I am wanting to explore ways of reproduction such as the jigger for platters
and bowls (or is it a jolly for bowls?)...i have a home based
studio...anyone familiar with jiggering, jigger machines ?
Thanks,

Hello Centa, I am familiar with the process of jiggering. If you are
unfamiliar with the process I would recommend the video that Laguna
Axner Pottery in Oveido Florida sells that will run you through the
process of jiggering from mold making to making the final pieces on
your machine. I am assuming you are just learning about this process
and the video really helped me to understand the whole process. I
would also recommend to you that you find a machine made for doing
this kind of work and avoid the jigger arms that are available for
your pottery wheel. These after market arms that fasten to your
pottery wheel are not stable enough side to side to handle the loads
when making pots and they are not made for and cannot handle the
abuse of everyday use making pots. I would recommend finding a used
machine such as a Ratcliffe Jigger machine or a used Whirlwind
machine which is the U.S.A version of the Ratcliffe machine. The
Ratcliffe machine is an English made machine. They went out of
business back in the late 1980's but the machines are still out
there. Keep in mind that the expense is high to get into this if you
buy a new machine. I believe Laguna/Axner no longer manufactures the
Whirlwind machine, that was what I was told about a year or two ago.
Also, the spun aluminum pieces you make your master molds and working
molds in called "back cases" and "mold buckets" will cost you a
sizable investment and I would try to find a machine with a few
sizes of these. I have had a local machine shop and foundry make
these pieces at half the cost or less of ordering them from England.
If you have questions about the process, let me know.

I too am very familiar with the jiggering and jollying process, and have
worked in a production facility using this equipment.
Wyn, I pretty much agree will all that you have said. It's right on
target. I would like to add however, that for small runs - up to 500
pieces, a solution to the heavy investment in manufactured jigger/jolly
equipment can be found in Donal Frith's definitive book - "Mold Making
for Ceramics". In his book he describes and show pictures of methods of
construction of a jigger/jolly setup that is relatively inexpensive. It
definitely helps get around the purchase of those very expensive
machined aluminum bucket heads and back plates that are an essential
part of any jigger/jolly operation. I have worked with this and it does
work as he describes. It's a good bit of work to put together, but like
I said, it's relatively inexpensive when compared to the commercial
systems. And you can have a fair output from it.
BTW, I never found the side load to be an issue on the potters wheel
jigger arms, but found that flex in the spine of the potters wheel to be
an issue. There was to much spring in the system - arm and wheel
together - and consistent thickness control was an issue as a result. A
constant battle.

I'm very familiar with jiggers. What do you want to know?
