Hi, Pat,

The hand extruder that I got from Georgie's (in Oregon) looks very much like
what we call a "caulk gun" in the US--though the extruder is about twice the
size of a caulk gun.

You insert clay into the end, place the die shape of your choice on the end
of the extruder, and screw on the open cap on the end. To extrude, you
squeeze the trigger. Out comes the extruded clay in a long "worm" from the
center of the die.

I find that I prefer to use a slightly more moist clay in such extruding to
avoid cracks or slight breaks in the extruded clay and to make the job
easier on my hands, which are at least slightly arthritic. I let the clay
set up on newspaper for a bit before using.

Hope this helps.

Dear Pat,

The hand extruders we encounter (and make) are very like a Mastic Gun.
The one we make from a Mastic Gun frame, uses 55mm diameter plastic
drain pipe for the body, and discs of wood or plastic both attached to
the plunger, and slightly larger, for the dies. It is not necessary to
attach the die plate to the bottom of the tube; the pressure from the
plunger keeps them both together and there is very little leakage.

I was curious about the clay guns, also. A friend of mine has one, and since
I normally extrude coils, and not huge amounts, a clay gun would make a great
Mother's Day present from me to myself.

I got on line and found several sources, including this one:

Hallo,
Thanks for the various instructions.
Pat.

It is S-I-M-P-L-E to make a hand-held extruder from a caulking gun.
Complete instructions and photos by Fred Sweet are in the book
"The Extruder Book", by Daryl Baird, published by the American
Ceramics Society.
You could buy the book, make the extruder, still have lots of money
left over, and be inspired by the hundreds of pages of information
in the book.
