Sheri,
Congrats on your successes getting more clay equipment for your program.
Considerarions on extruders... I have an old Brent extruder. University of
Florida Ceramics has a Brent and a Bailey with an expansion box.
An extruder with an expansion box will need a large amount of clay to fill
the box before you can extrude, even if you just want to make a few small
things. The expansion box does make it possible to make large extrusions.
In my opinion, ANYTHING that has threaded parts is not a great idea for an
extruder. Sooner or later someone gets clay on the C-clamps or the thumb
screws, and it's a fight to get things to work. The Brent has a peg and hook
attachment which I think is a better idea (especially for group studio).
I've tried the NorthStar extruder, and found the fixed pivot point on the
plunger awkward. NorthStar likes this arrangement because users are less
likely to get pinched fingers or bonked in the head with the plunger handle
(which can happen to the unintialted with the Brent shackle system).
The Brent extruder I have is an OLD one. The barrel is rusty. Not a big
problem for a terracotta potter, but might be a nuisance for a white clay
person. I don't know what the current barrels are made from.
I haven't seen the perfect extruder, but if I was getting one from what I've
seen now, I'd go for the Brent.
Linda

Linda,

Not True. If your extruder has a expansion box and you would like to extrude a s
form. You just use a dye/template that fits inside the expansion box. This way y
need to fill the barrel of the extruder and not expansion box, which can be a f
of clay.
I have the pneaumatic Bailey extruder with expansion box. This extruder is 15 o
years old.
"The Brent extruder I have is an OLD one. The barrel is rusty. Not a big

Rust...... on this extruder... none...
A dial on the extruder allows you to set the P.S.I of the plunger. This pr
with a significant amount of control of your extrusions. I would imagine t
new ones are the same.
I don't work for Bailey nor' do I own stock in the company. If my Bailey i
and still ahead of it's time. I would love to see what the new one's are l
Before I extrude I spray the dye that I am going to use with WD-40. What d
to lubricate your dye's?

PJLewing@aol.com on sun 7 jul 96
I've used a lot of extruders over the years in the course of doing workshops,
and I think I've tried all the major brands.
Randall- I have one- 6" round. Nice to be able to make stuff that big, but
if you're making smaller stuff, you can't get the clay to come out unless
it's REALLY soft. The handle is too short- I slip a 5' piece of pipe over it
for extra leverage, and periodically have to turn the handle over because
it's bent. Also have popped the bottom welds a couple of times. But nice to
be able to put in a whole 25# block of clay at once.
Brent- I agree with Linda- stay away from screw parts. I also do not like
the mechanism for moving the plunger up & down- I always pinch my fingers.
And I don't like having to get the clay into that round shape to load.
Bailey- Square shape gives you more versatility than round. Clay tends to
leak out around the die, and you have screw p[arts and the same
finger-pinching adjustment. But definitely requires the least force to work,
something to consider if you're small. If I had to buy a major brand
extruder, it would be a Bailey.
Scott Creek- Don't see many of these. Too bad. They incorporate a lot of the
best features of Brent, Bailey, and Randall.
North Star- A joke. Unless you only want to make tiny things, you'll be
reloading after every pull of the plunger.
The suggestion about WD-40 on the die is a good one, but spray the inside of
the barrel and the bottom of the plunger, too. It will make cleanup easier,
prevent rust, and give you smoother extrusions.

Rod, can you explain this? We have dies that are attached to the bottom of
the Bailey barrel with C clamps. Does the die you're talking about fit up
into the barrel before the expansion box? How is it attached? What does the
die look like? We don't have the pneumatic variety. I dont' know if that
matters.
Thanks.
Linda

By now I'm sure you have saw several excellent replies to the use of the
Bailey with expansion box. The die is merely smaller and fits within the
the chamber of the expansion box. The extrusion area(s) of the die are
centered as accuratly as possible. So for this reason I make the smaller
die so it "just fits" into the expansion box. To attach or fix the template
in place just flip your "C" clamps over (the base on top of the expansion
box and the spindle moves into the box) therby securing the smaller die
in place. This way you are not filling the expansion box. For cleanup
spraying the chamber, die, and plunger with WD-40 again is a good
idea. Spraying the die is most important when extruding especially
if you are using wood die's. This will minimize warpage of the die
and extend it's life. Sparaying the plunger and the walls of the
extruder (expansioin box and chamber) make for quick cleanup
and possibly eliminate drag marks on your extrusions.

Hi all -
Can anyone out there give me advice about extruders? I don't use one in my
work on a regular basis, but I want one for my students. I've only used the
Brent model in the past, but am wondering if anyone has used the North Star,
which seems a little more affordable.
Thanks,
Jonathan in Yonkers

I have a Northstar extruder at school. It's fine. . .lots of shapes
to play with. Barrel is 4 x 4". It is old and no problems.

A friend without a computer has asked me to let you know that he is making
4 inch steel extruders (WITHOUT DIES) and is selling them for $200.00
Canadian. If you are interested you can reach Jason Stenzel in Calgary,
Alberta at 403-932-2866.
Margaret Arial on fri 31 jan 97
Got any more information on what kind of an extruder this is i.ei. design is
it horizontal / vertical does it attach to wall or tabletop, how are the dies
held onto the end, what is the length of the handle , is it a smooth
pull and extrude?:<
David Hendley on mon 2 feb 98
Diane, here are some postings to Clayart from last fall.
I know you were probably thinking only of commercially
available extruders, but extruders are soooo simple to
understand and build.
1) from me:
Hand extruders are EXTREMELY SIMPLE machines.
All you need is a tube for the clay,
something to push it down,
and something to hold the die.
I've made 3.
One looks similar to a Brent extruder, with a 4" pipe barrel,
one has a square barrel a la Bailey,
and one was made with a car jack, also with a round barrel.
If you are a handy person, and can cut and weld metal, building
an extruder would be pretty easy.
You can usually get everything you need at the scrap metal yard.
I like best, and mostly use, the first design mentioned.
A 4" long piece of pipe the next size larger fits over the tube to hold the
die.
Bolts through tapped holes hold it onto the barrel, and a 1/2" "ring"
of the barrel diameter pipe is welded at the bottom to hold the die.
You can also have the bottom of the barrel threaded, buy a pipe cap,
and cut out the center of the cap to hold the die.
The plunger is a 2 - 4" piece of the next size smaller pipe
that fits inside the barrel.
A flat pieces is welded to one end and a piece of 1" pipe is welded
to the center of the inside of the flat piece ( do thse two steps in
opposide order).
What you now have is like a piston that can move up and down inside the pipe.
Now work out a way to get leverage to move the piston.
Look at the commercial extruders.
Some use turn buckles, some use channel iron with slots cut every few inches.
There are no tricks here. What you see is what you get, and they all work.
I wrote complete directions, with diagrams and photographs,
for the bumper jack extruder in the Sept. 1976 Ceramics Monthly.
It requires very minimual welding and is quite easy to construct.
I never liked it as well since it sits horizontally.
I don't know if it could be mounted vertically.
I'd be happy to send a photocopy of the article, but copies are
kinda expensive in my little town, so I'd like to ask anyone who
wants a copy to send a buck for copying and postage.

2) from Dean McRaine:
Aloha all
You low budget makeshifters (& shapeshifters) oughta love this one. A
friend of mine put together a very good extruder out of 3" (might have been
4") PVC and galvinized pipe. I replicated it (in my replicator, ha ha) for
about $40 (Hawiian hardware prices) but if I was on the mainland I probably
could have scavenged most of it. It took about 4 hrs to assemble. I don't
use any fancy tube dies or anything, just coils. No reason you couldn't use
fancy dies if they were the right size. Basically it's about 24" of PVC
clamped to 4' of 1" galvi pipe with a screw on coupling on the PVC to hold
the dies. Dies are 1/4" plexiglass cut with a circle cutter to fit the PVC.
The plunger and handle are thinwall 1" pipe with the ends flattened and
holes drilled for hing joint bolts. Plunger end is Plexi. I was gonna make
plans and sell them but I'd rather make pots. Good luck.
Dean
Likewise, dies are very easy to make. I make mine from
either sheet metal or plexiglas backed with plywood.
Complete instructions for making a 2-part hollow-extruding
die are included with the bumper jack extruder plans.
The best part about making your own dies is that YOU designed
and made them.
We ARE artists and designing the dies gives you creative control
over what will eventually be extruded.

The trick to using small die sizes is to use very soft clay. A rule of thumb=
is
to use clay that is as soft as the clay would be on a potters wheel just =
after
you have thrown a piece. This should still give the extrusion the support
strength needed and at the same time make it easier to pull down on that =
handle.

I've researched extruded clay work as in depth as my knowledge and
available resources will take me. Anybody know of a book which includes
a significant section on extruder usage? Thanks to Edouard posting the
Studio Potter web site (timely), I've found and ordered a back issue
that contains an extruder article but, in the meantime, am still
looking. I am exploring possibilites, of course, as well as, I'm sure,
re-inventing the wheel but feel there's something I'm missing...
Thank you as always.

In the Mojave who just blew the gasket on my second pressure cooker this
week because my mind has been out of body and into the studio even when
I'm in the kitchen.....after successfully using pressure cookers for 30
years. Pressure cookers, iron skillets (4) and glasstopped stove...sound
kind of time warp here?

<a significant section on extruder usage? Joyce Lee>>
Funny how so many of us are on the same wave length. I, too, have been
wondering about extruder books and noticed in the latest CM, Dec '98 issue, a
book review on page 28. It's for "Ceramic Extruder for the Studio Potter" by
John W. Conrad. I was planning to ask the group for any feedback on this book.
It's only $19.80 in softcover, so was thinking it wouldn't be too big of an
investment to try. But I could better use that money to buy some more clay, so
does anyone know more about this book?
Also have an question about extruders. I have purchased an extension box for
my extruder to make 6" cylinders to cut into slabs for slab molds. The ones I
made all got splits in them around the edges. Didn't matter if I put the clay
inside a form to mold or outside. Used Ellen Curran's CM article as my guide,
coated all pieces with WD 40 with a sponge brush and removed the forms as soon
as I could.
I was wondering about the way the dies are held for the center part of the
hollow die. The clay separates three inches or so from the final output, then
is pressed back together and forced thru the dies. Is the separation then
showing up later as cracks in a weak spot?

Billie Scwab on wed 16 dec 98
Regarding cracks in extrusions using center hollow dies.....I have found,
after many a separated hollow extrusion, I get best results with soft clay.
I think part of my problem was lubricant on the die itself. I apply only to
inside of extruder box.

I've only used one extruder and that minimally, but when I do use my
wall-mounted NorthStar I find it easy to load, to change dies, to
operate WITH the extended handle, and to clean. Because I am a
mechanical klutz, I avoided its use for a long time (just as I did the
pugmill). However, as soon as I finish this last series of twisty pots
and feel improved enough to move on, I'll be giving the extruder and its
dozens of dies a more thorough workout. THEN I should be prepared for
Diana's new extruder book in the Fall and David's presentation at
Denver. What I would change about the NorthStar, I think, is its size. I
believe, based on limited experience, that I might have preferred a
larger one. Remember, Bonnie, this is the only extruder I've ever used,
so beware of ignoramuses who tell you all they know.

Hi,
I have used several extruders. At school we have an old Bailey hand
extruder with 5" barrel. We had to replace the pipe that the handle
shackle goes on because it was being crushed.
My students seem to like the Super Duper Extruder and we may buy one soon.
In my studio I had a Pneumatic Bailey with the large stainless
steel barrel. This was a great tool. No rust! I was extruding 2"
square pipes to make vases from. Paid for the machine in a few months.
Paid for the compressor a month later.
The pneumaitc extruder was the only way I could make the large (6" square)
extrusions without having the marks from stopping and repostitioning the
handle. These pieces were ungalzed so a uniform surface was important. I
could extrude enough in a couple of hours to keep me assembling for
many hours.
In conclusion I would go for stainless steel in the barrel and get the
larges size possible. I found that the pneumatic extruder allowed me to
change the way I thought about using the extruder and the large barrel
"freed me up" and allowed me to explore avenues that I did not think of
before I bought it.
I hope this helps.

I have a North Star extruder and it is very underused. When we do use
it, the main thing to take into account is the softness of the clay. Too
soft and the coils break, too hard and the strenght you need to get the
leverage to push the lever is laughable. You need two of me, and I'm no
bird. But we have used it succesfully once we do take this into account.
A bit fiddly to set up, but with patience and understanding it does the
job. Hope this helps

Dear Joyce:
When you say "automatic" I assume you mean a "power" extruder. There
aren't that many to choose from, and the one you choose depends on what
you want to do with it. "Automatic" extruders can be pneumatic,
hydraulic, or gear/augur driven. Please send me your e-mail address
(they don't come with the digest form of the listserve) and we can
discuss this further offline, unless others are interested.

Hey Diane,
>From the posts I'm getting, I'd say others are definitely iterested in
the different types of power extruders (and thank you for the gentle
correction)...especially with NCECA coming up and possible show prices
offering discounts if ordered there. I bought my NorthStar extruder at
NCECA in Vegas and received a discount plus a whole box of great dies.
I'm waiting for your extruder book, too...anxious to see it.

I have a pneaumatic Baily extruder and I love it. It has performed
flawlessly for me. I have had it for 5 years and never a problem and it has
been used quite a bit. It is a good investment. The big plus to powered
extruders is as you already surely know is that you can keep both hands on
your form while extruding. I'm not sure if there are other powered extruders
out there. So I couldn't give you an opinion on them.
Cheers,
Rod

Olivia T. Cavy on thu 10 may 01
Hi Jim Bob,
2 years ago when I was looking to choose an extruder for myself, I asked
about choices, and got several excellent postings from clayarters who
have used a variety of extruders. Those should be accessible in the
archives.
I ended up spending the big bucks and buying the pneumatic Bailey, and I
love it. I bought the 4" barrel and the 9" expansion barrel, both in
stainless steel. This means I also bought the extruder model that allows
you to switch the barrels. I bought a bunch of the Bailey dies as well.
However, also be aware that in addition to the money on the extruder and
dies, you will be spending several hundred dollars on a large air
compressor if you don't already have one. The extruder won't work well on
a mini-- talk with the knowledgeable people at Bailey about the size
compressor they recommend.
This extruder allows one person (of any size or strength) to use the
extruder. Virtually all other larger extruders require 2 people, one of
whom is strong. Also it's faster to use the pneumatic than a manual model
in extruding larger pieces. I was not aware of any other commercially
produced mechanically powered extruder for the studio potter, although
apparently some people use their pug mills as extruders.
It performs beautifully-- as advertised. It is an excellent piece of
equipment, and I'd buy it again. The only thing I'd do differently is
look more seriously at Bailey's parting platform which would make it
easier for a single user to make clean cuts in the extrusions.
In the future, I may also buy a small extruder, say with a 3" barrel, for
extruding small pieces. Even the 4" barrel takes a lot of clay so I don't
tend to use it when I just want only a few little extrusions. Sometimes I
extrude smaller pieces and wrap them in plastic for future use. As Joyce
Lee has written, the 9" expansion box easily holds 25 lbs of clay, and
probably more, although not all of that gets extruded out.
I hope that Bailey has improved their assembly instructions, because they
were pretty poor 2 years ago. But the equipment is top notch and
they are very helpful in (toll free in the USA) phone calls.

I am in the market for a power assisted extruder.
I have searched the web and have only come up with one made by Bailey, which
is expensive.
I remember years ago I went to a Convention and saw a small unit that did not
have to be attached to the wall (I guess you could if you needed to) and it
extruded quite nicely. Does anyone know if there are any other manufacturers
that I cannot seem to find?
Thanks. Chris

Buy the book before you buy an extruder.
A clay extruder is the simplest piece of studio equipment you
can build. It is just a tube with something to push clay through
it and something to shape it on the other end.
There are several plans for extruders in the book. Of course
I am partial to my plans for the "bumper jack extruder". It
is very simple to build, yet sturdy and long lasting.
The plans are in The Extruder Book, as well as Ceramics
Monthly, September 1976, "Making a Bumper Jack Extruder",
Ceramics Monthly, pages 50-53.
(Old issues of Ceramics Monthly are available on CDs, so the
original article is again available in that form.)
The plans were republished in Pottery Making Illustrated
magazine, "Making a Bumper-Jack Extruder", Pottery Making
Illustrated, Winter 1999, pages 30, 31.
Republished again in the book, "Pottery Making Techniques",
(articles from Pottery Making Illustrated) American Ceramics
Society, 2004.
Daryl Baird is the moderator of the Yahoo clay extruding
group. Check it out and join at:
http://groups.yahoo.com/group/clayextruding/
Ask this group and you will get lots of opinions as to what to
look for/buy in an extruder.
My opinion is that there is no "best" extruder. Every commercially
available model has drawbacks to me. What you plan to make
and how you plan to use it will determine what will be the
best extruder for you.
My life would certainly be incomplete without an extruder.

I've decided that my life would be more complete if I had an extruder. I'm
liking the looks of the Axner Avalanche, with its stainless steel square
barrel, and I was wondering if any of you have any experience with it that
you'd like to share. Sounds like it's fairly new.
I'm also thinking about buying the book, "The Extruder Book" by Baird, not
only because it sounds like it has tons of information, but also because it
sounds like it has instructions on making your own extruder. And since $300
(to buy a ready-made extruder) is a big hit for me, I'm thinking of
enlisting my hubby to help me build one instead (if indeed I can get hold of
instructions - and if I have the necessary equipment to put one together -
I'm guessing supplies might not be too much). I'm hoping the book would talk
about what to look for in (or build into) a good extruder.

That's what you found. I have personally known one potter
who bought one and said it works fine.
With minimal metal working skills you could build it yourself
for less than $50, $30 if you shop at the junk yard.
