Home-Made Extruder and Discs

When I updated my old website and launched the new one, some of the old files disappeared. One of them was a set of instructions for making your own clay extruder at low cost. These instructions are now available here. (You can always find the link to these instructions on my blog by searching for this posting in the archive. To access the archive, click on Archive in the top bar of this blog.)

For people who are new to metal clay, the instructions on making your own extruder also provide a general background on how to use extruders, and especially on how to use them with tube adapters.

Here is an addition to the instructions:

I have all the discs that come with commercial extruders, but sometimes I need a different shape or size. Nothing is easier than making your own disc out of metal clay. When only silver clay was available, I wouldn’t even have considered it, due to the cost. But with base metal clay, making your own extruder discs is cheap and efficient.

It’s best to use low-shrinkage clay (Quick-Fire).

1. Roll a layer of clay 6 cards thick. Cut circles using a circle cutter that has the same diameter as the extruder.

2. Using a smaller cutter, cut any shape in the circles. After drying, you can change or refine the cutouts with a file.

Next I am going to try making my own tube adapter.

    Just amazing….and so great!…..not to mention generous.
    Thank you!

    Just making sure my computer color resolution is reading correctly and that I understand the diameter…your discs were done in bronze with the circles cut to match the OUTSIDE diameter of the extruder..to allow for shrinkage?

  • Hadar Jacobson Says:


    The shrinkage is not really n issue. Even if the discs shrink a bit, they will function just the same.

  • Cindy Pope Says:

    Yea Hadar!! Another great idea. I have been mixing my discs to get the shapes I want and then I can’t remember which ones I used to acheive the perfect ring band. Making my own is a fantastic idea.

    PS My first mixed metal piece turned out fantastic and I am thrilled with the quality of the detail I have been able to acheive with your bronze and copper clays.
