Oiling Mess - or What Oils do I _really_ need?

Michael Oberg
 

I know that there have been lots of oiling discussions already, so I
apologize if I am just unable to digest all the details and figure out
exactly what I need for my SB 9C lathe.

According to an oiling chart that I found online (mirrored on my
website here: http://www.michaeloberg.net/images/tools/South_Bend_9-10K_OilingChart.jpg),
I need three oils:
(1) ISO 22 for the spindle bearings & apron
(2) ISO 32 for gears and who knows what else
(3) ISO 68 for everything else

I found on MSC the following two products:
Oil - Lubricants Type: No. 10 Spindle Oil Container Size: 1
Gal. 60002136 $17.23
Oil - Lubricants Type: No. 2 Way Oils Container Size: 1
Gal. 60002151 $18.69
No.10 Spindle oil is ISO 22
No. 2 Way oil is ISO 68

I have notes from online discussions and other reference sites that
says that these two oils are all that I really need, is this true? Is
there a way to buy them in smaller quantities?

Thanks for the help,

Michael

Hi all

Is anyone ells besides me having problems with post that do not make
it on to the list or take one to two days to get there???? I sent one
two days ago and it never made it. The second one I sent took a full
24 hours to show up. The one sent a day ago has not made it either.
Something is rotten in Denmark I am afraid.

It is a 1940, what a shame but at least you got some good from what
was left....Bob


South Bend 13

Greg Coffin <gpcoffin@...>
 

Warning - long winded narrative ahead.

There were two South Bend lathes being scrapped at a local shop, and I
was able to see them a few weeks ago. One was a 13" and one a 14".
Both had been stripped of tail stocks, QC boxes, cross slide control
levers, etc. All that was left were the main castings (bed,
underdrive, headstock, etc). The 13 had a lot of play in the spindle
bearings, though the 14 was good and tight. Well, I wasn't able to
pick them up for lack of shop space, but the recent converstation
about abrasives and spindle bearings got me thinking about getting a
beater headstock, so I enquired again about the lathes.

The 14" had already been scrapped out (what a crime!), but the 13" was
still there. When I arrived, the lathe had been completely
disassembled and dragged to the edge of a loading dock. The
"disassembler" had done his best to remove every possible bolt,
appearantly with a pipe wrench. Parts where everywhere, including the
headstock shims, but at least they were all in one general vicinity.

I picked up the headstock parts and thanked them, and as I was leaving
thought it might be good to take the underdrive cone pulley as well.
As I began pulling apart the drive, it dawned on me that I might be
able to mount the headstock directly onto the base, using a short
belt. Well, that idea didn't fly, and then I noticed the bed sitting
there, and also noticed my Sawzall.

It took about 30 minutes to cut the short section of bed. The picture
shows the final result, which I think is going to work very well for
polishing and straightening shafts. Maybe I'll do some metal spinning
as well, or aircraft propeller testing ;) My greatest fear is that
this was some rare lathe, but it was in such terrible shape that there
wasn't much else to do with it. The serial number is 84733, for those
able to decifer it. It will be restamped on the bed once I have cut
it to final length. At least posterity will be able to discover what
it once was.

If anyone has a beater 6" or 8" three jaw chuck good for rough
service, I'm interested. Spindle thread appears to be 1 7/8" x 8tpi.

Hi Dennis,
Thank you for posting the handle of the ebay seller that messed up
your 8". Word of mouth is so important for us ebay buyers.

I have just posted some photos of my 1933 8" junior in the
Southbendlathepix2 group under "Tinman's 8" Junior.

http://finance.ph.groups.yahoo.com/group/southbendlathe2/photos/browse
/e9c0?c

My lathe was originally blue-gray, but someone in my family spray
painted it black. I suspect that the old timers thought that all
South Bend lathe should be black like the 1920's machines that they
were used to. Luckily for me, most of the black has worn off, and I
helped it along in some places by scraping with a hard wood stick.
Some day when I have a second lathe for regular use, I'd like to
disassemble this one and repaint it with the original color.

Mike

Re: 3/16 HSS tools?

JohnW <John.Walker@...>

Most of mine ar 1/4" The big advantage is that you don't have to remove as much metal to
grind them into shape. I also have some 1/8" that I use as inserts in a small boring bar. In a
pinch the 1/8" can be used as a cut off tool with very little grinding.

Can you tell that I hate buying a piece of metal and then grinding most of it away :-)

Re: Extra oil holes in South Bend lathe bearing caps -- don't do it

Bob Johnson <bj@...>
 

 
Hi Dennis Turk
 
The segments you talk about explain a lot. I have a 9" model B with
these segmented brgs as you mention m/c'd straight into the cast
iron. It had a "super-finished" spindle compatible with the high speeds
you mention. Note (on your final point) that when I took my headstock
apart the spindle had seized and picked up the iron - I was able to
dress the iron off the shaft though as the brg surface on the male were
hardened and ground I reckon. Thus I have a h/stock casting with
severly damaged main/front brg and perfectly usable spindle!! This
is why I'm after another headstock!!
 
Keep up the excellent work
Bob

Hi John

OK the bearing you are talking about is called the segmented
bearing. Your comment about all the slots letting the oil leak out
its actually the opposite that happens. These slots are always
being replenished with oil and if you look at it another way your
spindle is receiving a fresh supply of oil about every 3/8 of an
inch around its circumference. The segmented bearings in the 9 inch
workshop lathe can withstand much higher rpm than the plane bore
bearing as has been explained in earlier post on this subject.

One other thing to consider in your war duty heavy ten lathes was
that there was in fact a war going on and brass and copper were in
very short supply. I have always figured that is why you see so
little bronze and copper on war time machines. This was also true
in England at the same time. Think how many bearings for war
machines could be made from just the bearing material used in a
heavy then.

We have found over time that the cast iron segmented bearing will
outlast the bronze plane bore bearing hands down. The only negative
feature of them is they can not be replaced. But on the other hand
how many 40's vintage heavy tens are out there still running with an
excellent spindle but the rest of the lathe is just total junk. One
I know of because I rebuilt it."-))) Just some more thoughts on
bronze versus cast iron bearings.

Re: 3/16 HSS tools?

Rich Dean <cmsteam@...>
 

Popular tooling??
I use whatever the job requires.
Altho it happens that the majority of my HSS turning bits are 1/4" square.
I have many 3/16 form tools in HSS and some 1/8" and 5/16 and 3/8.
The lathes here are in the 7-9" range if that helps, but I visit another facility
with 13-15" lathes and my 1/4" tools work just fine there too.
I use brazed carbide tipped tools in the 1/4-1/2" range.

Hi All, I used a 3/16  HSS  blank to make and use as a keyway cutter this morning.  But have never used as a turning tool...   Mike G.

I'm using 1/4 inch stuff cause I had several to begin with before I
bought my 9 inch. Works fine for me. I do, however, have a couple of
boring bars that use the 3/16 bits.

Re: late 30's 9 inch 5C collet lathe

Hey Den,
 
If all that was available were the photos; I would be arguing, till blue in the face, that that machine is a 10L! I'd be sooooo wrong, huh? What is and why is that shaft protruding from the gear box cover?

Hi all

Just a heads up on a auction that came up today. This auction is for
a 1938 or 39 T series 9 inch tool room lathe with a 2 1/4 - 8 spindle
and accepts 5C collets. These are really quite rare as this is only
the second one I have ever seen. This lathe for all practical
purposes is the 1940 heavy ten or was the predecessor to it. If you
take a look at this lathe up for auction you will not be able to see
any difference between it and the later 10 inch machines.

Hello – I'm new to this so bear with me, I recently picked up a

But
the
top of the compound is too high for the lantern post and size 0

tool
holder from an old 6" atlas (don't ask) and the compound is
still
barely low enough to center the tool bit.

The machine was missing three pieces just as the seller had
pointed
out – one was a cross slide gib that has me thinking maybe the
cross

I'm
figuring it would be nice to obtain some height measurements -
from
the center of the HS spindle too: 1) the top of the carriage
(bottom
surface of dovetail) 2) to the top of the cross slide (compound
mounting surface) 3) to the top of the compound (toll holder
mounting
surface). If some one could take a few measurements for me I
would
surely appreciate it. Or maybe there are some other suggestions
out
there that might help.
