I tried the Giffen grip and couldn't use it because my tea
bowls are not quite leather hard when I trim and the grip
deformed them. I can tap on center, but not on a foam pad,
and when i tap on center as Mel instructs on a wet wheel
head and press down to create suction the rim deforms. I
think I will try as Mudlark instructs and throw a chuck,
cover it with a paper towel and put the bowl on that. See
the Center, throw, trim video by Derek Marshall for that
technique. Best explanation on centering I have seen. Notice
the soft clay. He also has a nice tool making section.
Stay centered

Trimming using the hump:
I trim pretty soft as well and either throw a chuck wet and let it set up or
torch it and put a piece of plastic over the top. The plastic grips the
interior of the form. With a twist it comes off.
OR I use a biscuit chuck affix it to the wheel, fill the inside top portion
with clay and make the exact inverse of the shape I trimming--works like a
charm and I can change sizes depending on what I am trimming by removing/or
adding to the clay. A demo of this will be on my website in the near
future. A giffin grip can be used to hold the biscuit chuck if you wanted
to instead of affixing it to the wheel with clay.
Thank you.

How about glueing some foam pading to a small bat. Hold it in place on the
wheel with the Giffin grip. Get a texta pen, hold it firmly in place on
the foam while the wheel turns, thus drawing a complete circle. Draw
several different size circles on the foam. So when you turn, just rest the
pot on the right size circle. Yoe should not tneed to tap the pot to
centre it. Also works with other shapes, where the rim is fairly level,
but not round.
Cheers. Graeme.
