Headstock configuration and speed range discussion

Paul R. Hvidston
 

Does anybody have a 9" SB with a similar configuration? My 1941(?)
"Precision Model A" headstock has Timken roller bearings and no back gear
(as seen from the attached photo). Nothing hangs off of the two ears on the
headstock casting. With the headstock 3-step cone-pulley along with another
4-step jack-shaft on the floor-mount pedestal I get 12 speeds. The
jack-shaft and motor were cobbled together from pillow blocks and a
non-reversing repulsion motor. I'd like to re-engineer the power train
starting with a TEFC 1 HP induction motor and possibly add a two-step pulley
setup off the motor shaft in order to get the equivalent of a back-gear.
Spindle speeds? I'd like to end up with 25-2100 RPM. I would imagine the
roller bearings could handle the high speed safely. Flat belt? has anybody
purchased a belt and cement from SBL? Others? Cost? Is it worth machining
v-belt pulleys and getting rid of all that flat belt stuff? I read/heard
that flat belt slip is a good safety factor if you should crash your cutter
into the chuck (or whatever).

BTW, surfing the SBL web site I found more history/documentation on the 9"
series at:

Alright here is my 9" SB that has been with me off and on since 1969. The
first picture shows the lathe turning a part mounted in the 3" 3-jaw from my
7x10 with a custom aluminum backplate. The chipguard is flipped back for
this picture. 2" dial indicator depth stop above the gearbox. Phase II Enco
tool post. RF-20 mill drill to the right behind the lathe. 7x10 on the bench
to the left, bandsaw on the bench to the rear of the lathe. Second picture
same view with faceplate on to line up the milling vice for cutting a keyway
in a shaft. This time 7x10 is under the left bench.

Manuals

I just got off the phone with SBL and I learned that my SB Precision Lathe
Model A was originally shipped Jan 13, 1941. I ordered the manual for it for
$25.00 (we'll see if its the correct one). They also said parts are
available for it, but I'll bet they aren't cheap. Anyway, the URL for SBL
parts is:



and the phone number is 800-525-2843. They are very pleasant and helpful.
Just give them a call. I'll let the group know about the manual when it
arrives ;-)

While you look for a manual, the South Bend book "How to run a
Lathe", available from Lindsey Books for $8.00 is a very close
second. It has a lot of SB specific info on the smaller lathes.


Hello to the new group

Paul R. Hvidston
 

Great timing for this group. Last Saturday (12/16/00) I snagged an old (50s
?) 9" x 18" SB Precision Lathe Model A, SN 101025. I'm in the process of
learning about the specific vintage and how best to clean, restore and enjoy
this fine lathe. All help gratefully accepted.

I'd like to request that anybody with pointers to web sites, wisdom,
experience, etc. concerning the 9-inch SB please share them with the group.
If this group grows to even a fraction of the 7x10minilathe@...
egroup, we'll have a wonderful resource.

I've included a picture of my lathe, minus the floor-standing motor
pedestal. I'll be posting more pictures on the web as I work on this gem.
Maybe we can start off with pictures of our lathes in the file area of this
group since there's probably plenty of space right now.

Many questions coming up...

Manual or parts list. I have a minor manual/parts list in PDF format
that I could put in the vault.
