There's also a lot to be said for hacksaw parting, followed by a
facing cut :-)

I tend to use the cutoff tool only for stock 1/2" dia.

I've had similar problems. First make sure the "T"
type parting tool
is absolutely perpendicular to the work because that
type tool has no
side relief. Try lowering the tool a few
thousandths below center.
A tool ground from square stock (a lot of grinding)
with side reliefs
tends to work better for me, but has some limitation
on cutting depth.
Parting off is, to me, difficult and slowing the
lathe down as is
necessary for such operations reduces motor power.

How big a diameter are you trying to part off? A
lot of people
have difficulties with this. It gets dicey on my
7x12 on anything
more than 1-1/8" in diameter. I seem to get the
best results
slowing the rpms way down, as low as I can go with
the speed
control. Also, I make sure I have as little of
the parting tool
as possible hanging out from the tool holder.

The only tool I have problems with is
the cut off tool.
I am using a .062" x .5" HSS tool, cutting brass
and Aluminum. I
always seem to get terrible chatter. I made
sure the saddle,
cross
slide and compound are very tight to the ways,
but it still
happens.
Does anyone have any suggestions to make this
better?
I've not heard of anyone else complain about
this, so I think it
must be something I am doing.
