Hello "topguntml",
First off I would not recommend doing any cut-off/parting-off work
between centers. Mert has described how to do it but be very careful
as things can get very exciting quickly. Also using the Steady Rest
could help with this and also facing off the end where you center
drilled.
For a new Horozontal/Vertical Rotory Table take a look at New
England Brass and Tools site as they are now offering a 3" diameter
rotory table. It doesn't look exactly like the one that Martin
bought a year or two ago but is close. It is larger than the
original Indexing/Dividing Attachment though and it is about $115.00
(I think).
Best, Cary Stewart

I am learning and having fun, so please bear with me on some newbie
questions. I have a DB200.
1) Cutting Off: If you are supporting a workpiece between
centers or
even just on a chuck, what are you supposed to do when you get the
part just about cut off? If if falls off, it will hit the ways.
It
is still rotating so you can't grab it.
2) How does one match up at the point where I need to rotate the
workpiece after turning between centers? I can only cut to the
point
just before my cross slide hits the chuck or the lathe dog. Then I
turn it over to turn down the part that was previously in the
chuck or
lathe dog. I can never seem to get it totally matched with the
previously turned section. I usually end up with some sort of a
mark,
either high or low.
3) Do people tend to leave their belts on the pulleys when they
are
done for the night or do they tend to take them off? Do the belts
last longer if they are not under tension or doesn't it really
matter?
4) How does one face a workpiece when using the live center?
There
doesn't seem to be much room to get a cutting tool in there to face
the workpiece.
5) I don't have an indexing attachment. Are there any commercial
rotary tables that work well with the Unimat? If not, has anyone
made
the rotary table as described in Rex Tingey's book available in the
Files section?
Thank you for your answers.
