A Steady Rest which travels with the carriage is called a Follow(er)
Rest.  A Steady (or Center) Rest is clamped to the bedways in a fixed
position.

Are you using a steady rest?  The cause of chatter on long workpieces is
often flex in the workpiece itself... and a steady rest that travels w/
the carriage is a good solution in this case.

Richard,
 It sounds like you need a follower rest or a steady rest for this
application. They are the most requested accessories for these Lathes,
so expect to pay dearly for them- especially if you are brave enough to
buy one direct from Southbend.

There is an outfit that sells very high quality castings: 

   Metal Lathe Associates
   Andy Lofquist
   814-234-3543

Has a first class casting kit from which you can make a steady rest for
the 9" SB.  Cost of the castings is +/- $40.  I just machined one.  First
class.  

You will need some help from someone with a mill if you don't have one.

Best of luck.

I second the remarks about the quality of the castings from Metal lathe 
Accessories.  They are really surperb. I machined a "T" slotted cross 
slide for my 1950 Model A 9" South Bend.  Its beautiful and looks and 
acts like the part South Bend should have made.  Also machined two of his 
castings for a large rectangular block with slots and threaded holes to 
use on both the lathe and on my mill.  I am also, amoung other things, 
machining a set of castings for two of his milling attachments - one to 
use on my Mill and the other set up for the South Bend.

His directions are excellent.  I used my mill to machine both the "T" 
slotted cross slide and the two blocks.  It takes both the mill and lathe 
to do the milling attachment, though he has a scheme to do it all on the 
lathe.

Great quality castings.

  ^^^^^^^^^^^^^                                            ^^^^^^^^^^
They are also called a travelling rest in other parts of the world.
