Quick and to the point.....

a deairing pug mill will save your wrists, your back, and put a smile on
your face many times over.

You'll also admonish yourself for not getting one sooner.

We use 2 Bluebird deairing pug mills in our plant. We have a new Powerstar
with a beefed up vacuum system that is quiet, quick, and the clay is ready
to jigger or RAM press.

We have an old 750 SV deairing machine that I purchased in the late 70's
that still churns out fabulous clay. I've replaced the bearings and drive a
few times, put on a stronger vacuum pump, but other than that it pugs
great clay.

Get one. You'll never regret it.

Is there such a thing as a quiet pugmill, or is that an oxymoron?

Also, what are the advantages and disadvantages of deairing or not?

I'm tired of struggling to wedge clay from the bag that's just too
deactivated. Am I dreaming that a pugmill will make it nice and easy to
work the clay?

TIA, Corinne

Corinne,
I use an old studio size Bluebird, #440 I think. They don't make that
model anymore. It is not a deair. I need to turn the clay over a couple
time when I throw plates, but other than that I just cut up the pugs and
go. Motor noise yes. I would get a deair if I bought a new one today.
Then there would be compressor noise too. Noise aside, I would highly
recomend using one and the clay from one before investing.

Bless his soul, my husband found a reasonably priced Venco deairing
pug mill for me. It's big (4 inch extrusions), it is noisy, and we
still can't get the pressure higher than 50, but, it is WONDERFUL. I
pass a box of clay mixed with recycle through at a time, store it in
plastic bags for a day or so, and then throw. What a difference it
has made:

-it is so much easier to throw, no more fighting to centre.
-my wrists feel better now than they have for a long time.
-the greenware is stronger, as is the bisque
-I still wedge a bit but only enough to get the clay shaped in the
way I am accustomed for throwing, this wedging is without effort, it
is soooooo easy.
-I've been throwing for 20 years now, and yet the pug milll clay
makes it easier to throw even walls. I'm truly amazed at that, it's
probably why the greenware and bisque are so much stronger.

I could go on, but I'm sure that you get the picture. I've used a
lot of pugmills and the only ones I have seen that really work
are the Venco deairing and the Walker.

I am interested to hear about the Venco pugmill being noisy and only
reaching 50% in the vacuum chamber. If the seal is not tight in the
chamber, that is where the perspex cover with the pressure guage sits,
it will suck in air and not de-air properly. My pugmill has a
polystyrene gasket between the hopper and the perspex and I regularly
remove this to clean dry clay from the hopper.(I don't know if this is
the right word for this part of the pugmill) To reseal I make sure
there are no daggy bits of clay on the hopper, perspex and gasket and
lubricate this with a generous amount of petroleum jelly. You can use
Silicon used for windows etc but this sets and requires too much mucking
about to remove the perspex and gasket each time it needs cleaning. If
the motor etc is noisy it may need oil in the gear box. These pugmills
as all other machines regularly needs servicing. Jeff Hill, the
manufacturer in Western Australia is extremely helpful. His address and
phone number can be found in past issues of Ceramics Monthly. Enjoy the
pug as it really made a difference to my work and working methods.
