trimming foot off the hump

Hank -

I purchased your faceting tool (Hank's Tool) a few weeks ago and used it
timidly on a few mugs. For the last few days I've been throwing tea bowls
with English Grolleg. I've used this experience to learn the tool and to be
bold! Of course, I had your article in the latest Pottery Making
Illustrated out as I worked the day before yesterday. Those first 7 bowls
are ok and larger than I wanted. Today, I threw with 1 1/2 lbs and got a
size I liked better. I trimmed the first 7 on a neoprene covered batt -
worked OK. The 9 I threw today will have the luxury of being trimmed on a
thrown chuck. I may bring some of them to NCECA.

Thanks for your detailed instructions and your generosity.

It's the PNW, what can I say.

Dear Tae Kim;

I usually throw a chuck on a bat to fit whatever I am going to trim
that week. Once the chuck is leather hard, I wrap it in double plastic
clay bags, where it will keep for weeks, so I don't need to make fresh
chucks for each batch of things to trim. I just center the bat on the
ever present 'pad' of clay on my wheel head and tap it down to stick.
The shape varies according to the shape of the ware I want to trim. I
usually have around half a dozen on hand at all times. Nice thing about
this method is that you can just pop off the pot to check on thickness
and tap gently back into center for more trimming. Far more efficient
than the pads of clay around the periphery.

You can see one in use here:

Cheers, Hank

hi everyone,,,,

so, yes, i throw off the hump,,, but how do you all trim "off the hump"?

i hate having to lift each piece and center it and stablize it with three
piece of clay around it. this way is tedious, time consuming and messy.

when i was learnign to throw, people would make those foot trimming hump an=
d
put the piece right on it, and somehow, the piece was centered perfectly an=
d
it didn't bounce or get yanked off the trimming hump as the piece was
getting trimmed. not sure if those were greenware or bisked,,,, anyone hav=
e
any info on this technique or any other technique that would allow me to
trim my gazzillions little pots fast?

thanks all

Tae, I throw off the hump all the time, find it to be an effective
way of making a bunch of little bowls. What I have learned, from
practice, trial/error and finally watching a Koren master do his thing
at a workshop this past December follows:
Don't be concerned about leaving extra clay at the bottoms of the
pots when removing them from the hump. This helps them hold their form
when being taken from the hump to your board. The extra clay clay can
quickly and easily be trimmed by "getting after it" when you trim.
To quickly center the pots for trimming either do what is called
"tap" centering which is where you quickly "tap" the spinning inverted
pot to be trimmied into center with your right or left hand, use your
left hand to center as if you were centering wet clay, use a Giffin Grip
which is a GREAT tool for this sort of thing, or use the small clay
"cookie" method which I believe you are describing.
The Korean Master whom I was fortunate enough to see used the
latter. He just had a small pancake of clay in the center of the wheel
which was slightly domed. He would put the inverted bowl on it close to
center using his hand to center as well as he thought necessary and then
it was off to the races. He really got after the trimming. No muss, no
fuss. Just watched the clay peel off in long strands very quickly.
He was working full tilt boogie, using his left hand on top and the
side of the pot to keep it pretty close to center and trimming with his
right. Both hands worked in harmony. A pot took him less than a minute
to trim. He did not use any clay coils to hold the pot in place, just
his left hand. The trimmed pots were then quickly placed on a ware board
directly in front of him. Keep in mind that he has been working in clay
for close to forty years and that he has literally thrown and trimmed
many thousands of bowls.
Hope this helps

Tae-
At the risk of sounding overly commercial, I would highly recommend a Giffin
Grip. Quick, simple, and accommodating. For me, it's an indispensable tool
for trimming all the shot cups ("Warning shots", I calls 'em) that I throw
off the hump. I use it for lots of other stuff, too.
Onward,

Hi Taegello,

I usually don't bisque mine, but keep unfired chucks damp
in plastic bags. Throw a tall cylinder making the top so it will
fit the inside of your pots nicely. If it fits well, then it is
easier to keep the pot in place.
