Help to adjust apron feed lever on SB Heavy 10"

segerham
 

Hi, I am in the process of getting my heavy 10 apron put back
together after a thorough cleaning and paint job. I am having
difficulty getting the forward/nuetral/reverse feed lever to move out
of nuetral position. The problem is that the rod and cast finger
that bolts to it does not seem to have enough lateral movement to
disengage from the notch behind the lever, and go into forward or
reverse. The rod pushes over into the half nut. I have fiddled with
the half nut lever and feed lever, but the only fix seems to be that
the half nut gib must be very, very loose. I can't believe this is
correct. Does anyone have any experience reassembling these aprons?
Is there someting I need to do? Thanks


Re: Heavy 10 spindle speeds ???

Thomas G Brandl
 

Steve,
There are other aplications that use plain bearings that run at
higher RPM. For a 1 inch diameter aluminum piece your RPM would be around
2000 RPM. I fly model R/C airplanes. Some of the motors use plain bearings
and others use roller bearings. Most think the roller bearings give and
advantage in performance. According to one manufacture (Fox), there is no
performance gain. But the plain bearings do take longer to break in. I do
think even our lathes would need and initial break in period. I do have a
CNC lathe that says to run the spindle at a certian RPM for a few hours
when new. Also, Car motors use plain bearings. They reguarly run in the
2000-4000 RPM range. I would recomend to use synthetic oil or lubricants.
THese can take a higher load and RPM. From what I've heard, they generally
show little or no wear in car motors at 100,000 miles. I do use them in my
car. The main draw back is cost. $1.50 for regular oil vs $4.75 for full
synthetic. I justify this with longer intervals in oil change (10,000 miles
vs 3,000 miles) and a 2mpg increase. Back to model airplanes, there are
ceramic ball bearings available for them. From what I understand they only
are needed when you are looking at 30,000 RPM. (OK a bit of the subject).
Still, I think the main advantage of the ball bearings in this aplication
is ease of maintenance. With wear the bearings create an air gap or the
seal goes out. This causes an unreliable idle. The ball bearing can be
rediably replaced.
Maybe someone on the board has direct experience running aluminum on
a heavy ten for a period of time. Still, I wouldn't be to concerned and run
synthetics. Feel the head stock during running. It should get warm, but not
hot to the touch.

Subject: [southbendlathe] Heavy 10 spindle speeds ???



Hello folks,

Here's another newby question :-)

I have not found any information on on the speed ranges of the
spindles. I want to be able to turn aluminum and small diameters.
From this, I assume I'd want speeds up to 2000 rpm ?
From the parts lists I've looked at, all of the spindles turn in
plain bearings. Doesn't this effect the rpms a lathe will turn ?
Do any of the South Bends use ball or roller bearings for the
spindles ?

Thanks,

I seemed way to heavy for a home shop to me, and you don't see many
parts posted. I was hoping for more information to pass along.. I
think my fiend would be unhappy with this - better to get something
13" or less in his application. Thought I would ask experienced
(instead of my gut feel) opnions before opening my mouth....

Jerry,
I ran one in a maintenance shop for five years. The feed change
levers are very susceptible to breakage from careless forklift
driving
(by me) and they certainly are heavy. What else do you want to know?

Can you send that one also? 16" southbend 12645 HKX 15

Re: Smallest Lathe with Taper Attaachment ?

gorvil
 

Don't buy a Clisby. It is truly a toy. I bought one and after rebuilding it with bronze bearings instead of aluminum on the leadscrew, turning a 4 step pulley system, adding a sewing machine motor instead of the tiny 12 volt DC motor it comes with, refitting it with the old knobs from my Sherline after replacing the Sherline knobs with larger ones and making a gib system that worked, I gave it to a jeweller friend of mine to turn waxes for casting. He's happy with it now but nobody on this list would be unless as an improvement project like mine.

I don't know the smallest to ever have a taper attachment, but the
Sherline has the ability to swivel the lathe headstock to allow turning
short tapers. You could also look at customizing a Taig and making the

Fortunately, I found a used replacement. Kim Steiner

I'm just curious,how many members have this setup on their lathe.
I really don't see it that often,does anyone have an opinion as to
why,was it too expensive because I really like mine and I think it
is a great space saver.Would anyone have any old books with a price
for this setup. Thanks Scott.

Re: What DRO do you use?

Jeff,
Mine is not a Southbend, but look at my web site and you will see how I did it on mine. I have the saddle and the cross slide rigged up using inexpensive encoders, some cable, a freeware program and an old 486 computer. You will find the link in my tagline and this series of pages starts with my mill/drill (and has the software and interface information.

At 06:06 PM 1/7/03 +0000, you wrote:

Has anyone had success doing this for under $1000? A picture of an
installation would be dandy.

They are proprietary. 3AT is Atlas, 3C is Cataract, a Hardinge brand, and I
don't know the source on 1A.

Once upon a time machine tool manufacturers made every piece of there
machines themselves, virtually nothing was bought in from outside except raw
materials. If you were going to offer a collet system for your lathe you
designed and manufactured your own.

Eventually manufacturers started buying in certain components. Now chucks,
bearings, tool posts, gears and pulleys, and collet systems are often
supplied by specialist manufacturers. Most of the collets we're now familiar
with were designed to fit the specific lathe. It wouldn't have made sense to
a manufacturer to copy somebody else's design and to do so would almost
certainly have been a violation of patent.

Now you are free to adapt whatever collet system you prefer to your lathe.
But I will admit that the prolifc range of existing types of collets, often
with only the most minor differences, can be confusing and frustrating.
