I have made foam trimming cones for years, they are the fastest, safest and
best way to trim any of the smaller type pots.
The foam rubber cone is glued to a bat so is easily mounted onto the wheel
and is automatically centered, quick easy to use. It can be mounted on a
bat so it can be used with other trimming devices such as the grip and the
versa bat system and others.
The cone rerounds rims, supports the bottoms of pots from within, the cone
is one of many foam chucks that I have made and use daily. They are easy to
make and use and can be made waterproof so one can throw extentions on
them ie; wine goblet stems, footed mugs, pots ect. Cutting the foam rubber
cones is the tricky part but a jig can be made. I would hope in the future
that I can post pictures or a video on how to make and use the foam rubber
chuck system that I have made and used for years.

For those who asked and those that are interested in the foam cone, here is
the info:
The cone is made from " foam rubber" and is 4" tall, with a 2" dia. top and
a 4" dia. bottom. it is glued to a bat that is drilled to fit the bat pins
of your wheel{ other ways of bat systems and also the grip will work with
the cone]. This foam rubber chuck is very forgiving and accepts pots with
throat dia. of 1 1/2" to 4" and up to 10" tall very nicely. It can be used
to trim wet to dry pots, will reround any deformed rims immediately and
supports the bottoms of most pots on the inside. It is very fast to use and
is easy to install and remove from your wheel. One potter recently trimmed
250 honey pots in 1 1/2 hours on this device.
The trick to using the cone is to make sure when you are installing the
pots onto the cone that your wheel is " turning" about 10-25 rpm. this is
critical,as you can not put pots onto the cone when there is no wheel
movement. As you put your pot onto the cone the foam starts to collapse and
the pot is" screwed" onto the foam, then as the foam starts to rebound
inside the pot, the pot is centered and is ready for trimming, this all
takes place in a second or 2.
The cone and bat can be made waterproof and this allows for the throwing of
extentions and feet ect.
The cone can be made or cut in different ways and this is the tricky part,
to get a true smooth foam rubber cone one must either mould or cut them,
I've done both and prefer the cut ones as they have an open cell finish and
that seems to work better. I use a medium density polyruethane foam rubber
and attach them to the bats with a "slow curing contact cement"[so you have
time to center the cone on the bat].
I hope that this is clear to everyone, as this tool is a great device and
is cheap to make and easy to use and I hope will become a buddy or right
hand that will assist potters everywhere, I've used this design for years
and used it almost daily with ease.
If anyone has any questions feel free to email or phone me.

Bryan, What tool do you use to cut the foam? How are the cones made =
water proof?

To answer questions as to what kind of foam to use, one should use a medium
to firm foam rubber for the cone as soft foam vibrates a little when
trimming causing chatter marks.
