ABSTRACT:
In the manufacture of a mould by the so-called lost wax method, the position and space occupied by a set of blank-carrying elongate members of fusible or calcinable material supported on an ogival head or cone are controlled by a gauge including a ring slidably mounted along a vertical rod. The gauge is then replaced by a cylinder forming a receptacle which receives a hardenable refractory material embedding said set. After hardening, the cone is removed and the fusible or calcinable material removed by heating to provide mould cavities.
