Hi Everyone,
My birthday (the big five-0!!) is coming soon and I thought I'd ask for a
clay extruder. Although I have lots of ideas for its use, I've never used
one and I don't know anyone who has one. Please help me out. I welcome your
advice/guidance regarding which brand you recommend with regard to material
design(is it well made), ease of use and maintenance, availability of dies,
etc. All your comments will be greatly appreciated.
Thanks,
Janet Tamulevich in Bedford, NH who'll be spending the day raking Autum
leaves.

While I do most of my extruding with my Bluebird pug mill I have a "Super
Duper Clay extruder" that I bought in 1976. I still use it on a regular basis
for small extrusions. It has held up well over years of use.

Happy Birthday, Janet.
My big 5-0 is coming soon too. I have an old Bailey extruder, about 18
years old with a large barrel and a 4" barrel. lots of dies and blanks
for innovation. works great.
I also have a North Star 4" at the Univ. which has taken a lot of
student abuse for the past 6-7 years. I have more dies for the NorthStar
but only because I haven't bought lots from Bailey for myself. I tend to
manipulate basic shapes for my own work.
Given your location (NE US) the Bailey would be cheaper to ship.
NorthStar is in Washington State.

We have a North Star and after using it for 3 years have no
complaints....Maybe I'm just easily pleased. We did take someone elses advice
when we bought it. We have even made some of our own dies for it......not hard
to do. It comes with 2 handles, but we use the longer one for leverage. I'm
just not as strong as I used to be. BUT then are any of us?
Happy Birthday!

Hi, Janet! I bought a North Star extruder last year and love it for hollow
forms. It has a 4" square barrel and lots of dies (some I ordered
separately). The only problem I've found is in extruding handles, coils,
and other small things---I absolutely cannot pull the handle down and force
that clay out through a small die! So, I still use my small homemade one
(made from PVC pipe and fittings for about $20) for handles, etc., and only
use the North Star for hollow forms. Also, if I ever move the thing, I will
re-install it higher than the recommended "waist-high" level; it doesn't
give you much leverage at that level. And I would have some sort of
bungy-hook arrangement to hold the handle up while loading clay, etc., as
now I have to hold the handle out of the way with one elbow or rest it on
top of my head while struggling to get the clay into the barrel. Come to
think of it, why DO I like this damn thing?? This is just my $.02 worth
(Canadian---which makes it almost worthless).

Janet,
Happy Birthday. When I passed that milestone, I preferred to think of
it as the silver anniversary of my 25th birthday. It helped.
As far as extruders, I've used almost every brand in some workshop or
other. Here's my take:
Randall. I have one, and wouldn't buy another. The handle's too
short, and it's too easy to pop the bottom out. But it's nice to
throw in a whole 25-lb. block at once, and the system for changing the
fulcrum point is good.
Brent. The twist-on die holder is better than the screw-on one. I
dislike the mechanism for raising and lowering the fulcrum point.
I've pinched my fingers too many times.
Bailey. I like the square shape and long handle (takes less oomph to
pull a longer handle). Same fulcrum mechanism as Bailey, and the
screw-on clamps for holding the dies are a pain. But if I had to buy
a "big-name" brand, I'd buy this one.
North Star. The one with the 12-inch or so barrel is a joke. A toy.
Way too small a barrel unless you're only making tiny shapes.
Scott Creek. Never used one in person, but I've seen them. Has the
fulcrum system I like from Randall, with the die holder I like from
Randall and Brent. Looks like a good bet.
Have fun.

Dai brings up an interesting point----how does one make an inexpensive extruder
out of PVC pipe? How does one set up the pushing/pressing mechanism inside the
pipe? It's going to be quite a while before I can afford the one I want.

I have used an extruder in my classroom for many years. I think the smaller
die problem is one ofphysics. To fix the problem, I have the students use
softer clay. You have to be more careful in keeping the form intact because
of the soft and pliabile extruded form, but it is easier. I always tell my
students that it always comes down to basics - the moisture and plasticity of
the clay dictates its use.Hope this helps.

Hey Paul---
You certainly are a very youthful looking 50+!
I've had a hard time finding a supply of different sizes of baby ear/nose and
enema syringes. The new ones I've found are not suitable, since they're making
them in two pieces and the top comes off when you squeeze. Do you know the
names of any manufacturers?
By the way, I finally did get my tiles back---boy were they ugly---but I did get
alot of ideas!!! Thanks for the great workshop.......

Hi Sandy,
I built a homemade extruder this past summer. It utlizes a welded frame,
handle and plunger shaft assembly, a PVC barrel and a Plexiglass plunger
disc. Standard 4" diameter round dies, such as those available for Brent
or Scott Creek extruders, will work, and/or you can make your own dies. I
had the frame professionally welded for $50.00 and the materials bill came
to around $30.00. I can send you--and anyone else interested--a list of
parts and written instructions on how to build it. I have no drawings or
pictures of it, as yet, but the written instructions are quite clear.
Cost for the plans is $5.00 (U.S.) along with a self-addressed, stamped,
business-sized envelope with first class U.S. postage ($.32) or, for
Canadian/International residents, additional funds to cover first class
postage to your location.

We had the same problem until we put the long handle on. WHAT A DIFFERENCE!
Ours is mounted with the BOTTOM of the extruder at waist level. You need it at
least that high for leverage.

A very simple hand held coil (handle) extruder can be fashioned from a =

store variety caulking gun, a short length of plastic pipe (usually 1 1/2 =

dia.) and a collection of washers. The clay needs to be very soft but you =

squeeze out a 3 foot plus length of coil in a jiffy.
Pancioli on mon 8 nov 99
One way to get extrusions to stand up is to cut them off against the die
holder--that is, drag the wire against the die holder as you cut.
THEN INVERT the extrusion and stand it up on this straight cut edge.
If the extrusion itself is not straight, that is another matter.

Wade Blocker on sun 21 may 00
Joyce, I have a Bailey extruder. I have never wedged the clay I use. I cut
a block of clay from the 25lb mass which comes in the plastic bag to fit
the inside of the extruder..The clay should be soft, but not sticky. If it
is too wet the extrusions will fall apart. I have tried wedging clay, but
always end up with a few airbubbles in the extrusions, and therefore do not
used that method.A little experimentation will show you the way. Mia in ABQ
David Hendley on sun 16 feb 03
I hate to come off as a "do-it-yourself fanatic".
Take that back, I am what I am.
The truth is, Jean is experiencing the problems you will encounter
when you buy these pre-made, pre-packaged extruder packages.
1.Yes, the octagon shape is coming out curved because the center
part of the die is not centered. If there is no way to adjust the position
of the center piece and lock it in place, you are out of luck. Poor die
design. Well, maybe you could cut off part of the center piece on
the sides where the extrusion is too thin, to even it out, but you will
end up with a thicker wall on the extrusion.
2. The "Z-bar" system is a poor design. The reason your extrusion
splits apart is because the "Z-bar" is positioned too close to the
exit point of the die. A well designed die will position the bridge
between the 2 die pieces at least an inch above the die surface, so
the clay will have ample room too heal back together before it must
be shaped by the die and exit the extruder. ANY WD-40 that happens
to land on the die would be a hindrance in this regard, so I would
not even have the can in the same room as the extruder. There is no
need for WD-40, although some people like it.
3. Clay should not have to be soft to go through an extruder. As I
said to Paul earlier today:
>Extruder manufacturers always stress that you should use soft
>clay in their machines. This is because they don't want to be bothered
>with the possibility that using stiffer clay might bend or break
>something on the machine.
Or the die, if they made it.
>The truth is, you should use clay that is similar in consistency to
>throwing clay, if you want the form to hold up after you extrude it.
It is not that hard to make your own well-designed dies. It's either
that or put up with one-size-fits all, run-of-the-mill dies that might
not even work well. Any two part die for hollow extrusions must be
designed so the alignment of the 2 parts can be adjusted and locked
in place, if you want straight, consistent, relatively thin-walled
extrusions.
The dies from many manufacturers fail in this regard.
Even if your pre-made dies work technically, you still have no say
in the exact size of the extrusion or the wall thickness.
That said, hey, this is your first attempt with the new extruder. With
practice, you can probably figure out what will work for you, even
if the dies are less than ideal.

Have you tried contacting North Star? If they are as good as Brian Giffen
you will probably wind up with replacement dies. Some of these companys are
very good when it comes to customer service.

I just acquired a North Star Extruder and have tried only 2 of the many
dies I got with it.
I'm already having problems.
1. The octagon shape tube comes out in a continuous curve. It never
straightens out no matter how long the extrusion. The only thing I can
determine is that the center blank of the die is not exactly in the center.
This makes one side of the extrusion slightly thinner than the other. Could
this cause the curving? If so how do I fix it? I don't have the tools to
re shape it.
2. When using the round hollow die the clay comes apart at the point where
the "Z" bar is. I spray the hopper with WD-40 before attaching the die so
there isn't anything on the bar. The extrusion appears to be fine
immediately after it comes out but within a few minutes it starts to separate.
General question: Since the clay has to be quite soft to go through the
dies, how do you handle the extruded shape to get it off the box without
destroying it? If you let is hang there to firm up, how do you get
anything done?

Hi Jean,
The new extruder toy like any new toy has a learning curve. There is a =
basic premise that clay is a viscous material which, when subjected to =
pressure, can be made to flow like a river. The middle of the river, =
like the clay in the center of the pugmill, flows the fastest. This is =
because there is more friction along the sides of the barrel, putting =
drag on the clay and slowing it down. The clay in the center receives a =
greater proportion of the force, has less friction and consequently =
moves at a faster rate through the machine. Designing, constructing and =
extruding from dies is a trial and error process that requires =
experimentation blended with a certain amount of intuition.
The first thing I would do would be to call North Star.
There is two reasons that I know of that will make an extrusion curve. =20
1. When hard clay is on one side of the opening of the die.
2. There is an error in the die construction. In other words the =
center is bent or not exactly in the center.
The reason the bridge separates the clay is probably the clays fault. =
Try another clay.
Clay is very important for extrusions, but in general a throwing body =
should work well.
The way to move extrusions from the extruder is to get your hands dry =
and then wrap them around the extrusion and pull away. Do not use your =
hands as a force to hold them put use friction only.

Hi Pam , i have the 5" model and like it just fine. i
extrude tile with it and really like that itty bitty
extra space, especially nice is the fact you can
utilize the diagonal, as it is a square barrel.
it works just fine
. BTW it isn't a full 5" inside diameter though...i
think the 5" is exterior diameter

I wrote a small instruction sheet on making small size hollow form dies for
a Caulking/Mastic Gun extruder.
I have it as a PDF for anyone interested.
PLEASE put "Tube Die" in the subject line when you email me if you want one=
,
otherwise I might miss that post!!

Here's what you do, Fred. Get a die blank and drill a 3/4" hole
in the center of it. If you don't have a die blank, make one out
of aluminum, steel, Plexiglas, or whatever you have around.
Aluminum is best, Plexiglas can break, steel is harder to work
with.
Now get a 1/4" diameter U-bolt. Take off the nuts, and take
off the flat plate and toss it. Position it so one leg is centered in
your just-drilled hole, and mark where on the die the other leg
sits. Drill a 3/8" hole there. Put a nut and a washer on one U-bolt
leg, screw it a half inch up on the leg, and slip it into the 3/8" hole.
Add another washer and nut on the other side of the die and
hand tighten. Now, adjust the U-bolt so it is centered in the
3/4" hole (that's why you made the second hole over-sized, to
allow for adjustments) and tighten.
Install in your extruder with the U-bolt up, inside the barrel.
This will give you a 3/4" tube with a 1/4" hole in the center. If you
want a larger hole, add nuts and washers to the other leg of the
U-bolt.

I need to make some hollow tubes appx 3/4" in diameter. I have a Northstar
stainless extruder but the dies for hollow forms don't get anywhere near
that small. I know I can make them by extruding a snake and then rolling
them hollow with a skewer but I need more than that process can do
efficiently. Does anyone know of a source for very small hollow extrusion
dies, or even a way to make my own?
Many thanks,
Fred Parker
