Lathe Turning

Precision Turning using a Template to create the Sugar Bowl with Lid and Creamer

Why you can do more with Template Turning


One of the better methods of creating accurate and precision-made models is the lathe method using a precision pre-cut template.

This method is particularly useful when clay shrinkage is involved. Normally, earthen ware clay loses 6.25% when fired; stoneware clays, 13%; and porcelain clays shrink 18% or even more.

Pencil draw the outline of the original item according to its real-time dimensions. Then enlarge this outline by what percentage of shrinkage using a photocopier. Transfer this enlarge drawing by tracing the outline onto a piece of metal, or, in his case, wood. Cut the metal or wood to form a precision template. Mount the template to the lathe. As the lathe begins to turn add wet plaster to the metal rod. Continue adding more plaster to the rod until the new model is completely formed by forming itself against the template.

MASTERLINE uses this method to create lamp bases, vases, pitchers, architectural moldings and so on.

Using the template method allows for the shrinkage of the fired clay body. As stated, most earthenware bodies shrink 6.25%. Stoneware and porcelain bodies will shrink even more. You can allow for these shrinkages by the increasing the size of the template by the appropriate percentages.

Over the years, MASTERLINE has created thousands of accurately design items using the template method -- long before CAD/CAM and CMC methods were developed.

Today, we offer custom-turned designs for many companies wishing to complete their projects in-house.
