Shimming Video

Paul explains how to shim a clay figure as preparation for making a plaster mould. Firstly by cutting home made shims from soft drink cans. then carefully sliding the shims into place to enable a multi-piece mould to be made.

A plaster mould will next be made from the clay model. This mould needs to be in 2 sections and to achieve this, a barrier of metal "shims" is created through the middle of the model. I had to use cut up pieces of old beer cans. These need to fit very snugly together to prevent any plaster bleeding through the divide. An edge of clay is added to act as a clear marker once plaster is added.
