The head is lathed from aluminum. It fits on a potter's wheel (adjust the inside diameter to fit the shaft). The plaster mold drops into it this cuphead and stays in place by friction. The only point of contact between the mold and aluminum should be at the top inside corner of the cuphead.
Showing dimensions to fit a Shimpo RK2 wheel, its shaft is 0.983 in diameter. The molds fit down inside as shown, only contacting the cuphead at the shoulder. This is machined from aluminum. We do not sell this of course, but you could take this drawing to a machine shop and have them make you one (the numbers are readable when this is zoomed to full size).
Making a jigger mold for producing cereal bowls
A new way to 3D-print your way to making jigger molds and templates. The molds are encased in a 3D printed shell that makes them fit perfectly into the cuphead. And the template is precise and very effectivwe.
Project to Document a Shimpo Jiggering Attachment
Make your own jiggering attachment for your potter's wheel. Here are the plans and lots of help to get you going with molds and techniques.
Jiggering is a process of forming pottery that employs a spinning plaster mold and a tapered template to press soft clay or porcelain against it.
