I'm attempting my first hollow vessel. I've completed the outside to my
satisfaction and am in the process of hollowing it out. I drilled out
the center and used a bowl gouge to get the initial hollowing complete.

I'm now trying to hollow the sides out with a smaller Sorby swan neck
tool, but am getting what seems to be excessive chatter. I'm keeping the
straight part of the tool on the toolrest.

I'm convinced the tool is sharp enough and I'm hollowing from the bottom
of the vessel to the side and from the top to the side (all downhill) so
I don't believe the chatter is from going in the wrong direction. My
impression is that with light passes, the chatter goes away, but it will
take me *forever* to get the bulk of the walls thinned.

What is/are your preferred tool(s) for hollowing vessels and, in
particular, for the "bulk hollowing" after you've set the vessel depth
and done any initial bowl gouge work.
