Hi all,
With all this talk of Giffen Grips and tapping to center, I was
wondering how many of you use trimming chucks? What are your favorite
sizes? Do you use foam to help adjust the non-round shape to sit in the
chuck? If not foam, what do you use? Do you put the chuck directly on the
wheel or on a foam covered bat? If directly on the wheel, how do you fix
the chuck on-center?

I use chucks only for bottle shapes. These chucks are usualy bisk fired .
I cover the chucks surface with hot wax resist.
Wax coating is needed to prevent water absorbing from these pieces of clay
that hold the chuck in its place. If chucks are not coated with wax
these clay pieces began to dry very fast and should be replaced too often.

I have a number of chucks that are glazed that didn't start off as chucks;
they are the result of failed (unsatisfactory to me) glazes. They are fired
to ^6. It's an alternative afterlife rather than the hammer or the wall.

I have seen Japanese potters use plastic flower pots with rounded
lips. First, they center the flower pot and anchor it with clay. Then, they usu
place a layer of clay on the lip before they place the bottle form
for trimming. The layer of clay is pressed down and then trimmed with
a fishing line trimming tool.
These flower pots come in many different sizes which gives them a
wide assortment of trimming chucks. I have not checked to see if
similar style flower pots are available in the US.
Despite all the talk of Japanese pottery traditions, I saw an awful
lot of ingenuity when it came to making pottery tools.
