I am currently in the market for an extruder and would appreciate any advise,
as to manufacturer.
Thanks

Susan;
Scott Creek makes an excellent extruder, with an iron frame and aluminum
barrel and dies. The round barrel is easier to clean than a square one, and
the fact that it is aluminum means that it won't rust, making it ideal for
working with porcelain or other white claybodies.
We've got two in stock at Pine Ridge; come on down and take a look at them.
We've also got a multi-shape die for handles and a hollow-die kit for
tubular extrusions. The extruder itself includes several aluminum die
blanks as well.

Peter Pugger makes excellent deairing pugger/mixers, in several sizes PM100,
PM50, VPM30,VPM 20.. Go to www.peterpugger.com to have a read about them.
Mine is theVPM30 and is wonderful. I don't use it for mixing as much as
reclaiming, or even just getting new boxes to good consistency for working
with. I've only had it for just over a year, but it's been working pretty
solidly and is exactly what I needed. Saves war and tear on my arthritic
hands. Wish I'd had is a long time ago!

Have used a Brent for many years with my students and it has survived
them very well. Decided to replace it as it has a system where the
plunger is attached by means of tension against a pipe. This has a
tendency to slip quite suddenly and several of my students have been
hit in the head, though I advised them not to stand directly under
the plunger arm.
Also have a Randall, a big thing. Holds about 12lbs. of clay. Makes
large and small hollow forms.
Was thinking about a Northstar, but some folks complained about the
"Z" brace for the inner die causing problems.
Finally chose the Scott Creek. It has a slotted system to put in the
plunger arm which will be much safer for my students. I think it will
be heavy enough to suit our needs. Was looking at the Bailey, but the
budget said no.

Oh! So I'm not the only one! Mine seems to bend out of shape no matter how hard I
try to treat it carefully. Would anybody else having this problem please let me
know and tell me what might help?
