Thanks - I am. Your question brings another question to mind: Would it be
possible/sensible to use a parting tool to the right of a fixed steady?
(googling did not really help in this matter)


Possible indeed. However, real care needed for

1. allignment -- when I have to do that, I routinely use a dial indicator
to set the work in the steady.
2. tool height adjustment -- depending on the diameter and how much you're
cutting, you may have to change this. For a solid piece, that is -- for
tubing, probably not.
3. go really slow. Use the back gear. But note that the feed has be
reasonably high -- as for any cut off operation. Too small a feed and the
tool skips over until it digs in.
4. A lot depends on the material also. I've done this routinely with
plastic, brass, aluminum. For steel I cut off with a band saw and finish
off in the steady -- it's faster and less risky.
