lathes that were depression era exercises on the part of SBL to see how cheap they could make a usable lathe. I believe that a number of list members do good work on 405 lathes. They included such economy measures as not having a lead screw reverse lever at all. The 9A added features that were omitted in the 405 -- at least the reverse lever, quick change gear box, and power cross feed -- but the economy blood lines still show. To deny that cost was a consideration for any feature of these lathes would be silly.

On the other hand, running a steel shaft in a segmented cast iron bearing is a defensible choice for the application. I do wish I could find the article/paper I referenced in my previous email. It was not an SBL publication, but rather an academic research paper or journal article. Perhaps I still have it on my old computer. For all its virtues, I don't think it fares well at the modern, higher, RPMs called for with carbide tooling.

They did produce newer, more modern, machines, such as the turnado, but these don't seem to have made it into hobbiest hands. Their innovations probably were too late and too slow for them to be one of the few machine tool manufactures to survive.

Their management difficulties and particularities probably contributed to their lack of innovation but probably also contributed more directly to their demise. Strikes at an employee-owned company, anyone. I hear that they made it into business school text books.
